Canada Warns US Against Halting Supply of Masks Amid COVID-19 Pandemic Steve Herman WHITE HOUSE - Canada is warning the administration of U.S. President Donald Trump about halting the supply of masks needed by first responders in the international battle against the coronavirus. "The level of integration between our economies goes both ways across the border," said Canadian Prime Minister Justin Trudeau on Friday. "It would be a mistake to create blockages or reduce the amount of back-and-forth trade of essential goods and services, including medical goods across our border. That is the point we're making to the American administration right now." Canada will "pull out all the stops" to prevent the United States from blocking the exports of some medical equipment, said Deputy Prime Minister Chrystia Freeland. The Trump administration Thursday invoked the Defense Production Act to require 3M, a Minnesota-based multinational conglomerate, to prioritize orders from the Federal Emergency Management Agency for N95 respirators. There are "significant humanitarian implications of ceasing respirator supplies to healthcare workers in Canada and Latin America, where we are a critical supplier of respirators," the company said in a statement Friday. "In addition, ceasing all export of respirators produced in the United States would likely cause other countries to retaliate and do the same, as some have already done. If that were to occur, the net number of respirators being made available to the United States would actually decrease." .
