Environmental impact study, natural heritage screening, species at risk assessment, and Class EA process: supporting permits for solar farms, substations, transmission lines, and infrastructure projects.

Do solar farms require an Environmental Impact Assessment?

Large solar farms on greenfield land typically require a Natural Heritage Assessment, species at risk screening, and sometimes a full Environmental Impact Study depending on municipal and Conservation Authority requirements. Projects near wetlands, woodlands, or watercourses have additional triggers.

Key Deliverables

• Environmental Impact Study (EIS) report
• Natural heritage screening and assessment
• Species at risk habitat assessment
• Wetland boundary delineation
• Tree inventory and preservation plan

What is the Ontario Class EA process?

Ontario's Environmental Assessment Act requires Class EAs for routine infrastructure projects. Schedule A is pre-approved (minor). Schedule B requires screening and public notice. Schedule C requires the full Class EA process with alternatives analysis and public consultation. Timeline ranges from weeks (Schedule A) to 1–2 years (Schedule C).
