I wonder if Mormons allowed to have multiple wives in Canada?
If you read the whole article you will find that neither Mormons nor Muslims can have more than one wife here. There is some ambiguity in the law related to the recognition of foreign marriages by the feds and the province, but no such ambiguity exists in the case of Mormons because Ontario only recognizes marriages that were legal in the country where they took place. Last time I checked, polygamy was illegal in the USA.
Further on this, it appears that the Ontario law recognizing polygamous foreign marriages applies to divorce law. That means a Muslim with more than one wife can be sued for divorce and alimony by all of them.
