I thank you, Chair, and I thank the witness for the response.
In addition to slowing down people's arrivals, we've also seen the emergence of evidence that this type of arrival testing is not effective. I'm seeing that there are few countries that are actually continuing to employ arrival testing. I'll ask two question because I only have a minute and a half left.
Why is PHAC continuing to pursue this particular method? Controls are important, but why are we continuing with this one at Canada's biggest airports? Second, wastewater testing is a better early warning tool than arrival testing, so I'm wondering if PHAC is undertaking steps to expand the use of wastewater surveillance.
