Ishpatina Ridge is the highest point of land in the Canadian province of Ontario, at an estimated 693 m (2,274 ft) above sea level.

It was only truly recognized as Ontario's highest point after topographical mapping by the Government of Canada revealed this fact in the 1970s.

The most popular approach route to Ishpatina is by canoe/portage via a logging road to the south out of the town of Capreol north of Sudbury.

Historically, a fire tower atop the ridge was staffed by forest workers and they would have been ferried to the site by float plane.

[5] An abandoned firetower, often referred to as the Ellis Tower, is still standing on the highest section of the Ridge (left).
