Quebec’s biggest landfill, the Terrebonne megasite, is being enlarged to handle more than 1.2 million tonnes of additional waste, officials announced Wednesday morning. The urgent expansion aims to increase the site’s capacity as the province confronts rising volumes of municipal solid waste.
The Terrebonne megasite, located in the city of Terrebonne, has long served as the primary disposal location for the region’s refuse. The new phase of development will add space sufficient for the stated 1.2 million tonnes, a figure that reflects the latest assessments of waste generation trends across Quebec.
Authorities say the expansion is a response to a measurable increase in waste streams that has outpaced the existing capacity of the landfill. By enlarging the megasite, the province seeks to maintain uninterrupted service for municipalities that rely on the facility for safe and regulated disposal.
Work on the enlargement began in early 2026 and is proceeding under an urgent timetable to meet the projected demand. The project involves extending the landfill’s perimeter and upgrading associated infrastructure to accommodate the additional tonnage while adhering to environmental and safety standards.
The move underscores the challenges faced by waste management systems as population growth and consumption patterns evolve. With the added capacity, the Terrebonne megasite will continue to function as Quebec’s primary landfill, supporting the province’s broader waste handling strategy for the foreseeable future.
