A London Police Service constable was charged with dangerous driving contrary to section 249(1)(a) of the Criminal Code after responding to a Code 1 armed robbery call.
While responding with lights and sirens activated, the officer approached an intersection controlled by a red light.
The officer slowed significantly but did not come to a complete stop, failed to reactivate her siren (which she had turned off per a sergeant's direction), and did not see an oncoming vehicle proceeding on a green light.
The collision resulted in injuries to two pedestrians and occupants of the other vehicle.
The trial judge acquitted the officer, finding that while the conduct constituted the actus reus of dangerous driving, the Crown failed to establish the required mens rea of a marked departure from the standard of care expected of a reasonable person in the officer's circumstances.
