Thank you very much for that question.
Health Canada does not play a role in the occupational health and safety space, but I can offer that there is a very elaborate occupational health and safety program across the country, delivered from both provinces and territories and at the federal government, through the labour program in Canada.
Department of National Defence officials could speak more eloquently about how they communicate to workers the risks that may be at their facilities, whether they are from just regular practices, day-to-day activities or exposure to contaminated sites. Again, there is a well-defined list of chemicals currently in commerce. There's a well-identified body of science, which is evolving, that understands the risks. The current occupational health and safety program is reliant on a base of decades of science that understands these chemicals and other risks that may be present in the workplace.
