It's not just Canada. It's in the US as well. That same question is on all the US donor questionaires.
Also I just found out something else. I was a lifetime donor of platelets through apherisis. Basically once or twice a month you sit connected to a blood machine for two hours that separates out the plasma and platelets and returns the RBCs to you. I was in the five gallon+ contribution class. I had been donating for over fifteen years.
When I started HRT I told the donation center that I was a transsexual and I intended to eventually transition. I was immediately deffered, permanently. Polite words for banned. According to the FDA transsexualism constitutes a dangerous lifestyle (read queer, ->-bleeped-<-got, and all other hate related terms you can think of) and like (ugh) *homosexuals* are much more likely to spread AIDS and have other cooties, so they should not be allowed to taint the blood supply of right thinking, christian, people.
Now if they can figure a way to prevent such undesirables from consuming said precious blood products, life would be perfect for them.
I'm sorry, that was mean and cynical to say. But I am a transsexual and I was banned when I openly and honestly outed myself. My lifestyle didn't change. And probably won't. And despite whatever you put on those questionaires each and every pint of blood or blood product that is donated is tested for AIDS and HIV related diseases.
I'm still stinging a little bit from the blatant discrimination.
