National marine conservation areas of Canada (NMCAs) protect representative examples of Canada’s marine heritage—Great Lakes and ocean waters, the water column, lake/sea floor, and associated ecosystems—while allowing ecologically sustainable use. NMCAs are administered by Parks Canada in collaboration with Indigenous governments and coastal communities.

Overview

Unlike national parks (which emphasize ecological integrity on land), NMCAs are large, living seascapes. They protect biodiversity, cultural sites, and representative marine regions while accommodating human uses that are compatible with long-term conservation—commercial and recreational activities are managed through zoning, permits, and monitoring.

How NMCAs work

  • Zoning: Core conservation zones protect sensitive habitats (reefs, seabird colonies, ice edges); multiple-use zones allow activities that meet ecological standards.
  • Co-management: Indigenous rights and knowledge are central. Many NMCAs are developed and managed with Indigenous partners through agreements and advisory bodies.
  • What’s allowed: Boating, paddling, wildlife viewing, research, commercial shipping and fishing (where consistent with conservation objectives). Seabed mining and oil & gas are generally excluded.
  • Monitoring & stewardship: Science and Indigenous knowledge guide adaptive management; education programs promote safe, low-impact access.

Current sites

Site Province/territory Year (status) Approx. area Highlights
Lake Superior National Marine Conservation Area Ontario 2015 ≈ 10,000 km² Granite islands, lighthouses, cold-clear freshwater, fish habitat, shipwrecks

Planning & future candidates

Parks Canada continues to evaluate additional marine regions with Indigenous governments and provinces/territories. Candidate areas move through feasibility studies, impact/benefit agreements, and zoning plans before formal designation. *(Examples often discussed include additional Pacific, Atlantic, Arctic, and Great Lakes sites; statuses evolve.)*
