Because of its "rich fertile soils", relatively mild climate, and extensive waterways, the Mixedwood Plains Ecozone, is one of the "most productive ecozones in Canada". The ecozone extends along the St. Lawrence shoreline to Quebec City. It represents the "most populous and prosperous terrestrial ecozone". and is home to nearly half of Canada's population, including its two largest cities, Toronto, Ontario and Montreal, Quebec.
