Conservative Leader Pierre Poilievre has confirmed he will ask the other opposition parties to bring down the Liberal government next week with a non-confidence motion.
A Conservative spokesperson said the motion will simply say the House has no confidence in Prime Minister Justin Trudeau and his government.
Now that the NDP has ended the supply-and-confidence deal with the Liberals, the minority government needs to shore up support from opposition parties on a vote-by-vote basis.
The Conservatives will likely need the support of both the NDP and the Bloc Québécois for the non-confidence motion to pass.
The NDP haven't signalled which way they will vote on the motion, which will be debated next Tuesday and voted on Wednesday.
A spokesperson for the Bloc says the party will wait to see the wording of the motion before deciding how to vote.
Liberal House Leader Karina Gould says it will be up to Singh to decide if he wants to play into Poilievre's hands.
