Central Canadian Shield forests
This ecoregion consists of rolling hills, lakes, bogs and rocky outcrops covering a large curved swathe on the Canadian Shield from eastern Manitoba and Northern Ontario running southeastwards through Thunder Bay District to the north shore of Lake Superior and then northeastwards into western Quebec. The area has a cool climate with summer temperatures averaging around 13°C dropping to a very cold -17°C in winter, with the hills around Lac Seul in northwestern Ontario being warmer and wetter than most of the area. Average rainfall in the eastern side of the ecoregion is 550mm per year, rising to 750mm in the centre (near Lake Nipigon for example), up to 900mm in the west. Specific areas include Lake Nipigon and Big Trout Lake (Ontario). These forest contrast with more severe boreal forest ecoregions such as the Eastern Canadian Shield taiga to the north, which covers most of Northern Quebec and Labrador.
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.
