Again, I'll add the caveat that I'm not involved in the direct procurement of vaccines, so I'm probably not the best person to ask about all of that.
As of now, Canada has an arrangement with AstraZeneca to provide 20 million doses. We are watching very carefully and engaging with the federal government in the United States. Our expectation is that this will be upheld, but as it is an extremely important and serious issue for all Canadians, we need to continue to be engaged.
