Importance of ethnic diversity
For people with rare blood types or ongoing and complex treatment needs, an ethnically diverse blood supply can mean the difference between life and death.
You may already know that the best hope for someone in need of lifesaving transplant is a donor who shares their ethnic background or ancestry. But did you know that many patients also require specially matched blood? Because blood type is inherited, people with complex blood needs often rely on donors of similar ancestry.
To truly be Canada's Lifeline, we need our donor and registrant base to reflect Canadian society, especially in racial and ethnic diversity.
There is an urgent need for greater ethnic diversity within Canada’s Lifeline, as people from diverse ethnic backgrounds, including those with mixed ancestry, are far less likely to find a stem cell match than someone who identifies as white.
African, Caribbean and Black registrants make up just 2% of the stem cell registry
Members of Lambda Mu Mu - Canada's Chapter - Omega Psi Phi Fraternity Inc, International 13th District share donors from Black communities are currently underrepresented in Canada's stem cell registry and how building awareness can make all the difference. The more people who register to donate stem cells, the better chance someone with a life-threatening blood disorder or blood cancer will receive a transplant.
Rare blood types by ethnic, racial and Indigenous groups
Some people have rare blood types that fall outside of ABO groups. The table below shows certain blood types are described only in specific racial and ethnic groups. That's why it's essential for donor diversity to match the patient diversity.

Composition of our blood donor base and the stem cell registry
Currently, people in Canada who are from ethnically diverse backgrounds are less likely to find a matching donor than someone who is white. Only half of the hundreds of people across Canada who are waiting for a stem cell transplant typically find a match, for instance.
This is because donors from these ethnically diverse communities are currently underrepresented in our donor and registrant pools.
It’s critical for us to further grow and diversify our donor and registrant pools to ensure that people from all communities in Canada can find their lifesaving match.
