Ballot initiative in Alberta could undermine Canadian unity

It's being called Canada's "Brexit moment." Alberta's premier has just announced that a referendum will be held in October, asking voters in the province whether they wish to remain part of Canada, or begin the legal process of pursuing separation. UK-based environmental journalist Leana Hosea of Watershed Investigations is on a reporting trip in Alberta. She joins Host Marco Werman from Edmonton to discuss the origins of the movement, its legal status and why the possibility of secession puts the rights of First Nations communities in jeopardy.
