ABOARD AIR FORCE ONE (AP) — President Donald Trump said on Saturday that he plans to hike tariffs on imports of Canadian goods by an extra 10% because of an anti-tariff television ad aired by the province of Ontario.

President Donald Trump said he's terminating trade negotiations with Canada citing a negative TV advertisement about tariffs.

An Ontario government ad that attracted the wrath of U.S. President Donald Trump was successful — even if it didn’t produce the outcome provincial officials might have anticipated, say experts in political communication.

The speech on tariffs from President Ronald Reagan that the Ontario government used in a $75 million ad blitz did omit a key section that calls into question the thrust of the message.

General Motors Co. and Stellantis NV will be forced to pay tariffs on some US-made vehicles they import for sale in Canada, after the companies decided to reduce assembly-line work at factories in Ontario.

Finance Minister Peter Bethlenfalvy says the fiscal update will be a plan to make the province's economy competitive and protect jobs.
