Ouimet Canyon is a large gorge in the Canadian province of Ontario, about 60 kilometres northeast of Thunder Bay in Dorion Township. The gorge is 100 metres (330 ft) deep, 150 metres (490 ft) wide and 2 kilometres in length, protected in the Ouimet Canyon Provincial Park.
There is a walkway consisting of boardwalks and trails, which leads to viewing platforms overlooking the canyon. Visitors to the canyon should remain on the marked trails for their own safety. Also in the Ouimet Canyon area, there are rare alpine flowers that are considered especially beautiful and arctic plants normally found 1000 km further north.
