Given your two hats, I think you're a good person to answer this question. It would seem to me that in Canada we're becoming two countries in terms of COVID-19. There are places like Thunder Bay, and I would suggest vast areas of Canada, most of Canada, where we have a really limited number of cases, the incidence is low and our testing capacity is getting pretty good, basically, and we're managing, whereas metropolitan Toronto and metropolitan Montreal are a different story; there still seem to be large numbers of cases, and they don't really seem to have it under control. I want to ask why there is a difference. Why are Montreal and Toronto not getting this under control?
The second part of the question will hopefully allow both of you to get a response in there. As long as it continues to circulate in Montreal and Toronto as we start to open up, if we allow people to travel from Montreal and Toronto, there's going to be a threat throughout Canada, including, as I think you know, Dr. Liu, in northern indigenous communities. Should it get into those communities, given their socioeconomic problems, their lack of health care is going to be a real problem.
What can Montreal and Toronto do to do better at getting it under control? Should there be some mandatory use of masks, particularly in mass transit? What can we in the rest of Canada do to help Montreal and Toronto get this under control?
Maybe I can start with Dr. Liu and then Ms. Krystal. Thanks.
