Canadian Blood Services is encouraging Prince Edward Islanders to make an appointment to roll up their sleeves this holiday season.

Spokesperson Michelle Thibodeau Coates said while blood donation is typically strong at this time of year, there is an appointment gap on P.E.I between Christmas and New Year's Eve.

“We actually have close to 100 appointments open on just two days and that's Christmas Eve, so December 24th, as well as December 27th. Those are two days right that are critical for us to go ahead and get some donors booked into those time slots and make sure that we're able to provide the product that's needed to hospitals,” she said.

Thibodeau Coates said there's also some concern with the stormy weather predicted for Sunday and mid-week.

She said that can mean missed appointments.

While Canadian Blood Services tries to keep clinics open, Thibodeau Coates said that's not always possible in a storm.
