Data source: Ontario HIV Laboratory Cohort
- In 2015, the majority of people with diagnosed HIV living in Ontario were 45 years of age or older (62.6%).
- Cascade estimates were generally lower for younger individuals. In 2015, the percent of people with diagnosed HIV who were virally suppressed was 64.2%, 67.9%, 76.4%, 82.2%, 85.6% and 86.7% for those aged 24 or younger, 25 to 34, 35 to 44, 45 to 54, 55 to 64, and 65 or greater, respectively.
- Higher cascade indicator estimates among older individuals may be due to several factors. For example, many older individuals have been diagnosed for a longer period of time and have had more opportunity to progress through the cascade. However, individuals who were newly diagnosed at older ages were also more likely to achieve viral suppression within six months of diagnosis. This suggests that the higher estimates among older people are not solely due to being diagnosed for a longer period of time (as newly diagnosed analyses adjust for time since diagnosis).
- Data for the year 2015 only are shown below. Trends over time are available elsewhere on this website.

|Cascade indicator||Definition (main)|
|Diagnosed||Nominal HIV-positive diagnostic test or HIV viral load test, and not administratively lost to follow-up after 2 years|
|In care||At least one VL test in a given year|
|On antiretroviral treatment||Documented on ART, or ART status missing and suppressed, on last VL test in a given year|
|Virally suppressed||VL less than 200 copies/mL on last VL test in a given year|
Notes: Data provided by Public Health Ontario Laboratories. ART status documented on viral load test requisition by ordering provider and missing for 17-20% of requisitions. Individuals missing information on age were excluded (approximately 0.2%). Tables and Figures display main estimates only. A range of plausible values, based on alternate definitions, are available upon request. VL=viral load. ART=antiretroviral treatment.
