The Mark Carney Liberal government has achieved a majority government, secured by winning three by-elections this evening.

The two ridings in Ontario and one in Quebec have pushed the number of Liberal seats to 174.

Inching toward a majority was also augmented by accepting five MPs from Opposition parties as floor-crossers (four from the Conservatives and one from the NDP) since November.

Order of wins:

The win in University-Rosedale was declared early by national media (based on Elections Canada numbers), and soon thereafter the win in Scarborough Southwest was declared.

Watching Terrebonne incoming results all evening was not unexpectedly a close race.

Terrebonne was won in April 2025 by one vote (though that result was annulled by the Supreme Court due to Elections Canada special mail ballot envelope errors).
