Why are "no pet" clauses legal in the US but not in Toronto? At least according to this site, in Toronto you can't disallow pets.
I started thinking of it and its actually a little absurd. Trying to apply the same reasoning to other things. Like disallowing musicians, when really you just don't want noise to bother other tenants. Disallowing frat students because you think they ruin your apartment and bother neighbors. Disallowing X because you believe it will cause Y instead of just disallowing Y.
They are not perfect analogies, but I think the main reason people disallow pets is for damages, and maybe noise. Isn't this discrimination against pet owners?
