UPDATE: Downtown Hamilton Hazmat Investigation

Hamilton fire responded to Mary St. for a hazmat investigation


Hamilton Police, Fire and EMS were dispatched to 238 Mary Street near Robert off of Canon for multiple reports of odours.

Upon arrival to the scene, Hamilton fire department started an investigation into the scent of odours and have determined that it did not come from a home or the business they originally responded to. Instead they say that a petroleum liquid was found in the local sewer system. Hamilton fire did say that they were unable to confirm exactly what the chemical in the sewers was at this time. It has since been confirmed to be the scent of gasoline.

Upon this discovery, homes in the immediate area were evacuated and Hamilton Street Railway (HSR) provided three city buses to provide a temporary shelter. Hamilton fire also put in a request for Hamilton Police to come and assist them with blocking off the roads and requested that an ambulance comes and stage in the area. All actions taken during this event were precautionary, but for a short time the following streets were closed:

  • Mary St. from Canon St. East to Barton St. East
  • Elgin St. – From Canon St to Robert St.
  • Catharine St. – From Mary St. to Elgin St.

Hamilton fire told us that as well as the street closures approximately 60 homes were evacuated as a precaution and have also confirmed that they did get some readings in residential properties. At this time, they have stressed that there’s no danger to the public. Within the time-frame from 12:30 – 13:00 they were able to release some of the units from the scene and downsize. The city of Hamilton has called in a third-party company to come and assist them with testing and flushing out the sewers in that area. Residents are expected to be able to return home very shortly.
