Emergency responders donate blood to kickoff Sirens for LifeBy Lethbridge Herald on August 5, 2026. Canadian Blood Services community development manager, Lisa Castro said that as summer continues, donation routines have slowed while the need for blood remains constant. She said that because of that donors of all blood types are needed now to help ensure hospitals have the blood products patients rely on every day. She said they need donors that maybe have not donated for a while to book an appointment and stop by to donate. To book an appointment to donate blood, visit blood.ca, use the GiveBlood app, or call 1-888-2-DONATE (1-888-236-6283).
