The County of Lambton, in conjunction with Clean Harbors Canada Inc., host 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.

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

Dates for 2020 are on the following Saturdays:

March 28 - CANCELLED due to COVID19 concerns April 25

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

Disposal of Expired Marine Flares
Flares (pyrotechnics) are valid only for four years from the date of manufacture, which is stamped on each flare.  Clean Harbors will not take expired flares through the County’s household hazardous waste program as explosives are one of the six (PCBs, commercial, infectious, radioactive, tires, explosives/ammunitions) unacceptable items.

Only Sarnia Police Services will accept expired flares at its location - 555 Christina Street North, Sarnia, ON.

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.
