1. Introduction
Land degradation—defined as a persistent loss of ecosystem services and ecological integrity—is escalating globally. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) reported that degradation of the Earth’s lands and waters through human activities is negatively impacting the well-being of at least 3.2 billion people and costing more than 10% of the global annual gross domestic product (GDP) through loss of biodiversity and ecosystem services [1]. Ecosystem degradation is also a major contributor to climate change, with deforestation alone contributing about 10% of all human-induced greenhouse gas emissions [2].
Restoring degraded ecosystems has become an urgent policy priority. Avoiding and reducing ecosystem degradation is now inscribed on many global initiatives such as the UN-Reducing Emissions from Deforestation and Forest Degradation (REDD), the UN-Convention to Combat Desertification (UNCCD), the Convention on Biological Diversity (CBD), the United Nations’ Sustainable Development Goals (SDGs), and the Bonn Challenge—a global initiative to restore 350 Mha of deforested and degraded land by 2030. In 2021, the United Nations Decade on Ecosystem Restoration was launched with the objective to scale up and mainstream the various restoration programs and initiatives [3].
In recent years, the concept of ecological restoration has advanced significantly both as a scientific discipline and as a practical approach to support sustainable land use and adaptive land management [4,5]. An example of this evolution is the development of forest and landscape restoration (FLR) practices, which aim to provide principles for the management of multi-functional landscapes, where forestry, agriculture, and mining can be juxtaposed with other land uses such as recreation and conservation [6,7]. FLR exists as a type of restoration practice, but tends to offer more flexibility and multifunctionality than ecological restoration, as described by the Society for Ecological Restoration (SER) [8]. Considering its multiple benefits, FLR is described as a nature-based solution (NBS), which can help to address global societal crises such as biodiversity loss, climate change, natural disasters, and food and water security [9].
Canada was the first country in the world to develop a national policy framework for restoration of protected areas [10], forming the basis for the first global guidelines on restoration [11]. However, with the pace of cumulative effects accelerating, assessing the capacity of the regulation framework that governs restoration policies is paramount to safeguarding the natural capital of Canada. Examining the policy instruments that could support an FLR agenda in Canada is also crucial to establish goals and key measures required to meet international commitments toward restoration, climate change, protected areas, and biodiversity [12].
Accounting for up to 40% of 979 Mha total land, Canadian forest landscapes are a global natural capital legacy. Canada contains 30% of the world’s boreal forest, 9% of the world’s overall forest area, and 20% of the world’s freshwater resources, including peatlands acting as some of the largest carbon pools in the world [13]. Canada’s economic wealth is strongly rooted in the extraction and export of its natural resources and represents, therefore, an opportunity to assess the importance of environmental policies supporting FLR activities. As one of the largest natural resources sectors in the world [14], the forestry, mining and energy sectors are major industries operating on forested landscapes, together contributing over 10% of Canada’s GDP [15]. Management of natural resources is the responsibility of Canada’s provinces and territories (P&Ts), and implementation of strong environmental policies is key to ensuring healthy and resilient ecosystems as well as a competitive natural resources sector.
Increasing global demand for natural resource commodities has also brought increased attention to Canada’s environmental policies on the international scene, including protection of species at risk, environmental performance of the energy sector, efforts to achieve international sustainability targets, and building relationships with Indigenous Peoples [16,17,18]. Despite the declining trend in deforestation in Canada (Appendix A: Figure A1), the cumulative effects of anthropogenic and natural disturbances in space and time can impede the sustainable management of natural resources and the ability to maintain biodiversity, environmental, social, and cultural values of the landscapes [19,20]. Furthermore, forest regions across Canada are already experiencing the impacts of climate change, resulting in altered vegetation, ecosystem services, biodiversity, carbon cycles, and natural disturbance regimes (e.g., fire and pests) [21,22]. In addition, Indigenous populations are increasingly impacted by climatic change given their close relationship with the environment and their reliance on the land for their well-being and health [23]. Therefore, natural and anthropogenic disturbances in Canada are intermingling in the landscape and there is a broad agreement that mitigation and reversing measures are essential to prevent further damage to the health of ecosystems and peoples [24,25,26,27].
This paper reviews and examines current legislations and policies supporting FLR at the P&Ts and federal levels to assess Canada’s capacity to accelerate restoration planning and efforts. First, a literature review was completed to assess the policy dimension of FLR found in scientific publications and compare trends at the global and national levels. Then, a Canada-wide legislation and policy scan was conducted using national and governmental databases.
2. Terminology and Methodology
Ecological restoration is a relatively young discipline and in constant evolution, hence the evolving terminology [28]. The Society for Ecological Restoration, the leading global network of professionals in this field today, defines ecological restoration as “the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed” [8]. We adopt a broad view of restoration as encompassing to greater and lesser extents a wide variety of environmental practices that also vary from region to region. Therefore, various terms were used in the publication search in order to capture this variability. For example, the search for restoration-related policies included keywords such as (1) mitigation, restoration, recovery, reclamation, remedy, and rehabilitation in the context of environmental assessment and mining; (2) protection and conservation in terms of wildlife habitat and protected areas; and (3) renewal, reforestation, and afforestation as part of sustainable management of forests. Because we were interested in FLR in the context of sustainable land use management, the research was focused on terrestrial forested ecosystems as opposed to marine and coastal ecosystems.
First, a broad quantitative literature review was performed to assess the extent of the policy representation in ecological restoration scientific publications at the national and global levels. The number of scientific papers published was assessed in the Web of Science Core Collection General from 1990 to 2021 with search terms used including the following: (1) (restoration OR restored OR reclamation OR reclaim) AND (ecosystem * OR ecol *); (2) (restoration OR restored OR reclamation OR reclaim) AND (ecosystem * OR ecol *) AND (forest * OR woodland OR terrestrial); (3) (policy OR legislat * OR law) AND (forest * OR land *) AND (restored OR restoration OR reclamation OR reclaim); (4) (“forest governance” OR “land * governance”); and (5) (“forest landscape restoration”) in title, abstract, and keyword fields. In a literature database search, a search term ending with an asterisk (*) returns results with topics including the search term before the asterisk and the possible extension of the term. For example, “ecol *” used in this paper returned publications containing keywords like ecology and ecological. In addition, search terms in quotation marks return results that contain the entire query in the quotation marks. To extract publications in the context of Canada from the search results, an extra search term, AND (Canada *), was added to each combination of search terms.
Secondly, a Canada-wide scan was conducted using a variety of sources including Canadian Legal Information Institute, Canada’s Justice Laws website, and other relevant federal and provincial/territorial government websites. The Canadian Legal Information Institute is the primary source of Canadian law, both legislative and judicial, from federal to provincial/territorial jurisdictions, offering free public access to more than 2.4 million documents across more than 300 databases. For the purpose of our study, public policy was interpreted as “a set of decisions by governments and other political actors to influence, change, or frame a problem or issue that has been recognized as in the political realm by policy makers and/or the wider public” [29]. Multiple levels of public policy and legislation were thus assessed in this paper and their definitions are as follows: Act, also called a statute, is a law passed by the provincial or federal legislature. Regulation, also called delegated legislation, is a law made by the government, not the legislature, to provide details to give effect to the policy. Additionally, guidelines, standards, frameworks, and best practices pertaining to FLR were explored and evaluated. Guidelines, standards, or frameworks, while there is no force of law, are documents that interpret legislation and/or regulation and provide technical specifications and requirements to advise how to comply with them. Although fundamentally different in their objectives and application, legislations and policies have been addressed together in this study because legal obligations for restoration are just as important as practical guidelines to ensure that restoration activities are implemented and monitored using the best available science [30]. It is important to emphasize that this study does not pretend to be exhaustive and to examine each policy in detail, but rather to provide an overview of the policy dimension of FLR in Canada and, above all, to identify the most important gaps and pathways to implement effective restoration actions.
3. Results
3.1. Publication Trends in Ecological Restoration
Globally, published research on ecological restoration has increased exponentially over time since the restoration movement was initiated in the early 1990s, right after the formation of the SER in 1989. This trend has been even more pronounced since 2000 as the number of publications increased more than 17-fold from 250 papers in 2000 to 4279 in 2021 (Figure 1a). Ecological restoration studies specific to forest, woodland, or terrestrial ecosystems showed a steady increase around the globe. On the other hand, restoration-policy-related research remained largely under-documented, as the number of publications on this topic was about 11% of the annual publications on ecological restoration during the search period (1990 to 2021). The number of publications on forest governance research was at around 4% of the annual number of ecological restoration literature; however, there was a notable increase over the last decade from an average of 13 publications over a 10-year period between 2002 and 2011 to 102.8 publications between 2012 and 2021. The term “FLR” started to be mentioned in scientific publications around 2007 and has gained more interest during the last decade, yet the number of publications is very low.
In Canada, similar publication trends were observed at a relatively lower volume than global trends with a major increase in publications pertaining to ecological restoration and terrestrial ecosystem restoration after 2014 (Figure 1b). Policy research related to FLR was still in its infancy in Canada during the 1990s and 2000s as the average number of publications was 1 and 2.2, respectively, during those periods. This research topic gained more attention over the last decade with an average of 4.2 papers published between 2010 and 2021, which was about 10% of the ecological restoration literature in Canada. The term “governance” in the context of forest and landscape only started to emerge in the literature since 2010 in Canada and the governance-related publications between 2010 and 2021 were about 5% of the number of publications on ecological restoration.
3.2. Forest Landscape Restoration Related Policies at the Federal, Provincial, and Territorial Levels
We identified almost 200 policy instruments supporting FLR directly and/or indirectly at the federal and P&T levels in the form of Acts (Table 1, Appendix B) as well as in the form of guidelines, standards, frameworks, and best management practices (Table 2, Appendix C). Specifically, our results show that FLR is mandated and supported under five types of land use and resource extraction activities: (1) mining and oil and gas activities; (2) sustainable forest management; (3) environmental impact assessment; (4) conservation and restoration of ecosystem integrity in protected areas and parks; and (5) protection and conservation of species at risk and their habitats. In addition, FLR policies were recently added to the national climate change mitigation agenda as part of the nature-based solutions program and the net-zero emission strategy [31,32]. We have also noted that these technical documents are often developed in collaboration with multi-jurisdictional working groups (government, academia, NGOs, industries) and hands-on restoration practitioners. The policy instruments are listed in Table 1 and Table 2 and in Table A1 and Table A2 in the appendix by purpose and by jurisdiction. The context of their application is described as follows.
3.2.1. Mining, Oil, and Gas Activities
Mitigation of disturbed landscapes following oil, gas, and mining activities is a major driver of restoration and reclamation policies across Canada, especially in the provinces of Alberta, British Columbia, and Saskatchewan (Table 1 and Table 2). In the context of mining, oil, and gas activities, restoration and reclamation are used interchangeably to describe the activities related to the removal and decontamination of materials, decommission of structures, and reconstruction of the disturbed land through revegetation. We have identified multiple policies mandating restoration and reclamation following mining, oil, and gas activities in every province and territory except Nunavut (Table 1). Most of these policies, such as the Mineral Act, Mining Act, and Oil and Gas Act, have an environmental section to ensure that rehabilitation and restoration plans are integrated into the development of the project. As an example, the Mining Act (Section 232.3) of Quebec states “rehabilitation and restoration plans shall contain, in particular, the description of the rehabilitation and restoration work relating to the mining activities carried on by the person submitting the plan and intended to restore the affected land to a satisfactory condition” Further, technical specifications for meeting restoration criteria are instructed in guidelines and/or manuals in each province and territory (Table 2).
Given its long-standing position as one of the top oil and gas producers in the world, the province of Alberta has more than 50 years of experience with environmental policies containing specific regulations and guidelines for reclamation of disturbed landscapes (Table 3). As a key driver of restoration and reclamation activities, Alberta became the first province in Canada to enact legislation on land reclaimed in 1963 (Table 3). Since 1993, the Environmental Protection and Enhancement Act mandates restoration and land reclamation of sites to its “equivalent land capability”, which is defined as the ability of the land to support various post-disturbance land uses that are similar to pre-disturbance conditions, but not necessarily identical to them, based on topography, drainage, hydrology, soils, and vegetation (Section 1(e) and 1(k) of Conservation and Reclamation Regulation).
In addition to legislation to assist mining and oil and gas site closure, we found that multiple restoration and reclamation guidelines have been developed by practitioners in every P&T (except Prince Edward Island) to focus on particular features of the landscape such as coal mines, orphaned well, tailings ponds, seismic lines, or wetland (Table 3). Reclamation activities are also supported by practitioners and associations such as the Canadian Land Reclamation Association, formed in 1975, who provide technical support and networking to implement restoration and reclamation on the ground [33].
3.2.2. Sustainable Forest Management
Federal and P&T’s sustainable forest management legislations and policies support restoration in various ways (Table 1 and Table 2). Sustainable forest management (SFM) and forest stewardship in Canada are directed by the Canadian Council of Forest Ministers which was established in 1985 by the federal, provincial, and territorial ministers responsible for forests to set the overall direction for SFM at the national level. Since then, SFM in Canada uses criteria and indicators based on the internationally recognized Montreal Process [35]. The framework consists of 6 criteria and 46 indicators, with the 6 criteria being (1) biological diversity; (2) ecosystem condition and productivity; (3) soil and water; (4) ecological cycles; (5) economic benefits; and (6) society’s responsibility. Restoration and reforestation efforts are mentioned in criteria 1 and 2 to improve the genetic diversity and improve vulnerable, threatened, and endangered species, respectively. Afforestation is also mentioned in criteria 2 in order to accelerate carbon sequestration. In addition, Canada reports on its progress on forest sustainability in its annual State of Canada’s Forest report, which presents current information on trends and statistics related to sustainable forest management in Canada and provides comprehensive data sources and information [36]. It tracks various indicators pertaining to sustainability including forest area, deforestation and afforestation, and forest regeneration, among other forest-sustainability-related indicators (Appendix A, Figure A1).
Ninety-three percent of Canada’s forest land is publicly owned (defined as Crown lands) and managed under P&T legislation. While less than 800,000 ha are harvested every year, forest loss caused by forestry activities remains significantly low at 0.014% of Canada’s forest per year between 2005 and 2010 (Appendix A, Figure A1). Successful regeneration is required following forest harvesting on public lands. In 2018, at least 427 million seedlings were planted on 350,000 ha of provincial forest lands in Canada. An additional 6000 ha of forest were established by seeding (Appendix A, Figure A1).
In some P&Ts, including Alberta, Saskatchewan, Ontario, Québec, and Prince Edward Island, forest policies are written in a way that reflects the principles of ecological restoration, such as the conservation and protection of ecologically critical areas and maintenance of healthy ecosystems and ecological processes by mimicking natural disturbances regimes such as wildfire. In addition to the commercial value of the forest, forest management plans are required by P&T laws to ensure that forest industries integrate other ecosystem values and services (e.g., soil, water, wildlife, and biodiversity) into their agreement or licence application.
3.2.3. Environmental Impact Assessment
Starting in 1992, resource development projects occurring in areas under federal jurisdiction were required to conduct assessments under the Canadian Environmental Assessment Act (CEAA). The CEAA and its regulations established the legislative basis for the federal government to “identify potential adverse environmental effects; propose measures to mitigate adverse environmental effects; predict whether there will be significant adverse environmental effects, after mitigation measures are implemented; and includes a follow-up program to verify the accuracy of the environmental assessment and the effectiveness of the mitigation measures” [37]. The CEAA was replaced by the Impact Assessment Act (IAA) in 2019; the new Act lays greater emphasis on meaningful consultation and engagement with Indigenous Peoples and local communities and the integration of traditional knowledge and the rights of Indigenous Peoples into the environmental assessment process. Moreover, the IAA expands on the meaning of “adverse effects” from significant adverse environmental effects under CEAA to all effects (both positive and adverse) and requires mitigation measures to eliminate, reduce, control, or offset the adverse effects and to pay for any damage through restoration or any other means (IAA, Section 22.1).
All P&Ts have environmental assessment and protection policies in place to require the identification of environmental impacts and mitigation measures during the various phases of project development (Table 1 and Table 2). With varied terms and definitions, mitigation measures in general indicate actions to recover an ecosystem to a former condition, to a beneficial use, or to a condition satisfactory to the government and are required in an application for project development.
3.2.4. National Parks and Protected Areas
Parks Canada developed the first national principles and guidelines for ecological restoration in the world [10]. These guidelines formed the basis for the first global advice on restoration [11]. Developed in collaboration with the SER and the Indigenous Peoples’ Restoration Network, these principles describe an approach to ecological restoration that will ensure that parks and protected areas continue to safeguard ecological integrity while providing opportunities for meaningful engagement with multiple stakeholders and rights-holders (e.g., Indigenous Peoples, NGOs, communities, and visitors) within the network of Canada’s protected areas. The Canada National Parks Act (Section 8.2) also provides a legal basis for maintenance and restoration of ecosystem integrity through preserving ecologically critical areas at a landscape scale on federal lands This Act defines that a national park should conserve and restore regional characteristics such as abiotic components and biodiversity to support ecological processes (e.g., natural disturbances and prey–predator dynamics) and ecosystem integrity in a broader sense [10].
Every province and territory has enacted at least one policy to support the designation and management of protected areas and parks for ecological purposes on public lands (Table 1). The designation of protected areas and parks at provincial and territorial levels is more complete than at the federal level in that they include wilderness areas, ecological reserves, conservancies, areas for tourism, natural areas, and heritage rangelands (i.e., a mix of strict protection, research, or human use).
In addition to the policies that regulate and promote FLR within protected areas, we found the emergence of policies supporting Indigenous-led conservation initiatives such as Indigenous Protected and Conserved Areas (IPCAs), for which restoration of degraded landscapes is central to regaining ecological integrity (Table 2). These policies are often guided by multiples goals, including developing Indigenous leadership and stewardship to conserve, restore, and manage the land, but foremost rebuilding relationships between the federal and Indigenous governments in the spirit of reconciliation. As an example, the Indigenous Guardians Program, led by Environment and Climate Change Canada (ECCC), aims to recognize Indigenous rights and reconciliation in protecting and conserving ecosystems, as well as developing and maintaining sustainable economies in healthy ecosystems [38]. This program is also accompanied by a Nature-Smart Climate Solutions Fund to support Indigenous-led projects that restore and enhance wetlands and grasslands to mitigate climate change.
3.2.5. Species at Risk and Their Habitats
Recovery and habitat management for species at risk is also an important driver of restoration activities on forested land. The federal Species at Risk Act (SARA) is a result of the implementation of the Canadian Biodiversity Strategy in response to the United Nations Convention on Biological Diversity [39]. The purposes of the Act are “to prevent wildlife species from being extirpated or becoming extinct, to provide for the recovery of wildlife species that are extirpated, endangered or threatened as a result of human activity and to manage species of special concern to prevent them from becoming endangered or threatened” (SARA, Section 6). An independent body of experts, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), exists to provide scientifically sound assessments to identify and classify species at risk. SARA applies to species found on lands administered by a federal government (e.g., national parks) and species falling under federal legislative powers (e.g., aquatic species and migratory birds under the Migratory Birds Convention Act (1994)) [40,41]. However, the Canadian federal government can issue emergency orders under SARA (SARA, Section 80) for species of concern that are found outside of its jurisdiction and “face imminent threats to its survival or recovery” (SARA, Section 80.2) when provincial or territorial governments fall short of taking acceptable action to protect the species.
One of the well-documented examples of SARA implementation on non-federal lands is the federal recovery strategy of the woodland caribou (Rangifer tarandus caribou), which has been listed as threatened since 2002 [42]. Under SARA, the federal recovery strategy was developed in collaboration with various organizations, including P&Ts, to establish range plans that ensure at least 65% of the caribou range is undisturbed [43]. One of the three pillars of the recovery strategy recommends to “conduct research to optimize habitat recovery through forest landscape restoration approaches and the development of tools and practices to support restoration success at the site level“ [44]. In addition to SARA, the Canada Wildlife Act designates wildlife areas for research and/or critical habitat protection purposes (e.g., migratory birds and at-risk species), although the intent of the Act is to mainly regulate hunting activities.
Similar to the federal level, wildlife policies in P&Ts were originally developed to regulate hunting activities, but have since shifted their focus to also include legal requirements concerning conservation and protection of endangered species and their habitats (Table 2).
3.2.6. Climate Change
Recently, the Canadian Climate Change Adaptation and Actions Plan has added significant emphasis on FLR, where “protecting and restoring nature are important parts of Canada’s efforts to mitigate and adapt to climate change” is transversal to multiple land uses [45]. Nature-based solutions are central in this strategy to protect 25% of Canada’s land by 2025 and reach net-zero greenhouse gas (GHG) emissions by 2050 to fight climate change. For example, the 2 Billion Trees program led by Natural Resources Canada (NRCan) and the Nature-Smart Climate Solutions program led by ECCC are the two main federal programs where restoration of forested landscapes (including urban forests) is key to meeting climate targets and other SDGs (Table 2). Both programs aim to achieve multiple objectives towards enhanced ecosystem management and reduced GHG emissions by supporting tree planting to increase carbon sequestration and forest resilience to climate change, while promoting landscape restoration for biodiversity. The programs also have a socio-economic dimension to support human well-being, especially in Indigenous communities, by creating green jobs and reducing community risks to natural disasters like wildland fires and floods [45].
4. Discussion
4.1. Closing the Gaps in Restoration Science, Policy, and Practice
The observed increase over time in the number of restoration-related publications in our literature review confirmed that halting and reversing current trends of degradation by scaling up restoration efforts is gaining importance in Canada and globally. The results also showed that the policy dimensions of restoration remain largely under-documented in the scientific literature despite their key role in implementing effective restoration measures on the ground [46,47,48,49]. This trend confirms the complexity of integrating restoration policies more broadly into environmental law [50,51]. Too often, restoration legislation faces challenges at the implementation stage and fails to mitigate the impacts of rapid global changes at the local and regional scales [52]. Despite the political momentum at the international level, the implementation of effective restoration project on the ground can be difficult, as public-facing commitments do not necessarily reflect actual policy and practices [53]. Recent research suggests that restoration implementation is constrained at the national level for reasons that include financial capacities, access to data, lack of monitoring, inadequate policy and governance, community opposition, existing land-use entitlements, and the lack of meaningful legal accountability for compliance [30,54]. Moreover, given the cumulative effects of environmental and anthropogenic stressors, complex and synergistic impacts operating over a large range of spatiotemporal scales can challenge the effectiveness of individual restoration projects [55]. Indeed, while millions of hectares of land worldwide have been committed to restoration, many landscape and ecosystem restoration initiatives are unlikely to be effective given incomplete or inadequate policy, including poor monitoring practices and the lack of long-term and adaptative management plans [56].
Therefore, a policy scan such as this study represents a practical tool for learning lessons and identifying gaps in future policy development and research. However, such studies remain rare in the literature. Without conducting an extensive search, we identified only two studies similar to ours, one from Australia [57] and one from the United States [58], both of which examined decades of existing restoration programs or policies. Both concluded that, despite science-based policies and best practices, implementation remains too fragmented, often confined to a particular ecosystem or land type, and difficult to scale up without massive investment and effective collaboration with multiple stakeholders.
Considering the changing paradigm towards the multifunctional values of the landscape as well as the need for integrating climate change mitigation into land-use management, it is essential to realign restoration policy and restoration science to accelerate the recovery of degraded landscapes in the current context [12,47,59]. In a rapidly changing world, where historical ecosystem conditions are altered by multiple land uses and environmental stressors, the concept of novel ecosystems is an example of pragmatic and flexible approaches to help achieve restoration goals [60,61,62]. A novel ecosystem is defined as “a system of abiotic, biotic, and social components (and their interactions) that, by virtue of human influence, differs from those that prevailed historically, having a tendency to self-organize and manifest novel qualities without intensive human management” [60]. While the novel ecosystem concept has become popular over the last decade, it has also raised debates in the restoration community [63,64]. Interestingly, while there is mounting evidence that the fundamental environmental drivers of ecosystems are undergoing unprecedented change, policies are still limited to conventional approaches for restoring lost ecological processes and enhancing ecosystem services in transformed landscapes where such a return is deemed infeasible.
With the need to build more capacity across restoration practitioners and organisations, the United Nations Decade on Ecosystem Restoration, launched in collaboration with the FAO, represents a unique opportunity to bring together and bring into the mainstream the various restoration pathways and objectives in a coordinated manner, as well as to massively scale up restoration projects across the globe [65]. With restoration principles and guidelines becoming more available and applied [8,66,67,68], there is an opportunity to bridge the gaps between restoration science and the policy agenda and develop a shared vision of ecosystem restoration. As the discipline of restoration is evolving rapidly, policymakers, in Canada or elsewhere, are in a unique position to develop science-based and flexible policies that account for the full set of ecosystem restoration objectives and values and that strengthen the capacity for practitioners and scientists to respond to ongoing and future changes [59,62].
4.2. Reviving Canadian Leadership in Restoration
Although our study is not exhaustive and shows only a 360-degree view of the FLR policy dimension, our results highlight that Canada is well equipped in terms of FLR legislations and policies. Indeed, driven by one of the largest natural resources sectors in the world, Canada plays an outsized role in leading and developing the field of ecological restoration, as represented by the Canadian membership (14%) of the SER (the highest per capita in the world). Since 1989, three of eleven chairs of the SER have been Canadian. Canadian universities such as the University of Alberta and the University of Victoria have been pioneers in developing world-class restoration programs and certificates [69]. The numerous policy instruments listed in this study reflect the need to ensure profitable, but sustainable access to those natural resources for the benefit of Canadians, as well as to maintain competitiveness in the international market. Canada was the first industrialized country to sign and ratify the CBD in 1992 and is recognized as a global leader in sustainable forest management. In addition to leading the world in forest certification (as of 2018, Canada had 164 Mha of independently certified forest land, representing more than 48% of the country’s forests and 37% of all certified forests worldwide; [70]), Canada is among the few countries to have implemented science-based criteria and indicators to monitor deforestation [71].
Despite the numerous policy instruments available, the execution of environmental legislation in Canada has been challenged lately [16,72]. Indeed, reclamation activities in the oil patch in Alberta have epitomized the complexity of implementing effective restoration, despite the 50 years of active legislation [37,73]. The same is true for the implementation of SARA in the context of the woodland caribou recovery strategy [44,74,75]. Therefore, a fundamental challenge for the Canadian land sector will be to convert policy aspirations into realisable and quantifiable targets in conjunction with other land-use objectives and values. Given the rapid changes in structure, function, and human dimension in Canadian forests, there is an opportunity to develop a more adaptive and inclusive restoration agenda [60,76,77]. For example, given the mounting recognition of the significant role that Indigenous Peoples play in biodiversity conservation and the protection of cultural heritage [78], Canada could lead the way in supporting Indigenous-led conservation and restoration initiatives like IPCAs. Supporting Indigenous leadership and integrating Indigenous knowledge can help to transform the policy, governance, and management of conservation actions and honor the Indigenous relationships with the land and the nation-to-nation reconciliation [79]. Capacity building and collaboration with Indigenous Peoples is thus essential to develop more holistic practices in order to achieve the multiple goals of restoration.
Moreover, with the valuation of natural capital and NBS becoming more tangible as part of solutions to mitigate climate change [80,81,82], Canada is well positioned to invest in its natural capital to limit the negative impacts of climate change and contribute to the Paris Agreement. In the case of highly altered landscapes, where historical conditions have been lost beyond which the practical efforts of traditional restoration are feasible, combining flexible approaches with NBS to design future ecosystems and green infrastructure should be investigated further [83,84]. Finally, another pathway to galvanise restoration activities through policy-making is to recognise and invest in the restoration economy [69]. Supporting already more than 400,000 employees through activities related to site assessment and reclamation in Canada, the restoration economy is a promising sector to simultaneously ease pressure on the environment and create jobs and revenues [85,86,87]. With a more inclusive and adaptive restoration agenda developed to respond to ongoing and future changes, Canada can forge new pathways to establish goals and identify key measures to meet its international commitments to restoration, climate change, and biodiversity conservation.
5. Conclusions
Considering the imperative to mitigate and lower the pace of environmental degradation, this study provides the first national restoration policy scan in Canada focusing on forests. Our review highlights that restoration is gaining significance as a research topic globally and in Canada, while the policy dimension of restoration remains under-documented, as observed worldwide. Although not exhaustive, our study also highlights that, given its large natural resources sector and SFM practices, Canada has established itself as a pioneer in restoration supported by science-based policies and long-term collaboration between the industrial forestry sector, the different levels of government, and academia. However, as the uses and values of forested landscapes are changing rapidly, the main challenge will be to develop multi-stakeholder approaches including Indigenous Peoples to implement policy aspirations into realizable and quantifiable targets in conjunction with other land-use objectives and values. In the face of increasing pressures on the landscapes, a changing climate, and increased societal demands for ecosystem services, the research–policy interface is needed more than ever not only to respond to ongoing and future changes, but also to generate applied knowledge transferable into the land-use and restoration agenda.

Appendix A
Figure A1. (a) Estimated areas of annual deforestation and (b) causes of deforestation in Canada as of 2017 by industrial sector. Canada has 347 Mha of forest area (2017). Canada’s low annual deforestation rate has declined over the last 27 years, dropping from 64,000 ha per year (ha/yr) in 1990 to about 35,000 ha/yr in 2017. Between 1990 and 2017, less than half of 1% of Canada’s total forest area was converted to other land uses. Deforestation is defined as the permanent clearing of forests to non-forest land uses [36].

Abstract
Restoring degraded ecosystems is an urgent policy priority to regain ecological integrity, advance sustainable land use management, and mitigate climate change. This study examined current legislation and policies supporting forest landscape restoration (FLR) in Canada to assess its capacity to advance restoration planning and efforts. First, a literature review was performed to assess the policy dimension of FLR globally and across Canada. Then, a Canada-wide policy scan using national databases was conducted. While published research on ecological restoration has increased exponentially in Canada and globally since the early 1990s, our results showed that the policy dimensions of FLR remain largely under documented in the scientific literature, despite their key role in implementing effective restoration measures on the ground. Our analyses have identified over 200 policy instruments and show that Canada has developed science-based FLR policies and best practices driven by five main types of land use and extraction activities: (1) mining and oil and gas activities; (2) sustainable forest management; (3) environmental impact assessment; (4) protected areas and parks; and (5) protection and conservation of species at risk. Moreover, FLR policies have been recently added to the national climate change mitigation agenda as part of the nature-based solutions and the net-zero emission strategy. Although a pioneer in restoration, we argue that Canada can take a more targeted and proactive approach in advancing its restoration agenda in order to cope with a changing climate and increased societal demands for ecosystem services and Indigenous rights. Considering the multifunctional values of the landscape, the science–policy interface is critical to transform policy aspirations into realizable and quantifiable targets in conjunction with other land-use objectives and values.
