3M faces pressure from Trump order to stop exporting N95 masks to Canada (cbc.ca)

I'm pretty sure this was directed at all exports. They were caught sending masks to China and other countries that were willing to pay a premium. This isn't a Canadian thing.

The USA sends billions in disaster relief around the world every year. At the moment they have an emergency situation where there is no spare capacity to supply PPE to other countries.

An unfortunate situation but completely understandable.

> "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. That is the opposite of what we and the administration, on behalf of the American people, both seek."
