Canadian Mind-Boggling Facts
Three Million Lakes, Canada has a lot of great things in abundance, like hockey players, parkas and Tim Hortons franchises. But did you know we also have more lake area than every other country in the world? It's true. The Great White North has 563 lakes larger than 100 square kilometres. The Great Lakes alone contain about 18 per cent of the world's fresh lake water. That's a lot of water. Makes you wonder if all of our country's allies are actually just thirsty.
