Join us in conversation with Dr. Joe Vipond, Emergency Physician, a founder of Masks for Canada and President of the Canadian Association of Physicians for the Environment. His commitment to saving lives has taken him to the frontlines of the coal campaign, made him an early and outspoken proponent of mask wearing in Canada, and along the way forged unlikely friendships including with our Greta Thunberg.
