HIV statistics
At the end of 2005 there were an estimated 58,000 people in Canada living with HIV - up from 50,000 in 2002. Of these, around 30% were unaware of their infection. It is estimated that between 2,300 and 4,500 new HIV infections occur in Canada each year, though many of these are not reported right away.
From the start of testing in November 1985 until the end of December 2007, there have been 64,800 positive HIV tests reported to CIDPC (Centre for Infectious Disease Prevention and Control). In 2007, there were 2,432 positive test results. 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.
