Decades of research has found that racialized citizens are diagnosed with the disorder at far higher rates – and the single biggest risk factor is having darker skin than most of their neighbours


But the finding that Black citizens are being diagnosed more often with psychosis is more complex than improving access to care. It goes back more than 50 years and has been the subject of more than 100 peer-reviewed papers. In the United Kingdom and the Netherlands, extensive studies have found rates as much as five times higher in migrants from the Caribbean and Africa than the native-born white population. In Israel, significantly higher rates of psychosis have been found in migrants from Ethiopia. In the United States, African-Americans are more likely to be diagnosed with schizophrenia than white Americans.
Researchers have discovered a similar pattern in Canada. A 2015 Ontario study looking at 10 years of health statistics found higher rates of psychotic disorders in refugees from East Africa and South Asia (95 per cent and 51 per cent higher, respectively) compared to the general population, and an elevated risk among immigrants from the Caribbean and Bermuda.
