Trudeau calls byelections in Outremont, two other ridings for Feb. 25

Prime Minister Justin Trudeau has set Feb. 25 as the date for byelections in three vacant ridings — including the British Columbia riding where NDP Leader Jagmeet Singh is hoping to win a seat in the House of Commons.

Trudeau has called the byelections for Burnaby South, Montreal's Outremont riding and the Ontario riding of York-Simcoe.

The byelections will be a crucial test for New Democrats, who've been struggling to find their footing since their party was relegated to a distant third in the 2015 general election.

But the race in Outremont, left vacant after former NDP leader — and current CJAD 800 political commentator — Tom Mulcair resigned, will also be seen as a test of whether the NDP can hang on what's left of the orange wave that swept Quebec in 2011.

The Conservatives are expected to easily keep York-Simcoe, left vacant by the resignation of long-time Tory MP Peter Van Loan.

Trudeau has not called a byelection in another B.C. riding, Nanaimo-Ladysmith, vacated last week by New Democrat MP Sheila Malcolmson, who is seeking a seat in the provincial legislature.
