In 2016, we were successful in advocating for new municipal policy in Toronto that would open cold weather drop-ins earlier in the season, and allow them to remain open continuously over the coldest winter months. Our 2019 and 2023 studies prompted the City of Toronto to increase temperature thresholds for activating warming centres from -15C to -5C. An evidence-based brief summarizing the research remains one of the most-visited pages on the MAP website.
