Canada HIV & AIDS Statistics

HIV statistics

At the end of 2011 there were an estimated 71,300 people in Canada living with HIV - up from 57,000 in 2005.1 Of these, around 25% were unaware of their infection. It is estimated that about 3,175 new HIV infections occured in Canada in 2011, which is roughly the same as the figure for 2008.

From the start of testing in November 1985 until the end of December 2011, there have been 74,174 positive HIV tests reported to PHAC (Public Health Agency of Canada). In 2011, there were 2,221 positive test results reported to PHAC (meaning 954 cases of the 3,175 new HIV infections were not reported to PHAC). This figure includes some persons not featured in the table below since they were under 15 years old; their gender was not reported; or they were reported as transgender.2

In the period 1985-2001, the men having sex with men category accounted for 62% of adult HIV diagnoses for which exposure category was reported. The equivalent proportion was 48.6% in 2011.4 Men who have sex with men (MSM) remains the largest single exposure category.
