Donald Trump has announced a 10% increase in US tariffs on goods imported from Canada following an anti-tariff advertisement broadcast in Ontario that featured Ronald Reagan. Describing the advert as a fraud, Trump criticized Canadian officials for not removing it ahead of the World Series baseball championship.

In a statement, Canadian Prime Minister Jay Carney acknowledged the tensions but expressed readiness to continue building on prior trade negotiations. He highlighted that Canada is exploring trade relationships with other nations, given its unique position as the only G7 nation without a recent trade agreement with the US amidst Trump’s tariff initiatives.

The US currently imposes a 35% tariff on a range of Canadian goods, with many articles exempt due to pre-established free trade agreements. Trump indicated that the new tariff would apply above preexisting rates, impacting primarily industries critical to Canadian exports, especially in Ontario, which is key to Canada's automobile production.

Carney remarked on the importance of seeking advantageous agreements for Canadian workers, stating, It's the sole responsibility of the government of Canada to have discussions with the United States and it's the best way forward. He also assured Canadians that a comprehensive budget would soon be released, aiming for substantial investments while emphasizing the need to diversify trade relationships.

The announcement has triggered mixed reactions; the Canadian Chamber of Commerce hopes diplomatic negotiations can resolve the impending trade escalation. They characterized tariffs as detrimental to overall North American competitiveness.

The contentious advertisement, sponsored by the Ontario government, was intended to highlight the economic impact of tariffs by featuring Reagan's views against them and has faced criticism from the Ronald Reagan Foundation for its selective use of content. Despite an agreement to pause the advertising campaign for trade discussions, the advert aired during the World Series, prompting Trump's reaction that it should have been retracted immediately.

The exchange between Ontario's Premier Doug Ford and California Governor Gavin Newsom, jokingly referencing tariffs within the context of World Series bets, reflects the complex interplay of trade, politics, and regional camaraderie amidst current trade disputes.
