Conservative MP Defects to Join Liberal Party

In a significant political shift, Ontario MP Michael Ma has defected from the Conservative Party to join the Liberal Party. This announcement was made on December 11, 2025, during a statement from Ma regarding his decision.

Reasons Behind the Defection

Michael Ma cited a desire for unity and decisive action as key factors in his decision. Representing the riding of Markham-Unionville in the Greater Toronto Area, he emphasized the importance of aligning with the priorities of his constituents. In his statement, he expressed support for Prime Minister Mark Carney, stating that Carney provides the steady leadership needed for the country’s future.

Political Context

This shift follows a recent trend of Conservatives leaving the party. Just weeks prior, former Conservative Chris d’Entremont made a similar move to join the Liberal government. Ma’s decision further solidifies the Liberal Party’s position, bringing them closer to a majority in Parliament.

Impact on the Liberal Party

• Ma joins the Liberal caucus as the party moves closer to a majority government.
• This defection highlights the growing appeal of the Liberals in the current political landscape.

Michael Ma’s departure from the Conservatives signals a potential shift in voter alignment in Ontario. Many are watching closely to see how this will affect future elections and policy discussions.
