Canadians "from far and wide" have the power to save or improve up to three lives this Canada Day weekend. All it takes is about an hour of your time and a bit of national spirit. Blood and platelet donations normally decrease around long weekends and summer holidays because people are away or busy with family activities. Meanwhile, the demand for blood usually increases due in part to more trauma cases.

While blood donors of every type are needed every day, right now we are looking for some additional O-Negative donors. We are running a little low on type O-Negative, and would like to top up our inventory.

Only 7% of Canadians have type O-Negative blood. If you are part of this select group, your donations make a real impact in helping others. O-Negative is the lone blood type that is compatible with all others. During an emergency, when there is no time to check a patient's blood type, O-Negative can be given to all patients.

If you are eligible to donate blood, please help us raise O Neg levels and all blood types by calling 1 888 2 DONATE and book your appointment today. Donating blood is a great way to demonstrate "true patriot love".
