Ford said electricity, critical minerals, and fuel exports to the US could be leveraged.

Donald Trump also ramped up his rhetoric, threatening additional tariffs starting next year.

Canadians aren't playing around.

Doug Ford, premier of Ontario, Canada's most populous province, says Canada is willing to go much further in the escalating trade war with the US than President Donald Trump realizes.

"We can put massive pain on the US," Ford told reporters during a searing press conference on Monday.

"President Trump underestimates us, and that's the biggest mistake: underestimating your opponent." If the trade war continues to ramp up, Ford said "everything's on the table," including electricity, critical minerals, and fuel.

He added that Canadian premiers, who lead Canada's 10 provinces, needed to work together to put pressure on the US.

"We need everyone to be on Team Canada and throw everything and the kitchen sink at them," he said.

Trump's latest round of tariffs on Canada took effect on Saturday after talks between the North American allies fell through.

The tariffs impact a range of Canadian goods, from alcohol and hockey equipment to paper and construction materials.

Canada supplies electricity to the US via cross-border transmission lines.

In 2025, Canada exported $3.3 billion worth of electricity to the US, according to Canadian government figures.
