Sturgeon Lake in Northwestern Ontario is a massive, cold, and deep Canadian Shield lake located northeast of the town of Ignace, accessible via Highway 599. Stretching approximately 55 miles long with a width of about 6 miles at its widest point and a perimeter of roughly 399 miles, this is a serious body of water that demands respect and preparation. With an average depth of 44.5 feet and a maximum depth exceeding 300 feet — the deepest hole plunging to over 305 feet — Sturgeon Lake ranks among the premier lake trout habitat lakes in all of Ontario. The lake sits on the Canadian Shield, giving it the characteristic rocky structure, clear water, and cold temperatures that define world-class cold-water fisheries. Beyond its legendary lake trout fishery, Sturgeon Lake has undergone a remarkable walleye rehabilitation that has transformed it into one of the top multi-species destinations in Northwestern Ontario. The lake carries a rich history tied to the fur trade, with both the Hudson Bay Company and the Northwest Company once operating posts on its shores, and its name is believed to derive from the Sturgeon Cree Indians of Nipigon who used the lake as a travel corridor to Fort Albany.
