By health region

Data source: Ontario HIV Laboratory Cohort
 

Key points

  • Health regions are aggregations of public health units and their boundaries. See Technical Notes for more information.
  • Health region data is only available from 2011 onwards, as address of residence was not collected prior to that year. For this reason, the figures below only present data for the year 2015. Data from 2011 to 2015 are available in the tables at the end of the page.
  • The majority of people with diagnosed HIV living in Ontario in 2015 were in Toronto (54.3% or 8,649 people), followed by the Central East (12.1%), Central West (10.5%), Ottawa (10.2%), South West (6.8%), Eastern (3.3%) and Northern (2.8%) regions.
  • In 2015, the number of people with diagnosed HIV per 100,000 of the population was 305.9 in Toronto, followed by 170.3 in Ottawa. This number ranged from 46.7 (Central East) to 66.7 (South West) in the remaining health regions.

Notes: Data provided by Public Health Ontario Laboratories. Diagnoses assigned to a health region based on their address of residence or, if unknown, the address of the ordering provider. Individuals living out of province (approximately 1% each year) or with missing health region (approximately 0.1% each year) were excluded. Tables and Figures display main estimates only. A range of plausible values are available upon request.
