Ten years seems like a long time to not be aware that someone is living on your property. But if you are keeping up the taxes and maintenance on it, you shouldn't have to fight for it.

What gets me is all this "public land" owned by the crown that no-one is allowed to use until a developer is ready to make a profit on it.

This is kind of a weird thing to prioritize, in these times. I'm sure one of their supporters has a situation though.
