The father and son on opposite sides of Alberta’s separation vote

On Monday, people in Alberta will cast their ballots in a vote that includes a question on whether the western province should remain in Canada or pursue a binding provincial referendum on separation.

The other questions on the ballot paper ask Albertans about options to gain more autonomy from Ottawa, including on matters such as immigration control and access to social services for non-permanent residents.

In the separation vote, the remain side is expected to win, but the debate has caused tensions in Alberta. The BBC’s Nadine Yousif travelled to Buck Lake to speak with the close-knit Pietsch family, who have a father and son on either side of the debate.
