On the night of Sunday June 14, a fire erupted in a mixed‑use industrial and commercial building on Avenue du Pacifique in Lachine, a borough of Montreal. Approximately 70 firefighters were deployed to the scene, and the blaze continued for roughly four hours into the early hours of Monday, June 15.
The structure, described as a mixed‑use building, housed both industrial and commercial activities. Fire crews arrived shortly after the alarm was raised and began containment efforts. The large number of personnel reflected the scale of the incident and the need to protect adjacent properties. The building's mixed‑use nature meant that both industrial equipment and commercial goods were present, increasing the complexity of the firefighting effort.
Firefighters worked through the night, employing hoses, ladders and other equipment to bring the fire under control. By the early morning hours, the flames were extinguished and the scene was secured. No additional details about injuries or property loss were released at the time of reporting.
Lachine has previously dealt with industrial fires, and the response to this incident underscores the capacity of municipal emergency services to mobilize significant resources quickly. The four‑hour operation demonstrated coordination among multiple fire units and the ability to sustain a prolonged effort.
Authorities will continue to investigate the cause of the fire. The building remains closed pending further assessment, and residents in the surrounding area were advised to stay clear of the site while cleanup and safety checks proceed. The fire department will also conduct a post‑incident review to evaluate response tactics and identify any lessons learned. Officials said the site will remain inaccessible until engineers confirm that the structure is safe for entry.
