Toronto-area MP Michael Ma is crossing the floor to join Mark Carney’s Liberals.

In a statement issued on Thursday night, the MP for Markham-Unionville said he was inspired to leave the Conservative caucus after listening to his constituents.

“After listening carefully to the people of Markham–Unionville in recent weeks and reflecting with my family on the direction of our country, I have informed the Speaker and the Leader of the Opposition that I will be joining Prime Minister Mark Carney in the government caucus,” Ma said in a statement released by the Liberals.

“This is a time for unity and decisive action for Canada’s future,” Ma, who narrowly defeated the Liberal candidate in the 2025 federal election, added in the statement.
