I want to invite my parents to Canada on a supervisa. I am a permanent resident living in Toronto. I consulted an immigration agent recently and I was told that a supervisa has a re-entry restriction and that once Parents come in to Canada and stay for a certain length of time (say 1 year) they will have to leave and spend an equal amount of time outside Canada before re-entering. Is this true? I am not seeing any reference for this policy anywhere. Is there a minimum amount of time that visitors on a supervisa have to spend outside Canada before re-entering?
