OHRN's role is in transition:

CATIE is expanding its role in Ontario to provide tailored harm reduction knowledge exchange and capacity-building activities. This work, funded by the Ontario Ministry of Health, will include the delivery of webinars, online learning, dialogues and more to advance the skills and knowledge of ministry-funded frontline and community providers.


This role will include coordinating and supporting a network of harm reduction outreach workers across Ontario, as well as broader supports for other community-based, clinical and public health workers. It will begin April 1, 2023, and build upon a strong foundation of work previously led by the Ontario Harm Reduction Network (OHRN).
