Thank you, Mr. Chair.
For the benefit of my friend Mr. Davies, I'll start again.
Dr. Liu, you have considerable first-hand experience in dealing with epidemics. Before asking you some more specific questions, I want to express my sincere appreciation for your presentation and your proposals. Public health is probably the most policy-oriented field of medicine. We're talking about public health policy. Since the start of this pandemic, I've suspected that it sometimes stands in the way of what should be done.
I want to know your overall assessment. Only a month ago, the Canadian borders were still open, and Canada considered that its citizens faced a very low level of risk. We now know, a month later, that the United States is the largest source of infection in the world.
Perhaps in public health, we're facing a low level of risk. However, it's a matter of concept and vocabulary. There are still deaths.
What should we have done differently? How would you assess our preparation for the first wave? The second wave could be the deadliest.
