The City of Montreal announced that its biweekly residual waste collection program will be rolled out to four additional boroughs in the fall of 2026. The expansion adds Ahuntsic‑Cartierville, Villeray‑Saint‑Michel‑Parc‑Extension, Pierrefonds‑Roxboro and L’Île‑Bizard‑Sainte‑Geneviève to the list of areas receiving the service.

Residents of the four boroughs will begin receiving residual waste pickups every two weeks, following the schedule already in place in other parts of the city. The city indicated that the change will be implemented as part of its broader waste‑management strategy, aiming to standardise collection frequencies across Montreal.

The decision comes after the program was piloted in the Mercier–Hochelaga‑Maisonneuve borough, where it generated public debate. Critics in that borough raised concerns about the reduced frequency of pickups, while supporters pointed to potential benefits such as lower emissions from collection trucks.

City officials noted that the pilot in Mercier–Hochelaga‑Maisonneuve provided valuable data on how the biweekly schedule functions in an urban setting. The information gathered is being used to inform the rollout in the new boroughs, ensuring that operational logistics and resident needs are addressed.

By extending the biweekly residual waste collection to four more districts, Montreal aims to create a more uniform waste‑service framework citywide. The move reflects the municipal government's intent to apply lessons learned from the earlier pilot while continuing to manage solid waste efficiently.

The expansion is scheduled for the upcoming fall season, with the city planning to coordinate with local neighbourhood committees to communicate collection dates and any required adjustments for households. No additional details on cost or service modifications were released at the time of the announcement.
