Southern Ontario
Southern Ontario has a very different climate from the rest of the country. It is the only area of Canada that has Carolinian forest. Many trees, plants, and wildlife in Southern Ontario are not found anywhere else in Canada. Some rare trees to Canada in this region include the tulip tree, pawpaw fruit tree and the cucumber tree. The Carolinian forests of Southern Ontario have in large part been destroyed by development sprawl. Very few original growth areas remain.

A report issued in 2011 by the Pew Environment Group described the Canadian boreal forest as the largest natural storage of freshwater in the world.
