OTTAWA — Conservative MP Marilyn Gladu announced her decision to cross the floor to the Liberals on Wednesday, becoming the fourth Conservative to cross to the governing party in recent months.

“This past year has been like no other that Canada has ever faced, and I’ve heard clearly from constituents that you want serious leadership and a real plan to bring a stronger and more independent Canadian economy,” said Gladu, in a statement.

“That is why I have decided to join Prime Minister Mark Carney and Canada’s new government as the newest member of his caucus.”

In a statement on Wednesday, Carney said he looks forward to working with Gladu.

“In a time of global economic uncertainty, Canada’s success will depend on how we build ambition into progress and strengths into sustained advantage,” he said. “Marilyn brings the practical, results-driven leadership this effort demands.”

The Liberal government has secured five floor crossers in recent months, four from the Conservatives and one from the NDP, when Nunavut MP Lori Idlout crossed last month.

Gladu has represented the riding of Sarnia—Lambton–Bkejwanong since 2015 and she won her seat handily in the 2025 election with 53.1 per cent of the popular vote.

More to come.
