Project funding for the development of sustainable, effective HIV programs and services. This funding stream will support implementation science initiatives that will contribute to a rapid learning system for HIV. 

OHTN will support data, evidence sharing, and impact initiative that will drive change in one or more of the following areas of learning: 

Rapid Learning Areas 

  1. Effective PrEP scale-up in Ontario 
  2. Population-focused prevention and health promotion 
  3. HIV testing 
  4. Linkage, adherence, and retention in care 
  5. Clinical care standards and capacity 
  6. Integration of services 
  7. Mental health and well-being of people living with and at risk of HIV (including stigma reduction) 

Populations Most Affected by HIV 

  1. People living with HIV 
  2. Men who have sex with men 
  3. People who use drugs 
  4. African, Caribbean and Black communities 
  5. Indigenous communities 
  6. Women* 

Women* = Cis and Trans women, including African, Caribbean and black women, women who use drugs, Indigenous women, and other women who face systemic and social inequities, are more likely to be exposed to HIV through a sexual or drug using partner.


Teams must have a documented history of working with people living with HIV, clinicians, community-based organizations, policy makers, and researchers in a collaborative and culturally respectful manner.

The Nominated Principal Applicant must:

  • Hold a primary appointment at an appropriate host organization in Ontario. Eligible institutions include university faculties and departments, research institutes and hospitals, and HIV agencies.
  • Have primary employment and residence in Ontario.
