Thank you very much for that, Dr. Wong-Rieger. On behalf of Canadians, you are very insightful.
Ms. Berg, if I can, I'll turn to you. I think we have a little under a minute left.
You talked about supply chains in Canada. From the list of medications we have seen, it appears that with some medications—let's just pick metformin, which is incredibly common—there's a suggestion that there may only be a single-source supplier.
Can you tell us a bit about how that may be a problem for Canadians with respect to drug shortages?
