The leader of Ontario, Canada’s most populous province, on Wednesday triggered a snap election, saying he needs a strong four-year mandate to fight the tariffs threatened by U.S. President Donald Trump.

Ontario voters are set to head to the polls in a rare winter election. Premier Doug Ford has already been framing the snap election, coming right before an anticipated federal vote, as necessary for a strong mandate in order to best represent Ontario’s interests on the national and world stage.

Ontario Progressive Conservative Leader Doug Ford pitched himself Wednesday as the best steward of the economy in the face of looming tariffs, but the other party leaders say his record from the last seven years suggests otherwise.
