Ontario Premier Doug Ford is standing by his decision to run an anti-tariff U.S. ad campaign after President Donald Trump halted trade talks with Canada because of it.

Ontario Premier Doug Ford says the province will “pause” its U.S. advertising campaign on tariffs as of Monday so that trade talks can resume after U.S. President Donald Trump broke off trade negotiations with Canada over the ads.

Ontario Premier Doug Ford said on Friday that the anti-tariffs advertisement featuring former President Reagan, which angered President Trump, will air during the World Series before being paused

Ontario Premier Doug Ford said he will pull a controversial anti-tariff ad Monday, after it airs during the weekend’s World Series games. U.S. President Donald Trump attacked the ad by the Ontario government, which uses quotes by former U.S. president Ronald Reagan to extol the virtues of free trade.

The premier of Canada’s most powerful province — and arguably the country’s most successful politician today — has gotten under Donald Trump’s skin again.
