Overview

• 1,826 new HIV diagnoses in 2024 (excludes Quebec).
• National rate of new HIV diagnoses for 2024 – 5.7 per 100,000 population (excludes Quebec).
• The data included on this page is the best available data as of December 1, 2025. This page will be updated once more data becomes available.

Data notes

• No data was provided for 2024 for Quebec.
• For comparison purposes only, excluding Quebec data, for 2023 the national rate was 6.3 per 100,000 population, and there were 1,958 new HIV diagnoses.
• Data for 2024 excludes cases that have been previously diagnosed outside of Canada (e.g., prior to immigration) or in another province or territory, when known.
• Data presented do not account for age and sex rate variations between provinces and territories.
• Note that for Manitoba cases, information collected in 2024 about heterosexual sex as a route of exposure or transmission is not reportable in a compatible format. As such, these cases were assigned to other exposure categories; however, heterosexual sex is an important factor in HIV transmission in Manitoba.
• If discrepancies exist between data summarized and provincial or territorial reports, the most recent provincial or territorial report should be utilized.
• TR: territories, AT: Atlantic provinces.

Perinatal HIV surveillance

• 254 infants born to people living with HIV.
• 95.7% of pregnant people living with HIV received perinatal antiretroviral therapy (ART).
• 1 infant was born with HIV transmitted perinatally, and was born to a pregnant person living with HIV who did not receive any ART.
• Based on sentinel surveillance representing 95% of infants who were exposed to HIV.
