About CATIE

CATIE is Canada’s source for HIV and hepatitis C information, and so much more.

We increase knowledge about sexual health and substance use, we build the capacity of service providers to deliver prevention, testing and treatment services, and we promote policies and programs proven to work based on research, practice and lived experience.

With gratitude and respect, CATIE acknowledges that our work takes place on Indigenous land across the country.

How we do it

Increasing knowledge

  • A comprehensive website for HIV, hepatitis C, sexual health and harm reduction information
  • Regular bulletins on new research and implications for frontline programs
  • Interactive online courses and webinars

Building capacity

  • Fact sheets, research summaries and guides for frontline workers
  • Print publications for clients delivered free of charge through the CATIE Ordering Centre
  • Educational opportunities in partnership with local organizations

Strengthening programs

  • Case studies of effective HIV, hepatitis C, sexual health and harm reduction programs
  • Evidence reviews, guidelines and other tools for program developers
  • Gatherings and events to discuss innovative approaches

While anyone can be at risk for HIV, hepatitis C or harms related to drug use, these issues disproportionately affect Indigenous, Black, queer and trans people, people who use drugs, immigrants and newcomers, and other communities that have been or continue to be marginalized within mainstream structures of power.  This is not a coincidence, and is directly related to the stigma, discrimination and structural factors that create health disparities and prevent people from accessing health services and information. By working with and sharing knowledge from and for the communities most affected, we are working to undo the structural drivers of these public health concerns.

CATIE's history

For 35 years, CATIE has bridged the gap between what we know and what we do, with a particular emphasis on people and communities underserved by the healthcare system.

We started as a treatment information exchange for and by people living with HIV and their allies. And as health information needs evolved, so did we.

Our full legal name is the Canadian AIDS Treatment Information Exchange, but we operate under the name CATIE.
