I live in a medium sized city about 40 minutes west of Toronto. The laws here state that, even if the landlords policy prohibits pets, that a person can not be evicted for owning them and keeping them in their residence. Even if the aminal is a breach of city bi-law, they can only make you get rid of it if there is a complaint from a neighbour... and only the prohibited animal(s). You should check into it as my current building policy states "Absolutely no pets", yet my building has numerous cats, birds and a rather large Doberman Pincer that the owners flaunt proudly down the hallway several times per day on their way for walks!!
