Ontario Premier Doug Ford says the U.S. Supreme Court’s decision to reject many of U.S. President Donald Trump’s global tariffs represents “another important victory,” but he says the fight will continue.

Ford made the comment in a post on social media on Friday, hours after the U.S. Supreme Court ruled that Trump did not have the power to impose many of his tariffs under the International Emergency Economic Powers Act (IEEPA).

Trump declared a national emergency in order to use IEEPA to slap Canada, and other countries, with 35 per cent tariffs.

This, however, did not apply to goods compliant under the Canada-U.S.-Mexico Agreement (CUSMA) as well as the sector-specific imposed duties, like the ones seen on automobiles, lumber and metals.

“We need to watch how the White House reacts. We need to keep up the fight against tariffs on auto, steel, aluminum and forestry, which remain in place and continue to hurt our workers,” the premier wrote in a post on X.

“I won’t stop fighting until every last tariff against Canada is dropped so we can grow our economies and create jobs on both sides of the border.”

Ford said his government is prepared to do “whatever it takes” to protect not only the province, but the workers, families, and businesses living in Ontario.

Toronto Mayor Olivia Chow also indicated that “tariff or no tariff,” the city is working to diversify its local economy and pointed to its new partnerships in the film and television industry as an example.

“We are diversifying our approach so that tariff or no tariff, we have a stronger base. But most importantly, shopping and loving local, that campaign will continue,” Chow told reporters at an unrelated news conference Friday morning.
