Terrestrial ecoregions of Canada The following is a list of ecoregions  in Canada   as identified by the World Wide Fund for Nature  (WWF).
Terrestrial ecoregions 
The terrestrial ecoregions  of Canada are all within the Nearctic realm , which includes most of North America . The Nearctic, together with Eurasia's Palearctic realm , constitutes the Holarctic realm  of the Northern Hemisphere .[ 1] 
British Columbia  is the most biodiverse  province with 18 ecoregions across 4 biomes. By contrast, Prince Edward Island  is the least biodiverse with just one ecoregion - the Gulf of St. Lawrence lowland forests  - encompassing the entire province.

Marine ecoregions 
Canada is unique among countries in that it borders three marine realms : the Arctic , Temperate Northern Atlantic , and Temperate Northern Pacific . These realms can be further subdivided into three marine biomes  and fifteen marine ecoregions  based upon biological distinctiveness.[ 2] 
Quebec  is the only province that borders both the Arctic and Temperate Northern Atlantic realms.
