Systemic racism, restrictive policies block Black Canadians from blood donation

A person walks into a blood donation clinic in Canada wanting to help. They have a medical history—a malaria infection years ago, now resolved. They are turned away. Across the country, this scene repeats. Black Canadians who want to donate blood encounter a system of rules and practices that exclude them, even as hospitals desperately need their blood to treat patients with sickle cell disease, a condition that predominantly affects people of African descent.

The contradiction is stark and deliberate. Sickle cell disease requires transfusions of red blood cells matched to specific blood types and genetic markers. Patients do best when their donors share similar ancestry. Yet Canada's blood donation policies—managed by Canadian Blood Services in most provinces and by Héma-Québec in Quebec—systematically prevent Black people from donating. A malaria infection, even one treated and resolved years earlier, becomes permanent grounds for exclusion in Canada. The United States removed this restriction. France did too. Other G7 nations have reformed their policies. Canada has not.

Researchers at the University of Ottawa's Interdisciplinary Centre for Black Health wanted to understand why Black Canadians were staying away from donation clinics. They interviewed 42 Black adults, most of them university-educated, and found the barriers ran deeper than a single policy. Dr. Jude Mary Cénat and colleagues documented how the system itself—its rules, its institutions, its history—had constructed a wall.

The restrictive policies were one part. But they were inseparable from something larger: the lived experience of racism within Canadian healthcare. Study participants described negative encounters with doctors and hospitals. They spoke of feeling disrespected, of doubting whether they would be treated fairly. These were not abstract concerns. They were rooted in real history—the medical exploitation of Black people, the dismissal of Black patients' pain, the documented disparities in how Black Canadians are treated in emergency rooms and clinics. When someone from a community with that history is asked to give blood to an institution that has harmed them, the ask carries weight.

Historical anti-Black racism had done its work. It had created a distance between Black Canadians and the blood donation system, a sense that the system did not value them, that their contribution would not be welcomed or honored. Some feared rejection. Some feared harm. The distrust was not paranoia. It was a rational response to how they had been treated.

The researchers were clear about what needed to happen. The blood services organizations could not simply launch a recruitment campaign and expect Black Canadians to show up. They had to remove the policies that excluded people without medical justification. They had to acknowledge the racism—historical and ongoing—that had created the mistrust. They had to design engagement that respected Black Canadians' experience and their right to skepticism about institutions that had failed them.

Without these changes, the shortage would persist. Black patients with sickle cell disease would continue to receive transfusions from donors whose blood was not optimally matched. They would face worse outcomes. The system would continue to harm the very people it was supposed to serve, all while claiming it had no choice.
