that's odd, where I live in Ontario, you can be legally separated as soon as the partner leaves, you must be legally separated for at least 1 year to file for divorce, with no breaks where the partner moves back in for any period of time. The exception to this is adultry where you then do not have to wait a full year to get divorced.
