There are 1978 named mountains in Ontario. Ishpatina Ridge is the highest and the most prominent mountain.Covering more than 415,000 square miles, Ontario is Canada’s second largest province in total area. The province is bordered by Manitoba to the west, the Hudson Bay and James Bay to the north, Quebec to the east and northeast, and several U.S. states to the south. Almost the entire U.S./Ontario border follows inland waterways, including Lake of the Woods, which is fed by the Rainy River, Shoal Lake, Kakagi Lake, and several other small rivers, and the Great Lakes/Saint Lawrence River drainage system, which includes several major rivers and lakes like Lake Superior, Lake Huron, Lake Ontario, and the St. Lawrence River.

Ontario Mountains

Generally, Ontario is divided into two regions: Northern Ontario and Southern Ontario. Northern Ontario, the larger of the two regions, is sparsely populated, while the southern region houses the majority of Ontario’s population. Northern Ontario covers approximately 350,000 square miles and is known for its incredible lakes, rivers, and densely forested, rugged terrain. Southern Ontario consists mostly of gentle relief, its highest point reaching just over 1,700 feet in the Blue Mountains.

Despite containing over 800 named mountains, Ontario does not include significant mountainous terrain and its highest point, Ishpatina Ridge, reaches just over 2,200 feet above sea level. Large areas of the uplands, however, particularly within the Canadian Shield, contain several impressive peaks. The average elevation in the Canadian Shield region is 1,000 feet, though several high hills and ridges north of Sault Ste. Marie exceed 2,100 feet. Most of Ontario’s most striking summits and rugged wilderness areas can be found bordering the Great Lakes on the southern fringes of the Canadian Shield.
