MHSW Program wind-up extended to September 30, 2021

On April 29, 2021, the Minister of the Environment, Conservation and Parks issued new direction to Stewardship Ontario (SO) to extend the deadline to wind up the Municipal Hazardous or Special Waste (MHSW) Program from June 30, 2021, to September 30, 2021. The 3-month extension follows from feedback the Minister received from stakeholders and applies to all designated materials except for single-use batteries, which already transitioned to the individual producer responsibility framework regulated by the Authority in June 2020.

SO will be hosting a consultation on necessary changes to the MHSW Wind-Up Plan reporting deadlines for stakeholders and update financial information in relation to the extension. The Amendments to the MHSW Wind-Up Plan webinar will be held Tuesday, May 18, 2021, from 10:00 a.m. to 11:30 a.m. Click here to register.

Stakeholders are invited to submit feedback on the content discussed during the consultation webinar up until Tuesday, May 25, 2021. Please email feedback to

SO is required to submit an amendment to the MHSW Wind-up Plan to the Authority for approval no later than May 31, 2021. The Authority is expected to approve the amendment no later than June 30, 2021.

All other elements of the wind-up plan for MHSW will remain unchanged except as necessary to implement the Minister’s direction.

The Government of Ontario is developing a new regulation that will detail the individual producer responsibility requirements for MHSW materials once the current program ends on September 30, 2021. Further information about the regulation is available on the Environmental Registry of Ontario notice.
