The Hazardous and Special Products Regulation is now in effect

As of October 1, 2021, following the wind up of the Municipal Hazardous or Special Waste (MHSW) Program operated by Stewardship Ontario on September 30, 2021, Hazardous and Special Products (HSP) producers are individually accountable and financially responsible for requirements set out under the HSP Regulation.

The HSP Regulation designates oil filters, oil containers, antifreeze, solvents, paints and coatings, pesticides, fertilizers, non-refillable pressurized containers, refillable pressurized containers, refillable propane containers and mercury-containing barometers, thermometers and thermostats under the new framework.


As of October 1, 2021, producers must:

  • Establish and operate a collection and management system (excluding producers of fertilizers)
  • Carry out promotion and education requirements (excluding producers of refillable pressurized containers and refillable propane containers)

By November 30, 2021, producers must:

  • Register with the Authority
  • Submit a report on their 2018, 2019 and 2020 supply data (excluding producers of fertilizers, non-refillable pressurized containers, refillable propane containers and mercury-containing barometers, thermometers and thermostats)

Whether or not you have registered, you must meet your collection, management, and promotion and education obligations starting on October 1.

Haulers, processors and disposal facilities

Haulers, processors and disposal facilities, sometimes referred to as service providers, support producers, or producer responsibility organizations (PROs) acting on their behalf, with fulfilling their obligations under the HSP Regulation.

The deadline for service providers to register with the Authority was August 31, 2021. If you are a service provider and have not yet registered, complete this registration form and email it as an attachment to

Producers, or PROs, can only rely on service providers who are registered with the Authority.

A PRO is a business established to contract with producers to provide collection, management and administrative services to help producers meet their regulatory obligations. It is up to the producer if they want to work with a PRO or meet their requirements without the services of a PRO.

As of October 1, 2021, HSP producers are responsible for collecting and managing their products when consumers discard them. A PRO that has entered into an agreement with a producer for collection, management or promotion and education services under the HSP Regulation has an independent obligation to meet the requirements that apply to that producer. PROs must ensure that collection, management, or promotion and education requirements, as applicable, are met for every producer they contract with.

Visit our HSP PRO webpage for more information on regulatory requirements for PROs.
