Terrestrial ecoregions of Canada
Imagine Canada as a giant puzzle! This article lists the different "puzzle pieces" called ecoregions in Canada. An ecoregion is a large area of land or water. It has its own special mix of plants, animals, and ecosystems. These areas are identified by the World Wide Fund for Nature (WWF). They help us understand and protect nature.
Land Ecoregions: Canada's Natural Zones
Canada has many different land ecoregions. They are all part of a bigger area called the Nearctic realm. This realm covers most of North America. The Nearctic realm, along with the Palearctic realm in Europe and Asia, forms the Holarctic realm. This huge area covers the northern half of the world.
British Columbia is Canada's most diverse province. It has 18 different ecoregions! These regions spread across four main types of natural areas, called biomes. On the other hand, Prince Edward Island is much smaller. It has only one ecoregion. This single ecoregion, called the Gulf of St. Lawrence lowland forests, covers the whole island.
What are Biomes?
A biome is a very large natural area. It has a specific climate, plants, and animals. Think of it as a major type of habitat. Canada has several biomes, from cold tundras to vast forests.

Marine Ecoregions: Canada's Ocean Zones
Canada is special because it touches three huge ocean areas. These are called marine realms. They include the Arctic Ocean, the Temperate Northern Atlantic, and the Temperate Northern Pacific.
These large ocean realms are divided even further. They contain three main types of marine biomes. Within these biomes, there are fifteen unique marine ecoregions. These divisions are based on the distinct types of sea life found in each area.
Did you know that Quebec is the only province that touches two different ocean realms? It borders both the Arctic and the Temperate Northern Atlantic realms!
