This in only Quebec AFAIK. But FWIW, Canada in general is pretty progressive that way. While actual marriage exists for those that want to, there's no reason to marry just because of tax advantages as there is in other countries. After a relatively short amount of time (a year or something like that) you can apply for a "common-law marriage" status and you basically get all the same things as if you were married.
