Environmental Protection Quebec 4 Minutes Read · published May 26, 2026 Flag of Quebec · By Daniel Roy

Ahuntsic-Cartierville, Quebec requires proper handling of organic waste for multiunit housing to reduce landfill use and meet city diversion targets. This FAQ explains who must comply, required containers and signage, collection obligations, reporting and appeal routes for owners, property managers and syndicates of co-ownership. It also lists practical steps to start or improve composting, how to report non-compliance, and where to find official forms and contacts. Follow the borough and Ville de Montre9al instructions to avoid service interruptions and ensure collections meet local sorting standards.

Overview: Who must comply

Multiunit residential buildings (typically 4 units or more) are normally required to participate in the municipal organics collection program and to provide appropriate containers and signage for tenants. Property owners and managers are responsible for ensuring correct sorting at the source and access for curbside or shared-building collection.

Check your building governance documents to confirm whether the property manager or syndicate is responsible for waste services.

Practical requirements

Common obligations for multiunit buildings include provision of:

  • Designated indoor bins for food and other accepted organics.
  • Weatherproof outdoor or shared containers sized for collection frequency.
  • Clear tenant information and signage describing accepted items and contamination rules.
  • Arranged collection schedule with the borough or contracted service.

Accepted and prohibited materials

Accepted organics usually include food scraps, soiled paper and certain yard waste; plastics, glass, metal and non-compostable packaging are prohibited and must be set out for the proper stream. Always follow the current Ville de Montre9al acceptance list for details.[1]

Setting up service and tenant communication

  • Notify tenants in writing about the buildinge28099s organics program, accepted items and bin locations.
  • Provide a contact for collection issues and complaints to the borough or your hauler.
  • Keep records of sanitary inspections, collection schedules and tenant notices for at least one year.
Label indoor and outdoor bins in both official languages when possible.

Penalties & Enforcement

The municipal enforcement approach covers improper sorting, insufficient or missing containers, contamination, and failure to arrange required collection for multiunit properties. Specific monetary fines and penalty schedules are not listed on the general organics program pages and are therefore not specified on the cited page.[1]

  • Fines: not specified on the cited page.
  • Escalation (first/repeat/continuing offences): not specified on the cited page.
  • Non-monetary sanctions: orders to remedy, removal/seizure of non-compliant containers, requirement to implement approved diversion measures, and potential court action to enforce orders.
  • Enforcer: borough By-law Enforcement and the Ville de Montre9al waste management units; complaints and inspections are handled through borough services and 311 or the local borough contact.[2]
  • Appeals/review: specific appeal routes and time limits are not specified on the cited pages; follow the procedures listed on the enforcement or bylaw page when an order is issued.

Applications & Forms

There is typically no special provincial permit just to participate in organics collection; building owners should consult the borough for any required registration with their local collection contractor. No dedicated municipal form for multiunit compost registration is published on the general guidance page, or none is specified there.[1]

Common violations

  • Setting out non-accepted materials in organics containers.
  • Failure to provide indoor sorting containers and tenant information.
  • Missed or irregular collection due to inadequate outdoor container capacity.

Action steps for owners and managers

  • Review the Ville de Montre9al organics acceptance list and update tenant materials accordingly.[1]
  • Order or resize outdoor containers to match building generation rates and collection frequency.
  • Report collection problems or suspected illegal dumping to the borough or 311.
Keep a simple contamination log to show compliance efforts if enforcement inspects your building.
