Book an Appointment

For your safety and the safety of the patients, all volunteer blood donors must be evaluated to find out if they are eligible to give blood. Whether you are donating for the first time or checking to see if you can continue to donate, the following information will help you before you book an appointment or visit a clinic.

When you go to donate, you will be asked a number of questions to determine your eligibility. One of our qualified team members will make the decision about whether or not you are eligible to donate.

Am I eligible to donate?

To become a blood donor in Canada you must be:

  • In good general health, feeling well and able to perform your normal activities
  • At least 17 years old
  • Meet our height and weight requirements if you are between 17 and 23 years old. Use our calculator to determine if you are ready to donate.

What is your age?


 

On the day of your donation, it is important that you have eaten and had adequate sleep.

If you’re 61 or older and have not donated before, your eligibility must be assessed by a doctor. Bring the following letter (PDF) — filled out and signed by your doctor — when you come for your visit.

Remember: if you do not meet the requirements today, there are lots of other ways to get involved with Canadian Blood Services. Plus, you can always check in with us again to see if your eligibility has changed.

How often can I donate?

It depends on the type of donation you’re making:

  • Every 56 days for whole blood
  • Every seven days for plasma
  • Every 14 days for platelets

Can I continue donating as I get older?

If you’re between the ages of 67 and 71 and have not donated in the last two years, your eligibility must be assessed by a doctor. Have your doctor fill out and sign this letter (PDF), and bring it with you when you visit the clinic.

At 71, you require an annual assessment by a doctor and must have donated within the last two years to continue donating. You must provide a doctor’s letter every year.

Can I donate to Canadian Blood Services if I’m from Quebec?

Residents of Quebec can donate at any Canadian Blood Services clinic, although we do not operate clinics within the province. If you make a blood donation to Héma-Québec within Quebec, your donation will be acknowledged as part of your Canadian Blood Services donation count. Learn more about Héma-Québec.
