TRENTON, Canada 

It would be a “mistake” for the United States to stop masks badly needed by health care professionals from coming into Canada, Prime Minister Justin Trudeau said Friday.

Trudeau was reacting to the Trump administration order to 3M to stop exporting the essential supplies to Canada.

He noted that thousands of Canadian nurses cross the border from Windsor, Ontario into Detroit to work at American hospitals. Goods and services are a two-way street between Canada and the U.S.

“The U.S. also receives essential supplies and products and indeed health care professionals from Canada every single day,” Trudeau said.
