Toronto, Ontario requires multiunit residential properties to participate in organics diversion programs and provide access to composting/green-bin services for residents.

For the City’s operational guidance on multi-residential organics programs see the official apartment building organics page City of Toronto - Apartment building organics[1].

Penalties & Enforcement

The City enforces organics and waste requirements through municipal enforcement teams and Solid Waste Management Services. Specific monetary fines, escalation policy and non-monetary sanctions are set out in the City’s enforcement guidance and applicable municipal by-laws or compliance notices where published; where a figure or procedural detail is not shown on the cited page it is noted below.

  • Monetary fines: not specified on the cited page for multiunit organics; the City’s enforcement pages list penalties by offence category on a case-by-case basis.[2]
  • Escalation: the City may issue warnings, orders to comply, and subsequent fines for continued non-compliance; exact amounts and repeat-offence schedules are not specified on the cited guidance pages.
  • Non-monetary sanctions: orders to remedy, mandatory compliance timelines, seizure or removal of improperly stored materials, and court proceedings are possible where by-law orders are not followed.
  • Enforcer and inspection: Solid Waste Management Services and Municipal Licensing & Standards carry out inspections and enforcement; complaints and inquiries are handled through official City contact pages and 311 where applicable.[2]
  • Appeals and review: appeal or review routes depend on the specific order or ticket; the cited pages do not list a single consolidated appeal timeline for multiunit organics enforcement and instead point to standard by-law review procedures (not specified on the cited page).
  • Defences and discretion: inspectors may consider bona fide efforts to comply, documented transition plans, or active participation in City diversion programs as mitigating factors; permit or variance pathways are handled per municipal processes and are not specified on the organics guidance page.
If you receive a notice, follow the compliance timeline precisely and contact the listed City officer immediately.

Applications & Forms

Most multiunit composting requirements are implemented through service agreements and property-level operational changes rather than a single application form. Specific forms or applications for exemptions or service changes are not published on the organics guidance page; property owners should contact Solid Waste Management Services or Municipal Licensing & Standards to request forms or to confirm whether an application is required.[2]

Practical compliance steps for property owners

  • Register or confirm organics collection service with the City or contracted hauler and update service agreements as needed.
  • Install appropriate indoor and outdoor organics containers with City-compliant signage and schedule tenant access.
  • Maintain records of tenant communications, training sessions and service invoices to demonstrate good-faith compliance.
  • Respond promptly to complaints and inspection notices, remedying identified issues within the timelines specified by the City.
Clear labeling and tenant education are among the most effective measures to reduce contamination in organics streams.
