Canadian Blood Services is calling on people to roll up their sleeves in a final summer push for donations ahead of the long weekend.
"In B.C., we need probably about 220-250 people to come in and book an appointment. If we can get at least that many people, I think it would go a long way to meeting our needs for that particular weekend."
The organization's Ed Yee says a car accident victim may need the equivalent of 50 donations.
You can book an appointment either by phone or online.
