The eastern timber wolf was at one time found as far south as Florida and as far west as Minnesota. It still occupies over 40% of its original range in Canada. However, it is found mainly around the Great Lakes and St. Lawrence regions of southeast Ontario and southwest Quebec in remote, forested areas. Their greatest concentration is in Algonquin Park in Ontario.
The eastern timber wolf does not always make use of shelters except when rearing offspring. Their shelters will always be near a water source. The territory of their pack may cover anywhere from 20 to 120 square miles.
