This page presents data about household hazardous material recycling in Ontario, including the weight of materials supplied and recycled year-⁠over-⁠year.

Ontario’s recycling laws require businesses to report this data to RPRA, as the regulator responsible for enforcing these laws. The reporting of this information helps ensure household hazardous materials are properly collected and recycled—and that valuable resources are kept out of landfill.

RPRA updates this page annually. The data reflects what was reported as of January 30, 2026, and is subject to change.

Businesses that supply household hazardous materials in Ontario must report the total weight they supply into the province each year to RPRA. The household hazardous materials you buy at a retail store—like paint or antifreeze for your car—are a part of the total amount that businesses supplied into the province.

Note: 2018 is the first year of household hazardous materials supply data that was required to be reported.

When you drop off used household hazardous materials like a paint can or antifreeze container at a recycling location, they’re collected and sent to facilities where they are sorted and processed or broken down into different materials, or safely disposed of.

Businesses that supply household hazardous materials in Ontario are required to collect and recycle household hazardous materials once consumers are finished with them and report the weight of materials they recycle each year.
