TORONTO — Prime Minister Justin Trudeau said he’s confident that Canada will be able to import N95 protective masks form the U.S. despite an export ban and plans to speak to U.S. President Donald Trump in the coming days, he said.

Trump has said he will block exports of the masks from the United States to ensure they are available for domestic use during the coronavirus pandemic.

Meanwhile, the premier of Newfoundland and Labrador, the Canadian province that sheltered thousands of stranded Americans after the 9/11 attacks, expressed disbelief that Trump would even think of barring the masks’ export to Canada, saying this is a time to work together, no matter the passport.

Premier Dwight Ball said a central lesson for humanity is that in times of crisis you don’t stop being human, as his province demonstrated in 2001, when, after the terrorist attacks on the World Trade Center and the Pentagon resulted in the sudden grounding of air traffic, more than 6,600 passengers descended without warning on Gander, Newfoundland, a town of 10,000. Canadians took care of them. The premier emphasized that his province would do it again.

Trudeau noted that Canada supplies the U.S. with many related goods including pulp for surgical-grade N95 masks, test kits and gloves. Canadian nurses also work in the U.S.

Trudeau said it would be harmful to both nations if the flow of those goods and services stopped.

Manufacturing giant 3M MMM, +1.69% said there are significant humanitarian implications in not sending N95 masks to health-care workers in Canada and Latin America, where the Minnesota company, a component of the Dow Jones Industrial Average DJIA, -0.46% , is a critical supplier of respirators.

Trump has said that the U.S. wants the masks and that he doesn’t want others getting them.
