Source-derived summary

Edmond Wai-Hong Yu (余偉康; October 2, 1961 – February 20, 1997) was a Hong Kong Canadian former medical student whose death after being shot by a constable of the Toronto Police Service sparked debates about the police's use of force, mental illness, and the treatment of those diagnosed with a mental illness and struggle with homelessness.

Early life and mental illness

Yu was raised in Hong Kong and immigrated to Canada in 1982. While young, Edmond won the Hong Kong city boxing championship. He attended York University from 1982 to 1984, studying pre-medicine. In 1984 he was accepted as a medical student at the University of Toronto.

In 1985, police arrested Yu and took him to the Clark Institute of Psychiatry, where he was diagnosed with paranoid schizophrenia and later on became homeless.

Death

On February 20, 1997, Yu assaulted a woman at a bus stop, then boarded a bus. Police attempted to board the bus, at which point Yu, according to witnesses, raised a small hammer. Constable Lou Pasquino fired six shots, hitting Yu three times.

An official inquest in 1998–1999 cleared the police of wrongdoing and resulted in a number of recommendations.
