My next question is for Dr. Tam.
Dr. Tam, as I said at the onset, I think you can understand the concern of Canadians about having this information collected, I would argue, without their consent. I'm wondering why this information would be so important when public health agencies across Canada federally, provincially, municipally, territorially have access to data that could inform public health response, and not just now but going forward. If all of this information is there, why would we put at risk the privacy of Canadians by tracking their mobility data when all of this information already exists? There are significant risks and we'll hear about these as we get the security and privacy experts in front of us, but why would you not just use the data that's available to you and other government data that's available to determine public health response, both for COVID and in the future as it relates to the RFP?
