* President Donald Trump threatened to impose **100% tariffs on all Canadian exports to the US** if Canada makes (or follows through on) a trade deal with China.
* Trump mocked Prime Minister Mark Carney as **“Governor Carney”** and argued Canada was wrong to open itself to more Chinese business, including increased access for Chinese electric vehicles.
* The threat comes after a **Canada–China agreement** aimed at lowering trade barriers and rebuilding ties: Carney said Canada would allow **up to 49,000 Chinese EVs** at roughly a **6% (6.1%) tariff**, rolling back the prior **100% EV tariff/surtax**, while China would ease tariffs affecting Canadian agriculture (including canola/rapeseed) and offer **visa-free travel** for Canadians.
* The dispute is part of a broader, escalating feud tied to Davos and Greenland: Carney warned about coercion by great powers and argued that “economic integration” can be used as **weapons** (tariffs/finance/supply chains), while Trump responded by saying Canada “lives because of the United States” and withdrew Canada’s invitation to his **“Board of Peace.”**
* Trump also claimed Canada opposes his planned **“Golden Dome”** missile-defense project linked to Greenland, while the article notes it’s unclear whether that’s actually Ottawa’s position; Treasury Secretary Scott Bessent said Trump invited Canada to participate.
* It's uncertain what would meet Trump’s threshold for a “deal,” and what the threat would mean for trade under **USMCA**, where many goods are typically tariff-free; it notes a **35%** tariff for “non-excluded” goods, with sector variations (including steel, aluminum, and autos).
