Perhaps I'll start and then go over to my colleague to talk about what has happened with Quebec, in particular.
Just to be clear, those masks that expired were purchased in 2009. They expired five years afterwards, in 2014, and they were destroyed in 2019, well before we had any inkling that this would be coming upon us. What we have done is to retain some other expired stock much more recently.
Health Canada, in an emergency, can often actually give you the authority to use expired materials. They still have to be subjected to a verification to make sure they do not pose any risk to the end-user. For anything that we did have, as well, we talked to our provinces and territories that also had expired stock. Where we were able to get the authority from Health Canada to use expired product, subject to a visual inspection, we did.
