On April 28, 2025, Conservative Leader Pierre Poilievre faced the challenge of U.S. President Donald Trump’s interference in Canadian politics as he cast his vote in the federal election. Trump suggested Canadians should consider voting to become the 51st state, which allowed Liberal Leader Mark Carney to campaign on the promise of effectively handling U.S. relations. Poilievre, who has spent over two decades in Parliament and became Conservative leader in 2022, emphasized Canadian sovereignty and the importance of voters choosing their future, while awaiting the election outcome.
