NDP leader says he won’t run in Quebec byelection as Boulerice announces departure

“It’s not a decision that is taken lightly,” he said. “After 15 years and five election victories, I felt I had done what I needed to do in Ottawa and that it was now time to come back home, here, to Quebec.”

His departure is another blow to the NDP, which last year had its worst showing in a federal election, winning just seven seats. It needs 12 to be considered an official party in the House of Commons, which means it no longer has a seat on House committees, and had its caucus funding reduced.

The NDP caucus was reduced to six in March when Nunavut MP Lori Idlout crossed the floor to the Liberals.

Boulerice’s departure will cut that further to five. He was also the only MP in Quebec, and the only one east of Manitoba.

Lewis, who was elected less than a month ago to lead the party, said he encouraged Boulerice to stay on in Parliament.

“I think everyone did and when I saw Alex in my first moments as leader, I did what I think a responsible leader should do because everyone had heard the rumours for a long time and we knew he was considering it,” Lewis told reporters Monday.

“But it’s clear that this decision has been a long time in coming and we were ready.”

Although Lewis doesn’t hold a seat in the House of Commons, he said he won’t run in the vacated seat because Quebecers should be represented by someone from Quebec and it’s too soon for him to consider a run.

“This is not a riding where I will seek election myself,” he said. “I’m not a Quebecer, and there’s a lot of interest already locally.”

Boulerice said his shift to provincial politics reflects where he believes the most urgent battles are now being fought in Quebec.

“The house is not in order,” he said. “We need to fix Quebec.”

He said issues like housing affordability, public services and inequality have become increasingly difficult to address from Ottawa, and stronger provincial action is required to respond to what he described as mounting social pressures in Quebec.

Lewis said Monday he believes Boulerice’s move is different from recent floor-crossings and what he called “opportunistic moves that we’ve seen from MPs recently.”

In addition to Idlout, four MPs elected as Conservatives joined the Liberals between November and April.

“This is a move of principle,” said Lewis. “Alexandre wants to put his considerable skills as a politician and as a fighter for progressive values to work in his province, and we respect that decision.”
