In the summer of 2023, Bruce Lanphear, Professor of Health Sciences at Simon Fraser University, resigned his position as co-chair of a recently formed Science Advisory Committee of the PMRA, which regulates pesticide use in Canada. Dr. Lanphear felt he could no longer lend his credibility to the agency following disagreement about the Terms of Reference provided to Lanphear and seven other scientists comprising the committee.
Lanphear has been critical of aspects of Canada's pesticide oversight regime. I invited him on the show to discuss the topic.
