Pandemic causes blood shortage in Canada

A return to a somewhat normal summer as COVID-19 restrictions are eased is putting a strain on Canada's blood supply.

Several provinces have started lifting restrictions — most notably Alberta, British Columbia and Saskatchewan — and demand is increasing as a result.

Tracy Smith from Canadian Blood Services says people are resuming activities and hospitals are trying to catch up on backlogged surgeries.

She says the blood agency has extended hours at some donation centres and mobile clinics in anticipation of an increased need.

But many pandemic safety precautions remain in place, including a limit on the number of donors allowed inside at one time.

Demand for blood products tailed off dramatically 16 months ago as a result of less travel and the cancellation of all but the most critical surgeries.
