Thank you, Mr. Chair.
Thank you to all the witnesses today.
Mr. Ahmed, that was a really interesting presentation, with very important issues being raised, obviously. I take your point, and I agree with you that where the government has acted, it needs to be acknowledged that it's done a lot, a great deal, over the past few months, especially to ensure that we have an adequate supply of PPE going forward and that we also have facilities being supported in Canada to produce vaccines well into the future. Clearly, we're going to see something materialize in Quebec in August of this year, but we've also seen a number of announcements that are really critical as far as securing the long term.
The question I want to put to you, though, is about critical drug shortages. How concerned are you, and as a way of getting to that question, can you define what we're actually talking about when we talk about critical drugs, just so that we're on the same page?
