2026 marks the 10th anniversary of the Undetectable = Untransmittable (U=U) campaign, an important milestone in the global HIV response. Over the past decade, this evidence-based message has helped reduce HIV-related stigma and discrimination, empowered people living with HIV, and reinforced the vital importance of access to testing, treatment, and ongoing care.
As a champion of U=U, the Public Health Agency of Canada has supported efforts to advance U=U across Canada. Explore the timeline below to learn more about PHAC's contributions over the past decade.
