The change will go into effect by the end of September.Ĭanadian Blood Services, which operates in all provinces except Quebec, had requested the change to Health Canada criteria following several other revisions of the ban in recent years. Health Canada will no longer ask men if they have had sex with another man within three months of donating blood, and will instead screen donors of all genders and sexual orientations for high-risk sexual behavior equally, according to a release. Canadian health authorities on Thursday announced that this fall they will lift a ban on blood donations from men who have sex with other men, making eligibility criteria the same for them as for every other donor.
