The Municipal Hazardous or Special Waste (MHSW or Orange Drop) Program operated by the industry funding organization Stewardship Ontario (SO) allows Ontario residents to safely dispose of household products that require special handling, such as propane tanks and oil filters. Industry stewardship organizations are responsible for recovering additional hazardous waste products, including automotive materials; paints and coatings; pesticides, solvents and fertilizers; and proprietary carbon dioxide cylinders.

MHSW Program wind up


On April 12, 2018, the Minister of the Environment, Conservation and Parks directed SO to wind up the MHSW Program to enable the transition of hazardous or special materials to the individual producer responsibility (IPR) regulatory framework outlined in the Resource Recovery and Circular Economy Act, 2016 (RRCEA).

The IPR regulatory framework makes producers accountable for their products and packaging once consumers are finished with them; sets mandatory and enforceable requirements for resource recovery; and gives producers choices for resource recovery services in a competitive market.

The operation of the MHSW Program for all designated materials will cease on September 30, 2021, and starting October 1, 2021, these materials will be subject to IPR requirements under the RRCEA. The program for single-use batteries wound up on June 30, 2020, and on July 1, 2020, batteries were transitioned to the IPR regulatory framework outlined in the Batteries Regulation issued under the RRCEA. Visit our Batteries program page for more information.

The MHSW Program had previously been directed to wind up on June 30, 2021, but in April 2021, the wind-up date was extended to September 30, 2021, by Minister’s direction. SO and the Authority will be conducting consultations on the extended wind-up. For more information about the consultations, visit SO’s website and the Authority’s current consultations page.

Wind-up plan

Under the Waste Diversion Transition Act, 2016 (WDTA), the Authority is responsible for overseeing the orderly wind up of current waste diversion programs and the industry funding organizations responsible for managing those programs.

On December 27, 2019, the Authority approved SO’s MHSW Wind-up Plan with conditions. Read the approval letter. In 2020, the Authority approved two addendums to the Wind Up Plan related to the distribution of residual funds and surplus funds that SO was directed by the Minister to develop. For more information about the MHSW consultations, visit the past consultations page.

Until the wind-up on September 30, 2021, SO will continue to operate the MHSW program without disruption. This includes the operation of the industry stewardship plans managed by the Automotive Materials Stewardship, Product Care Association and SodaStream.

Proposed Hazardous and Special Products Regulation

The Government of Ontario is developing a new regulation for Hazardous and Special Products (HSP) that will support the transition of the MHSW program to a new system that makes producers individually accountable and financially responsible for their products at end-of-life.

The Authority will be the regulator mandated by the Government of Ontario to enforce the HSP regulation requirements when it takes effect on October 1, 2021.

Further information about the regulation is available on the Environmental Registry of Ontario notice.
