About the Campaign: The number of blood donors in Canada has been in decline, especially among young adults. At Canadian Blood Services, we’re redefining what it means to “make your mark” by positioning blood donation as the ultimate pre-tattoo ritual for Gen Z. With over 40% of them already sporting ink, they’re on track to become the most tattooed generation yet. Tattoos are permanent, and so is the impact you can make. Canadian Blood Services wants Gen Z to leave a mark that is more than skin deep.
