Quebec's Manicouagan Crater is one of the largest fairly well-preserved impact craters on Earth.  A ring-shaped hydroelectric reservoir lake 70 km in diameter occupies the centre of the crater. The impact that formed the crater happened about 210 million years ago and may have played a role in the mass extinction of species that occurred about the same time.

I wish to nominate Canada's own Manicouagan Meteorite Crater in northern Quebec. It is the largest preserved impact crater on Earth. It was created some 214 million years ago, and is truly a significant natural wonder if there ever was one. So big and distinct, it can actually be see from space. Truly unique and of course, truly Canadian.
