Canadian Blood Services has announced that more than 22,000 donors are urgently needed across Canada. All donors are urged to get involved, particularly donors with Type O blood. O-negative blood is always in demand by hospitals because it is the only type compatible with all other blood types. In an emergency, when seconds count and there is no time to check blood type, patients receive O-negative blood. Visit blood.ca, download the GiveBlood appointment or call 1-888-2-DONATE to find a nearby donation site. Walk in appointments are usually available.
