The Epidemiology of HIV in Canada

This fact sheet provides a snapshot of the HIV epidemic in Canada. All epidemiological information is approximate, based on the best available data. Most of the data contained in this fact sheet come from the latest estimates from the Public Health Agency of Canada, which are for the year 2020. More information can be found in the section “Where do these numbers come from?” at the end of the fact sheet.

What is HIV?

HIV stands for human immunodeficiency virus. HIV is a virus that can weaken the immune system, the body’s built-in defence against disease and illness. With proper treatment and care, people with HIV can live long and healthy lives and avoid passing HIV to others. There is no vaccine to prevent HIV but there are ways to avoid passing or getting HIV.

Why are certain populations disproportionately impacted by HIV in Canada?

HIV can affect anyone, no matter their age, sex, gender, sexual orientation, race or ethnic origin. However, certain populations carry a disproportionate burden of HIV in Canada. In Canada, the HIV epidemic is concentrated in marginalized communities, notably sexual minorities and racialized communities, because of structural and social factors that create health inequities.

While these populations have higher rates of HIV and carry a disproportionate burden of HIV compared with the broader population, this does not mean that being a member of one of these populations is itself a risk factor for HIV. Rather, the intersections of many factors and experiences over an individual’s lifetime can lead to increased risk among people within these populations. It is also important to recognize the strengths and protective factors that exist within each of these communities and to work to build on those strengths to support and enhance health and wellness.

What statistics are available in Canada to inform programming?

There are two main types of numbers available, HIV estimates and HIV surveillance data (reported HIV diagnoses).

HIV estimates are developed by the Public Health Agency of Canada through statistical modelling, using a variety of data sources. There are two main types of estimates:

  • Prevalence estimates tell us how many people are living with HIV at a given point in time. They include estimates for the number of people who are undiagnosed and take into account the number of people with HIV who have died.
  • Incidence estimates tell us how many people got HIV in a given year, including those who had not yet been diagnosed.

HIV surveillance data are published by the Public Health Agency of Canada and tell us how many people were diagnosed with HIV in a given year. This information does not tell us when they got HIV, just when the diagnosis was made. People may have had HIV for many years before diagnosis.

How many people are living with HIV in Canada (prevalence)?

According to national HIV estimates, there were 62,790 Canadians living with HIV at the end of 2020. This means that for every 100,000 Canadians, 170 people were living with HIV (prevalence rate).

How many people are living with HIV but don’t know it (undiagnosed) in Canada?

According to national HIV estimates, 6,590 people were living with HIV but didn’t know it (undiagnosed) at the end of 2020. This represents 10% of the estimated number of people with HIV.

How many new HIV infections are there in Canada (incidence)?

According to national HIV estimates, there were 1,520 new HIV infections in Canada in 2020. This means that for every 100,000 Canadians, four people became HIV positive in 2020 (incidence rate).

There was a small decrease in the number of estimated new HIV infections in 2020 compared with 2018, when there were 1,760 new HIV infections. This decrease may be due to the negative impact of the COVID-19 pandemic on access to HIV testing.

Among the 1,520 new HIV infections in Canada in 2020, 43.8% were among gay, bisexual and other men who have sex with men (gbMSM), 2.8% were among gbMSM who also injected drugs, 19.8% were among people who injected drugs and 33.6% were among heterosexual people.

How many new HIV infections are there in the provinces and territories?

According to national estimates, the provinces with the highest number of new HIV infections were Ontario, Saskatchewan and Quebec in 2020. There was significant provincial variation in the populations impacted by new HIV infections:

  • There were an estimated 108 new HIV infections in British Columbia in 2020: 51.8% were among gbMSM, 1.9% were among gbMSM who also injected drugs, 21.3% were among people who injected drugs and 25.0% were among heterosexual people.
  • There were an estimated 149 new HIV infections in Alberta in 2020: 32.9% were among gbMSM, 2.7% were among gbMSM who also injected drugs, 20.1% were among people who injected drugs and 44.3% were among heterosexual people.
  • There were an estimated 214 new HIV infections in Saskatchewan in 2020: 6.5% were among gbMSM, 2.9% were among gbMSM who also injected drugs, 62.6% were among people who injected drugs and 28.0% were among heterosexual people.
  • There were an estimated 85 new HIV infections in Manitoba in 2020: 9.4% were among gbMSM, 2.4% were among gbMSM who also injected drugs, 60.0% were among people who injected drugs and 28.2% were among heterosexual people.
  • There were an estimated 507 new HIV infections in Ontario in 2020: 58.6% were among gbMSM, 3.7% were among gbMSM who also injected drugs, 8.3% were among people who injected drugs and 29.4% were among heterosexual people.
  • There were an estimated 410 new HIV infections in Quebec in 2020: 52.4% were among gbMSM, 2.2% were among gbMSM who also injected drugs, 3.4% were among people who injected drugs and 42.0% were among heterosexual people.
  • There were an estimated 45 new HIV infections in the Atlantic provinces in 2020: 57.8% were among gbMSM, 2.2% were among gbMSM who also injected drugs, 13.3% were among people who injected drugs and 26.7% were among heterosexual people.  
  • There were an estimated 2 new HIV infections in the Territories in 2020. No breakdown by mode of transmission is available.

Is Canada reaching the global HIV targets?

The Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization (WHO) have established a global health sector strategy on HIV to help eliminate AIDS as a public health threat by 2030. Canada has endorsed this strategy. The strategy consists of the following targets for the years 2020 and 2025:

  • 90% of people with HIV have been diagnosed with HIV (2020)
  • 90% of people diagnosed with HIV are on HIV treatment (2020)
  • 90% of people on HIV treatment have achieved viral suppression (2020)
  • 95% of people with HIV have been diagnosed with HIV (2025)
  • 95% of people diagnosed with HIV are on HIV treatment (2025)
  • 95% of people on HIV treatment have achieved viral suppression (2025)

Of the estimated 62,790 people with HIV in Canada in 2020, an estimated:

  • 90% of people with HIV had been diagnosed with HIV (56,200 people)
  • 87% of people diagnosed with HIV were on HIV treatment (48,660 people)
  • 95% of people on treatment had achieved viral suppression (46,100 people)

While these numbers represent progress from 2018 (when an estimated 89% of people with HIV had been diagnosed, 85% of people diagnosed were on HIV treatment and 94% of people on treatment had achieved viral suppression) there is still significant work to be done. Overall, an estimated 16,690 Canadians living with HIV in Canada (26.6%) do not have a supressed viral load, including 6,590 people who are undiagnosed, 7,540 people who have been diagnosed but are not on treatment and 2,560 people who are on treatment but not virally suppressed. We need to better reach the undiagnosed through testing, ensure better engagement and retention in care for those who test positive and support people on treatment to attain a suppressed viral load.  

Are the provinces reaching the global HIV targets?

The number of new HIV infections in PWID is higher than the estimated 335 new infections in 2018.

People who use drugs are over-represented in new HIV infections in Canada. There were an estimated 239 new infections per 100,000 among people who had injected drugs in the past six to 12 months in Canada in 2020. This is significantly higher than the estimated four new infections for every 100,000 Canadians in 2020.

How is Canada doing at reaching the global HIV targets for PWID?

Two were born to people who did not receive any HIV treatment, three were born to people who received only some treatment and one infant was born to a person whose treatment status was unknown.

Key definitions

HIV prevalence—The number of people with HIV at a point in time. Prevalence tells us how many people have HIV.

HIV incidence—The number of new HIV infections in a defined period of time (usually one year). Incidence tells us how many people are getting HIV.

HIV diagnoses—The number of new HIV diagnoses in a defined period of time (usually one year). HIV diagnoses tell us how many people have been diagnosed within a certain time frame.

Where do these numbers come from?

Most of the data contained in this fact sheet come from Estimates of HIV incidence, prevalence and Canada’s progress on meeting the 90-90-90 HIV targets, 2020, the HIV in Canada, Surveillance Report to December 31, 2020, and HIV in Canada: 2022 Surveillance Highlights.

Estimates of HIV incidence, prevalence and Canada’s progress on meeting the 90-90-90 HIV targets, 2020

National HIV estimates are produced by the Public Health Agency of Canada using statistical modelling that takes into account some of the limitations of surveillance data (the number of HIV diagnoses reported to the Public Health Agency of Canada) and also accounts for the number of people with HIV who do not yet know they have it and the number of people with HIV who have died.

This report also compiles information from various sources to provide 90-90-90 estimates for specific populations.

HIV in Canada, Surveillance Report to December 31, 2020

Healthcare providers are required to report HIV diagnoses to their local public health authorities, including diagnoses resulting from anonymous tests. Each province and territory then compiles this information and provides it to the Public Health Agency of Canada. This information does not contain names or personal identifiers. Sometimes additional information is also collected and sent to the Public Health Agency of Canada, such as information about a person’s age, gender, ethnicity, exposure category (the way the person may have acquired HIV) and laboratory data such as the date of the HIV test.

This report also compiles data from the Canadian Perinatal HIV Surveillance Program maintained by the Canadian Pediatric and Perinatal HIV and AIDS Research Group. It also compiles numbers on immigration medical screening maintained by Immigration, Refugees and Citizenship Canada (IRCC).

HIV in Canada: 2022 Surveillance Highlights

Healthcare providers are required to report HIV diagnoses to their local public health authorities, including diagnoses resulting from anonymous tests. Each province and territory then compiles this information and provides it to the Public Health Agency of Canada. This information does not contain names or personal identifiers. Sometimes additional information is also collected and sent to the Public Health Agency of Canada, such as information about a person’s age, gender, ethnicity, exposure category (the way the person may have acquired HIV) and laboratory data such as the date of the HIV test.
