Canada will recognize a foreign divorce if it was validly granted in a foreign country as long as one of the former spouses was ordinarily a resident in that country for at least a year before the divorce proceedings were started there.
If you are seeking a marriage licence in Ontario and you have been divorced in a foreign country, you must obtain an opinion letter from a lawyer giving reasons why the divorce or annulment should be recognized in the Province of Ontario.
I charge a flat fee of $400, inclusive of HST for this service. I will need an original or court-certified copy of your divorce decree or annulment. Email me to set up an appointment: David@drusslaw.com.
