The Waterloo Regional Police Service is investigating an incident where a harmful spray was used during a house party in Waterloo, Ontario, on March 14, 2026. Officers were called to a residence near Albert Street and Central Street at approximately 11:25 p.m. following reports of a disturbance.
Police say that unknown suspects used a noxious substance on several party guests before running away from the area. Paramedics with Emergency Medical Services arrived shortly after to treat those who suffered minor injuries, and all individuals were cared for at the scene.
This incident took place during a weekend with an increased police presence across the city due to St. Patrick’s Day celebrations. While there were large public crowds nearby, investigators believe this was a specific disturbance at a private home and not part of the larger gatherings.
The General Investigations Unit is currently leading the case and is looking for any information that could help identify the suspects. Police are asking anyone who may have seen something unusual near Albert and Central Streets on Saturday night to contact them with tips.
