The U.S. president’s trade war and threats to make Canada the 51st state have infuriated Canadians and led to a surge in nationalism that has helped the Liberal Party flip the narrative.

The elections come against the backdrop of Donald Trump threatening to make Canada their 51st state, and the resignation of former PM Justin Trudeau.

Canadians vote on April 28 to elect a new prime minister. The key contenders are Mark Carney (Liberal) focusing on economic reform and government action, and Pierre Poilievre (Conservative) pushing for deregulation and tougher crime policies.
