I think the key term there is “peer-reviewed”. The agencies themselves are looking at peer-reviewed science. You're absolutely right that in the daily bombard of social media, we're hit with a number of studies of varying quality. The good news is that we have regulatory agencies who have a statutory responsibility to review peer-reviewed studies. I think when we allow them to do that, generally the results are very good. Canada is a world leader in science-based regulation. We do well on that.
