MONTREAL — Alexandre Boulerice, the federal MP for the Montreal riding of Rosemont—La Petite-Patrie, is expected to make an announcement about his political future on Monday.

A source within Québec solidaire suggests Boulerice plans to leave the NDP and run provincially with Québec solidaire in Gouin, a provincial riding located in Montreal.

He could aim to replace Gabriel Nadeau-Dubois, former co-spokesperson for Québec solidaire, who has said he will leave politics at the end of his mandate.

Boulerice’s exit would leave the NDP with no MPs in Quebec and just five seats, all west of Ontario.

The last remaining Quebec MP from Jack Layton’s 2011 “Orange Wave,” Boulerice has voiced frustrations with the New Democratic Party, including disappointment over the role of French in the leadership race,

Ahead of Avi Lewis’ NDP leadership win, Boulerice said a move to Québec solidaire was under serious consideration, despite calls for him to stay in the NDP.
