The Toronto Overdose Information System is a surveillance and monitoring system that allows for systematic and timely monitoring of trends in overdose-related outcomes in Toronto, with a current focus on opioids. Through this system, we aim to share information externally with partners and the public to increase community awareness of these trends. Additional data and indicators may be added as they become available.
