How oceans benefit Canadians
Description: How oceans benefit Canadians
The Census of Environment organizes data on ecosystems, like those found in oceans, through natural capital accounts. This helps us to understand how nature, society and the economy are interconnected and to examine the costs and benefits of conservation, development and use of resources.
Natural capital accounts provide information on the extent and condition of ecosystems, the services they provide and their value.Note 1
- Extent: Canada has 5.8 million km2 of ocean area.
- Condition: Canada’s oceans have warmed since 1982.
- Ecosystem services: In 2023, 638 kilotonnes of wild fish and seafood were harvested commercially from Canada’s oceans.
- Estimated value: Commercial fishing, carbon sequestration and nature-based tourism—three ecosystem services provided by oceans—were valued at $7.1 billion in 2023. Commercial fishing represented $1.2 billion of this amount.
Changes in the extent and condition of ocean ecosystems can impact the services they provide to humans.
Ecosystems like seagrass meadows provide shelter and nursery habitats for marine wildlife such as fish, crustaceans and mollusks. They also sequester carbon in coastal sediment.

Warming oceans can affect fish and seafood directly (e.g., decreased reproduction) and indirectly (e.g., changes to their habitat). This could impact their future contribution to the economy and food supply.
