National supplies remain at acceptable levels, but local officials say they've been struggling to find donors for months.
Stephanie Scott received several blood transfusions after emergency surgery on a large abdominal tumour earlier this year.
"I never thought I would ever need blood," said Scott.
"Within a few minutes of my third transfusion I was feeling a bit more human. I'll never forget it, it was amazing."
Ed Yee of the B.C. region of Canadian Blood Services is urging British Columbians to donate as soon as possible to help top up the inventory.
"About 50 per cent of all Canadians will know someone directly, either a family member or a friend, or may personally require a blood product at some point in their life," he said.
Scott believes people should remember they might need blood themselves one day.
"I know every day people wake up and they think it's going to just be a normal day. And that's what they have to remember, is that it might not be," she said.
"You might be in a car accident, you might need surgery, or you might get sick and these things happen. And that's why as a community we have to come together and help each other out."
