This year, the Public Works Department will provide collection services for Household Hazardous Waste (HHW) such as corrosive, flammable or poisonous materials, by offering 9 free one-day events from April 24, 2022 through to October 23, 2022. The City has added locations at the Rideau Carleton Casino, the Michael Street Snow Dump, and the Canadian Tire Centre for 2022.
Note that event dates are subject to change. The schedule will be updated as needed on Ottawa.ca. Residents are also encouraged to consult the Waste Explorer tool for a full list of items accepted at the HHW events. In addition, the Waste Explorer provides a list of retailers throughout the city that accept household hazardous waste materials at any time, and will continue to be updated as more sites are identified through the adaptation of the Hazardous and Special Products Regulation (ACS2021-PWE-SWS-0004) by producers of household hazardous waste materials.
