Environment and Climate Change Canada (ECCC) is the federal department responsible for environmental protection, conservation, and climate change action. Key functions include weather forecasting through the Meteorological Service of Canada (issuing forecasts, warnings, and climate data), enforcing pollution prevention laws, protecting wildlife and managing protected areas, researching environmental conditions, and developing climate change policies. ECCC administers major legislation including the Canadian Environmental Protection Act and the Species at Risk Act. The department operates monitoring networks tracking air quality, water conditions, and wildlife populations across Canada. Municipalities interact with ECCC on environmental assessments for major projects, compliance with federal environmental regulations, wildlife management issues, and accessing climate data and adaptation resources. ECCC also leads Canada's participation in international environmental agreements.
