The Service de sécurité incendie de Montréal (SIM) responded to a blaze at an industrial building on Avenue du Pacifique in the Lachine borough on Thursday, June 18, 2026. This incident marks the second fire at the same site in a span of three days.

Firefighters arrived shortly after the alarm was raised and began suppression efforts to contain the flames. The building, located in a mixed‑use industrial area, was the focus of intensive operations as crews worked to prevent the fire from spreading to neighboring structures. The response was coordinated by SIM personnel who deployed the necessary equipment to address the emergency.

The earlier fire at the same location occurred two days prior, prompting heightened awareness of the site. Authorities noted that the recent incident underscores the importance of ongoing monitoring and safety checks following the first blaze. While details of the cause remain under investigation, SIM officials confirmed that the fire was fully extinguished and that no injuries were reported among workers or nearby residents.

Following the incident, the fire department conducted a thorough assessment of the damage and secured the perimeter to ensure public safety. The building sustained visible damage to its exterior and interior, though the extent of structural impact has not been disclosed. SIM indicated that an investigation will continue to determine the origin of both fires and to evaluate any potential violations of fire safety regulations.

Residents in the vicinity were advised to stay clear of the area while emergency crews completed their work. The department also reminded businesses in industrial zones to review fire prevention measures and maintain functional fire suppression systems. The second fire within a brief period has drawn attention to the need for diligent oversight of industrial properties in the Lachine area.

SIM will release further information as the investigation proceeds, and authorities will consider any necessary actions based on the findings.
