The family of a man fatally shot by Waterloo Regional Police plans to file a lawsuit against the police service.

Beau Baker was killed last April, outside a townhouse on Brybeck Crescent in Kitchener.

An investigation by Ontario’s Special Investigations Unit found that Baker had threatened to kill himself and to harm others, and called 911 to say that he had a knife and police would have to take it from him by force.

A responding officer found Baker standing outside the townhouse, clutching a knife.

After a brief standoff, the SIU found, Baker started to approach the officer – who then fired his weapon several times, killing Baker.

Afterwards, the officer and a colleague attempted to perform CPR on Baker.

The officer was not charged in connection with the shooting. The SIU determined that his actions were necessary to defend community safety.

Toronto-based criminal lawyer Davin Charney says he’s representing Baker’s family, and plans to file a lawsuit against Waterloo Regional Police on their behalf on April 4.

A rally will be held in front of the Kitchener courthouse on the same day, Charney said.
