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.
Ontario tobacco belt
Should the sea levels rise by , the Ontario tobacco belt would not be affected by flooding. However, it may be affected by droughts as a by-product of the dislocation of available fresh water and may be forced to rely on desalinated salt water piped in from the Eastern United States. Constructing the proper infrastructure to carry the water hundreds of miles away would take considerable manpower along with significant economic costs and an unprecedented level of cooperation from multiple federal, state/provincial, and municipal governments. Another possible outcome of the global climate change would bring back desertification into the Lake Erie portion of the tobacco belt. Any grasslands in the area would become brown and eventually become sand; increasing in dryness the further the piece of land is from a source of fresh water. A regional bout of famine would occur if the desertification continued to spread inland and threatened the local crops.
