Canada’s blood supply has fallen sharply this summer, dropping nearly 20 per cent since June 1.
Canadian Blood Services says several blood types have only limited days on hand, which the agency says is not sustainable if the trend continues.
The organization says it needs about 18,000 booked appointments each week to meet hospital demand.
Over the past six weeks, appointments have fallen short by 1,500 to 2,500 weekly, which has required a draw on existing inventory.
While a seasonal dip in donations is expected during the summer, Canadian Blood Services says current numbers are well below typical patterns.
“We’ve seen the blood supply decline by about 20 per cent in just a matter of weeks, and we need more donors to come forward now to reverse this decline,” said Ron Vezina, vice‑president of donor engagement and corporate reputation.
He said blood lasts only 42 days, meaning donations move quickly to patients, and added that hospitals rely on a steady supply for everyday care and emergencies.
To increase opportunities to donate, Canadian Blood Services has added weekend appointments at many donor centres and opened whole blood appointments at several plasma centres.
Vezina said both new and returning donors are welcome and suggested bringing a friend to donate together.
The agency says keeping existing appointments is important, and cancelling ahead of time allows someone else to take the spot.
Eligible donors can book online, the GiveBlood app or by calling 1‑888‑236-6283.
