Can I donate to Canadian Blood Services if I’m from Quebec?
Residents of Quebec can donate at any Canadian Blood Services donor centre in Canada, though we do not operate centres within the province of Quebec. If you make a blood donation at a Héma-Québec donor centre, your donation will be acknowledged as part of your Canadian Blood Services donation count.
It only takes about an hour of your time to change someone’s life. If you are in good health and meet our eligibility criteria, you can donate blood as frequently as every 56 days for males and every 84 days for females.
If you are in good health and meet out eligibility criteria, you can donate plasma as frequently as every seven days. To become a plasma donor, having a history of making regular blood donations helps, but is not always necessary.
When a blood vessel is damaged, platelets cluster together and stick to the opening of the broken vessel to plug the hole. If you are in good health and meet our eligibility criteria, you can donate platelets as frequently as every 14 days.
