The Bureau de l'inspecteur général de Montréal (BIG) announced a major enforcement sweep in September 2026 targeting illegal hiring and undocumented workers in the city's waste-collection sector.

The investigation uncovered that many waste-collection subcontractors operated without proper registration and relied on off-the-books labor, often using false identities. This created safety and legal risks.

BIG officials said the sweep would involve inspections, fines, and possible revocation of permits for firms found in violation. The agency coordinated with municipal authorities and labor inspectors to identify non-compliant operations.

The waste-collection system in Montreal has historically depended on subcontractors to handle residential and commercial garbage. Over time, some firms began bypassing labor regulations, hiring workers who were not documented and avoiding payroll taxes. This practice left workers without legal protections and raised concerns about workplace safety.

The enforcement action aims to restore compliance with labor laws and ensure that waste-collection services meet safety standards. BIG warned that any subcontractor continuing to employ undocumented workers could face significant penalties.

The move comes as part of broader efforts by city officials to tighten oversight of essential services. By targeting the illegal labor network, the bureau hopes to protect both workers and residents while reinforcing the integrity of Montreal's waste-management infrastructure.

Authorities indicated that workers found to be employed under false identities may be subject to immigration reviews and could be required to regularize their status. The bureau also offered resources to help affected individuals understand their rights and access assistance.

The enforcement sweep is expected to conclude in the coming weeks, after which BIG will publish a report detailing violations and recommended measures for the sector. City officials said they will monitor compliance closely to prevent a recurrence of illegal hiring practices.
