This list compiles many of the common large shrubs and trees found in Canada. The Canadian flora is depauperate because of the near total glaciation event in the Pleistocene. Due to the vast area of Canada, a tree that is common in one area may be completely absent in another. In particular, many warm-temperate trees can only be grown on the mild Pacific coast (where gardens may contain additional species not listed here). See also Provincial tree emblems of Canada for the official trees of the Provinces and Territories of Canada.
