MSM eligibility:
three months

To be eligible to give blood, men who have sex with men (MSM) have to wait for a certain period of time after their last sexual intercourse with another man. In December 2018, Canadian Blood Services and Héma-Québec formally requested that Health Canada further reduce this period from one year to three months.

This proposed change was based on scientific evidence and supported by extensive stakeholder input. The submission was approved and the new eligibility standard became effective in June 2019. Meanwhile, Canadian Blood Services and Héma-Québec, with funding from Health Canada, are supporting 15 evidenced-based research projects investigating alternative screening approaches for blood and plasma donors — the findings from which could help to further evolve MSM eligibility criteria.
