Since 2005, Canada has been marrying same-sex couples — many of them people from foreign countries who flocked to the Great White North just to wed. But now, the Canadian government has said that those who came from other countries where same-sex marriage is illegal and married in Canada are not legally married. The revelation of the apparent about-face came with government filings in a divorce case filed by a lesbian couple, an American and a Briton, who married in Toronto, The Globe and Mail reported Thursday. According to the CBC, the couple's situation was complicated because although Canadian marriage laws didn't require residency, its divorce laws did — meaning couples who married there might be unable to divorce. Activists fear the government's position on foreigners' marriages is an attempt to roll back gay rights, but Prime Minister Stephen Harper insisted his administration is not trying to reopen the issue.
