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 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.

Due to Trump’s tariffs, Canada cannot afford to have the focus of one of its key provincial leaders diverted into trying to win an unnecessary provincial election.
