Same-couples in New Brunswick and the Northwest Territories (NWT) are the latest to challenge the traditional definition of marriage in Canada.
The New Brunswickers went to court Apr 25, while a couple in Yellowknife is expected in court on May 27.
If the New Brunswick and NWT couples win, same-sex marriage will be legal in all but three provinces and territories across the country, with only Alberta, Prince Edward Island and Nunavut still holding out.
