OTTAWA — Ontario MP Marilyn Gladu says she has left the Conservative caucus to join Prime Minister Mark Carney’s Liberals.

In a statement, Carney said, “At this important moment for our country’s future, Canadians with a broad range of experience and perspectives are uniting to build Canada strong. I am honoured to welcome Marilyn Gladu today as the newest member of this government and our Liberal caucus. In a time of global economic uncertainty, Canada’s success will depend on how we build ambition into progress and strengths into sustained advantage. Marilyn brings the practical, results-driven leadership this effort demands. Having spent decades of her career in engineering and international business, she understands what it takes to create good jobs, strengthen supply chains, and ensure Canadian industry can compete in a rapidly changing global economy.”

In a statement posted on social media, Gladu says she believes this choice is the best thing for her community’s priorities and for the country.

Gladu has been elected as a Conservative four times in the Sarnia region.
