Twenty years ago, a little before I began my career, I learned in dribs and drabs that there had been a memorable squabble between officials at the Pest Management Regulatory Agency and Health Canada officials in the therapeutic products directorate at the time.
Unfortunately, the officials in the therapeutic products directorate lost the fight, and are now faced with a thorny problem. According to the Canadian definition, a disinfectant is a “drug”, because the product is designed to prevent a disease on a surface. In Canada, as I said earlier, a table is “treated”. That is what the officials told you on Tuesday. Surfaces are treated to prevent disease from being transmitted to humans. That forms the basis of Canadian regulations, and that's why linking them to U.S. or G7 regulations doesn't work.
