Canada still allows squatting rights in some cases, it really depends on the situation, where, and for how long has the spot been squatted. It's a very old fashion ideal. If you lived somewhere long enough and controlled that place, after enough time it's considered yours. Sadly, some homeless people were using squatting rights because they could prove they lived in an abandoned building long that building is legally theirs, and they won it. So, the laws have changed quite a bit.
