Lake Simcoe, Ontario, is where a monster the locals call Igopogo (it is a play on the popular British Columbia Lake Monster, Ogopogo) supposedly dwells. Seen for more than a century, the creature is described as a large, “dog-faced” animal. Most often it is seen in Kempenfelt Bay, near Barrie. A believable videotape of Igopogo swimming at the southern end of the lake was taken in 1991 by unidentified visitors. It appeared to be a “relict seal,” according to one chronicler.
A similar Lake Monster in nearby Muskrat Lake, Ontario, was captured on film at about the same time by Dana Rogers. The unknown animal appeared to be at least ten feet long and swimming up and down like a seal, even though it was apparently not one. Muskrat Lake has hosted many sightings, including some of the creature (called Mussie or the Hapyxelor) on the shore. Michael Bradley wrote of the history of the encounters in More Than a Myth: The Search for the Monster of the Muskrat Lake (1989).
Both Lake Monsters are described as up to twenty feet long and gray. They resemble giant seals with strange heads.
