With an election call imminent, Canada’s political leaders are preparing for a high-stakes campaign centered on the country’s response to a trade war with the U.S. Prime Minister Mark Carney is expected to formally dissolve Parliament tomorrow, setting up a vote for late April or early May.

The election will take place against the backdrop of U.S. President Donald Trump’s aggressive trade policies, including steep tariffs on Canadian goods. Canada has responded with retaliatory tariffs, making the key ballot question which party leader—Carney, NDP’s Jagmeet Singh, or Conservative leader Pierre Poilievre—is best equipped to handle the escalating tensions.

Carney’s recent appointment as prime minister following Justin Trudeau’s resignation, along with Trump’s return to the White House, has reshaped Canada’s political landscape, erasing the Conservatives’ once-commanding lead in the polls.
