President Trump says he’s suspended trade talks with Canada over an advertisement produced by the government of Ontario that criticizes tariffs. The ad features excerpts of a 1987 address by then-President Ronald Reagan warning of the dire consequences of high tariffs, like the 35% tariff Trump has imposed on most Canadian goods not covered under a trade agreement.

President Ronald Reagan: “High tariffs inevitably lead to retaliation by foreign countries and the triggering of fierce trade wars. Then the worst happens. Markets shrink and collapse. Businesses and industries shut down, and millions of people lose their jobs.”

In a social media post, Trump lashed out at the one-minute ad, calling it ”FAKE,” writing, “Based on their egregious behavior, ALL TRADE NEGOTIATIONS WITH CANADA ARE HEREBY TERMINATED.”
