Peaceful Resolution of a Person in Crisis

Posted On Saturday October 01, 2022

Region of Peel – After a seventeen hour negotiation, investigators have charged an individual in relation to a critical incident in Mississauga.  

On Friday, September 30, 2022, at 7:40 a.m., police responded to a professional building in the area of Eglinton Avenue West and Erin Mills Parkway in the City of Mississauga.

When police arrived, they were alerted to an individual in possession of several firearms, who had barricaded himself  in a medical office building.  This individual presented a signficant risk to public safety, as well as the safety of all responding officers, as this building is in immediate proximity to a major health care facility that provides critical care to the residents of Mississauga and beyond.

A Crisis Negotiation Team (CNT) attended and facilitated the safe evacuation of all occupants of the building.  Members of the CNT maintained continuous contact with the individual in order to facilitate a peaceful surrender.

Shortly after 12:00 a.m., on October 1st, the incident was resolved, and the individual was taken into custody.

William Horodyski, a 66-year-old man from Calgary, has been charged with the following significant Criminal Code offences:

•           False Alarm of Fire

•           Mischief

•           Careless Use of Firearm

•           Possession of a Weapon for a Dangerous Purpose

•           Forcible Confinement x3

•           Mischief Lawful Enjoyment

Investigators from the 11 Division Criminal Investigation Bureau will be working closely with the Calgary Police Service over the next number of weeks in an attempt to understand fully the nature of the incident, and the motives of the individual charged.  This was an isolated incident, which has been resolved and there is no longer risk to public safety.
