Environment and Climate Change Canada (ECCC) is the federal department responsible for environmental protection, the national weather service, wildlife conservation, and climate change policy. ECCC develops and enforces environmental laws and regulations; delivers meteorological, hydrological, and air-quality services; protects species and habitats; advances climate science and adaptation; and represents Canada in many international environmental agreements.

Mandate and responsibilities

ECCC’s mandate is to protect the environment and conserve Canada’s natural heritage while supporting sustainable development and public safety. The department:

  • Develops regulations, standards, and compliance programs to prevent pollution and manage toxic substances.
  • Issues weather, marine, and severe-weather warnings, hydrological forecasts, and air-quality statements for public safety and economic sectors.
  • Conserves wildlife and habitats through the Canadian Wildlife Service (migratory birds, species at risk, protected areas).
  • Leads federal policies on climate change, including GHG reporting, carbon-pollution pricing framework (with provinces/territories), adaptation, and clean-technology programs.
  • Conducts and funds environmental science, monitoring, and research (atmosphere, climate, water, contaminants, ecosystems).

Meteorological Service of Canada (MSC)

The MSC is Canada’s national weather service. It operates weather radars, upper-air stations, surface networks, forecast centres, numerical weather prediction systems, and specialized programs (aviation, marine, Arctic, ice). It provides:

  • Public forecasts and alerts (watches, warnings, special weather statements) via weather.gc.ca, apps, and media partners.
  • Marine and ice information for oceans and Great Lakes; aviation weather for air navigation.
  • Air-quality services including the Air Quality Health Index (AQHI) and wildfire-smoke outlooks (FireWork model).
  • Open data (observations, radar, model fields) for researchers, media, and industry.

Environmental protection

Under the Canadian Environmental Protection Act (CEPA) and related laws, ECCC:

  • Assesses and manages risks from toxic substances; sets fuel and vehicle-emission standards; regulates industrial air and water emissions.
  • Oversees pollution prevention under the Fisheries Act (deleterious substances).
  • Monitors acid rain, ozone, POPs, and other transboundary issues; manages national pollutant inventories and reporting systems.
  • Operates an Enforcement Branch with designated officers who conduct inspections and investigations; prosecutions proceed through the courts with fines and court-ordered remedies.

Wildlife and protected areas

Through the Canadian Wildlife Service, ECCC:

  • Administers the Migratory Birds Convention Act and implements the Species at Risk Act (federal portion).
  • Establishes and manages National Wildlife Areas (NWAs) and Migratory Bird Sanctuaries (MBSs)—complementing Parks Canada’s terrestrial parks.
  • Works with provinces/territories, Indigenous governments, and partners on conservation planning (e.g., boreal caribou range plans, bird conservation regions), stewardship, and recovery actions.

Climate change, clean growth, and adaptation

ECCC coordinates federal climate policy, including:

  • National greenhouse-gas (GHG) inventories and reporting under the UNFCCC/Paris Agreement.
  • Carbon-pollution pricing framework (federal backstop where provincial systems do not meet benchmarks).
  • Regulations and programs to reduce emissions across sectors (transport, electricity, industry, oil & gas, buildings).
  • Adaptation initiatives: climate-data portals, risk assessments, and support for resilient infrastructure and communities.
  • International engagement: climate finance programming, negotiations, and multilateral environmental agreements.

Science, monitoring, and data

ECCC operates laboratories, observatories, and field stations across Canada. Core activities include:

  • Atmospheric and climate observations (greenhouse gases, aerosols, ozone/UV).
  • Water and ecosystem monitoring (rivers, lakes, contaminants, biodiversity indicators).
  • Numerical modelling (weather, climate projections, air quality, hydrology) and environmental prediction research.
  • Open science: publications, datasets, and geospatial services through Open Government portals.

Emergencies and public safety

ECCC supports public safety by:

  • Issuing timely weather alerts and providing data to the national Alert Ready system.
  • Delivering specialized impact-based briefings to emergency managers and critical sectors (transport, energy).
  • Producing spill trajectory and environmental advice during pollution incidents, and coordinating environmental aspects of federal emergency response with partners.

Programs, services, and engagement

  • Grants & contributions for community and Indigenous stewardship, climate and clean-tech projects, and habitat restoration.
  • Environmental assessments and expert advice to regulators under the Impact Assessment Act.
  • Public education resources on weather safety, climate, wildlife, and conservation.

History (brief)

  • 1871–1970s: Origins in the Meteorological Service; evolving federal conservation and pollution-control roles.
  • 1990s–2010s: Expanded environmental statutes; creation of the Canadian Wildlife Service within the department; modernization of weather radar and forecasting.
  • 2015–present: Renamed Environment and Climate Change Canada to reflect climate leadership; continued investments in observation networks, modelling, enforcement, and adaptation.
