I live in kitchener/waterloo ontario and I just learned something recently. Apparently, you cant get kicked out of an apartment if you have a pet. Of any kind. Unless somebody complains (ie neighbours, or passers by) they cant legally do anything. The landlord might try and fake something if they dont like pets, but legally you cant be kicked out. So if you fight it then you will probably win. However, it sounds like it would be easier to just find somewhere that doesn't mind you having pets. Now this is only where I live. I have no idea of any other laws anywhere else.
