Household Hazardous Waste

The County of Lambton, in conjunction with Clean Harbors Canada Inc., hosts several HHW collections events each year. The events give Lambton County residents an opportunity to properly dispose of potentially dangerous waste from their homes and protect our environment at the same time. If hazardous products are thrown in with the regular garbage, it can injure sanitation workers and cause long-term environmental problems.

Bring your household derived hazardous wastes to the special depot, and it will be dealt with by experts, at no cost to you!

Household Hazardous Waste collection events

HHW collection events take place at the Clean Harbors Canada Inc. site, 4090 Telfer Road in St. Clair Township in March, April, May, June, September, and October. 

Three mobile events are also scheduled for each year - one in Sarnia (June 13, 2026), one in Petrolia (Oct. 15, 2026), and one in Lambton Shores (Oct. 17, 2026).

To help make drop-off faster and easier, please package your waste items in disposable cardboard boxes, bags or containers if possible. Site staff will unload your waste in these packages and they will not be returned.

Upcoming event dates

What is accepted?

Sharps (hypodermic needles) and fluorescent lightbulbs are also accepted.

For safety reasons, please separate lithium batteries from all other battery types prior to drop-off.

Items NOT accepted include: PCBs, radioactive wastes, tires, explosives (fireworks, flares and ammunition), electronics, or asbestos.

We do not accept commercially, industrially, or agriculturally generated hazardous waste at these events. We do not accept containers larger than 20 litres or weighing more than 25 kg (55 lbs) at these events.

Read the Household Hazardous Waste flyer for additional details on what is and is not accepted at these events. 

Expired marine flares

Clean Harbors will not accept expired flares through the County's HHW program, as explosives are on the list of unacceptable items.

Flares (pyrotechnics) are only valid for four years from the manufacture date, which is stamped on each flare.

Lambton OPP recommends boaters keep expired flares in a sealed plastic bag beneath new flares. These expired flares may still work in a time of emergency, although they may have lost some of their certified range. They will provide a back-up, should the new flares fail to attract the attention of others in an emergency.
