Hema-Quebec needs your help.
The blood bank has seen a drop in donations in recent weeks and because of that its supply of O- and O+ is running very low.
"All blood donations count, but we are launching a specific appeal to donors of these blood types" Hema-Quebec wrote on its Facebook page. "We need 200 more donations each day, in addition to the 1000 donations that are normally needed."
If you're interested in donating, which you can do every 56 days, you can find more information here.
