Thank you very much, Mr. Chair.
Ms. Elmslie, I want to thank you for hitting the nail on the head there. It's the evolution of science. That explains so much. From day one, this has been a rapidly evolving situation. I know that all of the people who are taking care of Canadians and watching over the health and safety of Canadians are constantly monitoring new data every day as it arrives.
I think we all agree, on this committee, that we have to do everything we can to protect Canadians from COVID, especially with these new variants. One new case of COVID is too many. I want to thank all the witnesses today for the work that you do, every day, because I suspect that you live this. You live this, and you have for probably a year.
You didn't get a chance to answer all the questions that were asked of you. Members are very tight with time. We have a lot of constraints on the time here and you didn't get a chance to answer all the questions you were asked. You specifically mentioned the importance of a multi-layered approach to controlling and preventing COVID-19.
Since I'm on with you, Ms. Elmslie, I wonder if you could elaborate on this multi-layered approach on how we need to take every step to make sure we ensure the safety of Canadians.
