July 18 (UPI) — Ontario Premier Doug Ford on Saturday shot back at President Donald Trump, saying his comments about Canada’s efforts to control the ongoing wildfire crisis are a “shame” and “totally unacceptable.”

Trump threatened Friday to impose tariffs on Canadian imports and accused the country of “willful negligence” in its management of the blazes.

“I find it a shame, the administration in the U.S. and Congress people, writing these letters and blaming us,” Ford said in a press conference on Saturday. “They have a very short, short memory. We had the water bombers, everyone ready, going over to California — it was last year. We sent hydro linemen down to the Carolinas and Georgia to help out.”

Ford added, “That’s what neighbors do, right? You don’t get on and start threatening and criticizing because, guess what? One day it’s going to be your turn.”

As of Saturday, there were 959 active wildfires burning through Canada, 102 of which started in the past 24 hours, Canadian Interagency Forest Fire Centre reported.

The blazes have left more than 100 million Americans under air quality alerts, from Minnesota to Virginia.

“We are holding Canada responsible for the fact that they are not properly maintaining their Forests, and Brush therein, and the United States is being unnecessarily invaded by filthy, polluted, and unhealthy air, the quality of which is dangerous, and totally unacceptable!” Trump wrote on Truth Social.

Despite the dispute, Ford said Canadians would stand at the ready should Americans need support in the future.

“We’re going to be down there without hesitation to support our neighbors, which we should be,” he added.
