About Men Who Have Sex with Men

Why we talk about this screening criterion

Before the introduction of testing for human immunodeficiency virus (HIV) in the mid-1980s, thousands of Canadians were infected through tainted blood products. Being solely responsible for Canada’s blood supply at that time, the Canadian Red Cross Society introduced a donor eligibility criterion that excluded all men who have had sex with a man even once since 1977. This criterion was embedded into Health Canada regulations in 1992.
