The policy began in 1992 as an outright ban on gay men donating blood following a tainted blood scandal. The agency says asking about sexual behaviour rather than sexual orientation will allow it to more reliably assess the risk of infections such as HIV.Ĭatherine Lewis, a spokeswoman for Canadian Blood Services, said the criteria change is “science-informed“ and allows the agency to be more inclusive about who can donate while still ensuring a safe blood supply. If they have, they will need to wait three months after such activity before donating blood.

Those who say yes will be asked if they have engaged in higher-risk sex. 30, potential donors will be asked if they have had new or multiple sexual partners in the last previous months, no matter their gender or sexual orientation.
