Several residents in a downtown Hamilton apartment complex were evacuated amid a hazardous materials call on Tuesday afternoon.
Hamilton fire say bear spray was released on one of six floors at a Cathcart Street residence near Wilson Street and Wellington North.
About 50 residents were ushered out of the building and into buses by fire crews as a precaution.
Paramedics didn’t have an exact number of how many people they assisted with minor complaints.
Five ambulances were on the scene during the evacuation but did not transport any patients to hospital.
Firefighters were able to contain and disperse the airborne material eventually allowing residents to return to their units late afternoon.
