The Quebec government announced on July 2, 2026 that it has authorized an emergency measure to raise the height of garbage piles at the province’s largest landfill in Terrebonne, a community north of Montreal. The temporary expansion is intended to keep the site operational while it approaches full capacity.
The Terrebonne site, which handles the bulk of Quebec’s municipal solid waste, is the province’s biggest landfill. By permitting taller waste stacks, the government aims to add a short‑term increase in storage volume without constructing new landfill cells. The approval applies only for a limited period until the site reaches its projected limit.
Officials said the landfill is expected to fill up within a year, prompting the emergency height increase to avoid an interruption in waste disposal services. The measure is described as temporary, allowing the province to maintain current operations while longer‑term solutions are evaluated.
Quebec’s waste management strategy relies on the Terrebonne facility as a central hub for the region’s refuse. With the site projected to reach capacity in less than twelve months, the government’s decision reflects a need to extend the landfill’s life span while alternative sites or capacity‑expansion projects are explored.
The height increase will be monitored by provincial environmental officials to ensure compliance with safety and environmental standards. Authorities will assess the stability of the taller waste piles and enforce any necessary controls to mitigate risks such as leachate production or fire hazards.
The temporary measure does not alter the long‑term plan to eventually replace the Terrebonne landfill with newer facilities or to increase recycling and waste‑reduction programs across the province. It simply provides an interim buffer as Quebec works toward a more sustainable waste‑management framework.
