OTTAWA—The federal and Ontario governments are hailing the first N95 masks to roll off a domestic assembly line as a step toward better pandemic protection for Canada now and into the future.

The masks are being produced by 3M Canada following a multimillion-dollar deal between Ottawa and Queen’s Park announced last August by Prime Minister Justin Trudeau and Ontario Premier Doug Ford.
