Strategic environmental assessments
Parks Canada uses two layers of impact assessment. Project-level assessments are one layer. The other layer is strategic environmental assessment (SEA). This layered system is part of a robust framework to assess the impact of project proposals on national parks, marine conservation areas and historic sites. The framework ensures that ecological integrity, ecological sustainability and commemorative integrity are protected. Protection of heritage areas is what enables Parks Canada to provide meaningful services and experiences to visitors.
Understanding cumulative effects
Project-level impact assessments are necessary. But they are not always the right tool to identify broader cumulative effects. A cumulative effect occurs when multiple human actions combine to have a negative impact on the environment. Other external factors like climate change may also contribute to the effect. To understand cumulative effects, we need to view the environment through a wider lens than a project-level assessment.
For example, turtles can be impacted by multiple human actions within one park. Turtles can be hit and killed by vehicles on the road. Some might be taken illegally for the pet trade. A shoreline project could interrupt turtles’ access to their nesting habitat. Meanwhile, a warmer climate may reduce the extent of wetland habitat available to turtles. The combined impact of all these concurrent stressors is a cumulative effect on turtles.
Strategic environmental assessment enables Parks Canada to consider this big-picture view. It is applied to policies, plans and programs. For example, we do strategic environmental assessment on 10-year park management plans. This allows us to evaluate cumulative effects over a region. We identify the gaps in our knowledge, and the methods and tools needed to manage cumulative effects. The process can also uncover opportunities to boost positive effects. The findings of strategic environmental assessment are used to ensure that project-level assessment is effective.
Federal requirements for strategic environmental assessment
The Cabinet Directive on the Environmental Assessment of Policy, Plan and Program Proposals (2010) requires federal agencies to conduct strategic environmental assessments on proposed policies, plans and programs when:
- The proposal is submitted to an individual minister or Cabinet for approval.
- Implementation of the proposal may result in important environmental effects, either positive or negative.
Even when the above conditions are not met, Parks Canada may elect to undertake one if it would be beneficial. Specifically, Parks Canada may elect to undertake a strategic environmental assessment on any policy, plan or program proposal that:
- could result in adverse effects to the Parks Canada mandate
- could result in significant interest from Indigenous groups, members of the public, or stakeholders about important negative effects on the environment or about the Parks Canada mandate
- involves multiple project-level assessments that would benefit from a strategic review
Parks Canada may require strategic environmental assessment of:
- Memoranda to Cabinet
- Treasury Board submissions
- new or amended legislation or regulations
- Protected area establishment
- Protected area management plans
- Species at risk recovery strategies and action plans
- ski area planning
- national policies and plans
- community plans
- other proposals for specific national parks, national historic sites, and national marine conservation areas
Statements on strategic environmental assessment
Parks Canada is required to provide a public statement that summarizes the strategic environmental assessment when a proposal is approved. The assessment itself may be documented in a stand-alone report, or it may be incorporated into the assessed policy, plan or program.
