Our mission is collaboration.

The Ontario HIV Treatment Network is a non-profit funded by HIV and Hepatitis C Programs at the Ontario Ministry of Health. We're a node of collaboration; our work brings together key partners from across the sector to improve the lives of all Ontarians living with and at risk of HIV.

News and updates

Our goal is to improve the health and lives of people living with and at risk of HIV by using data and evidence to drive change. To do this, we work with testing programs and clinics, AIDS service and other community-based organizations to support needle-moving projects with real impact.

The OHTN works to build capacity across Ontario's HIV treatment, prevention and care cascade by providing quality data on the epidemic, reliable research on best practies, and education, training and other supports. Our projects engage Ontario ASOs, clinicians, researchers, and people living with HIV/AIDS in mutually supportive relationships.

Funding Opportunities

Through our HIV Endgame Program, we will offer a selection of awards to draw on Ontario's innovation expertise in ways that help us reach the Endgame. Our Endgame Strategic Plan lays out our plan to work with people living with HIV, affected communities, care providers, researchers and policymakers to make new HIV infections rare and to help people with HIV lead long healthy lives free of discrimination. We call this plan the HIV Endgame because we believe that by making the correct tactical moves over the next 10 years, we can stop HIV. Read the OHTN Endgame Plan to 2026.
