Ontario Premier Doug Ford publicly rebuked U.S. President Donald Trump's threat to impose new tariffs on Canadian goods [1, 2].

The dispute signals a deepening rift in North American trade relations, as the U.S. administration links trade penalties to environmental issues like wildfire smoke.

President Trump announced a new tariff regime set to begin on Jan. 1, 2027 [1]. The measures target Canadian imports, including lumber, in response to smoke from Canadian wildfires drifting into the U.S. [2, 5].

Ford responded to the threats during press briefings in Toronto between June and July [3, 4]. He described the proposed tariffs as "rubbish" and said they were "driving me crazy" [2].

In a June 2 statement, Ford criticized the direction of U.S. trade policy by invoking a former president [3]. "Ronald Reagan would be 'throwing up' over your trade policies and would be 'disgusted' with you," Ford said [3].

While Ford suggested that removing existing lumber tariffs might help resolve the tension [5], he also signaled a willingness to escalate the conflict [1]. Ford warned that the trade dispute could expand to include Ontario's electricity exports, and critical minerals [1].

The tension follows rhetoric from the White House regarding Canada's status, including comments about Canada becoming a 51st state [3].

Ford said that the U.S. cannot simply dismiss the importance of the Canadian partnership. He characterized the idea that the U.S. does not need Canada as "bullshit" [1].

"These tariff threats are rubbish and they're driving me crazy."

The escalation between Ontario and the U.S. executive branch highlights a shift toward using non-trade issues, such as environmental externalities, as leverage for economic penalties. By threatening to restrict electricity and critical minerals, Ford is signaling that Canada may move beyond traditional trade litigation to use strategic resource dependencies as a counter-weight to U.S. tariff pressure.
