How to Handle Hazardous Materials when Scrapping a Car in Canada

Where it is crushed and shredded, hazardous materials must be removed before destruction. This process is known as vehicle depollution, involves a certified auto recycler draining engine oil, coolant, brake fluid, transmission fluid, and fuel; safely removing the car battery, tyres and refrigerants; and safely disposing of or neutralising airbags and mercury switches in accordance with federal and provincial laws. Even attempting to deal with these materials yourself without the proper equipment is dangerous and illegal in most provinces. 

Every single vehicle on the road holds a surprising amount of toxic materials. These substances don’t just “go away” when a car reaches the end of its life, they become scrap car hazardous materials that can leach into soil, groundwater, and air if not properly managed.

A single end-of-life vehicle (ELV) may include each of the following ten different categories of hazardous waste:

• Engine oil, transmission fluid, brake fluid and power steering fluid
• Coolant (antifreeze) containing ethylene glycol
• Fuel (gasoline or diesel)
• The CFCs and HFCs used in air conditioning refrigerants
• Lead-acid batteries
• Rubber Tires
• Mercury switches (op: 2003) (trunk, hood, and ABS systems in pre-2003 cars)
• Airbags (classified as explosive devices)
• Asbestos (in old brake pads)
• Catalytic converters containing platinum-group metals

All together, this hazardous vehicle waste poses a grave environmental and public health risk. That is exactly why Canada has created such a solid regulatory framework around it.

End-of-life vehicles in Canada must undergo a process called vehicle depollution, where all hazardous fluids and components are removed before crushing, shredding or dismantling the vehicle for parts.

The standard is the Canadian Auto Recyclers’ Environmental Code (CAREC), which the Automotive  Recyclers of Canada (ARC) developed to provide a national/generic best-practice guide for safe and lawful recycling of end-of-life vehicles. Under CAREC, certified recyclers are required to adhere to a documented depollution checklist draining fluids, neutralising explosive components and routing reclaimed materials into approved stewardship programs.

That means you, the car owner, are not responsible for properly disposing of your junker, it’s up to the recycler. It is your responsibility to pass on your car to a CAREC-certified facility.

Car Battery Disposal

One of the most regulated areas of auto recycling in Canada is how to dispose of car batteries. Lead-acid batteries hold sulfuric acid and heavy metal lead plates, both of which are acutely toxic if released into the environment. Certified recyclers must remove and place batteries in dedicated, sealed containers before they ship the units to approved battery recyclers. Battery deposit-return programs in most provinces help pay for proper processing. Never dispose of a car battery in ordinary waste.

Used Oil Disposal Canada

Used oil disposal in Canada is regulated by both federal and provincial governments. Depollution also includes the separate collection of engine oil, transmission fluid and brake fluid which must be recycled in licensed used oil re-refiners or energy recovery facilities. Used oil management programs exist for Ontario, Quebec and British Columbia (the responsible groups in Quebec are Product Care and Éco Peinture) and these attempt to ensure the recovered used oil is re-refined into lubricants that can be of use, not incinerated or landfilled. Discarding used oil through drains or on the ground is a criminal act under the Canadian Environmental Protection Act.

Tyre Disposal Canada

Tire recycling Canada is regulated by Extended Producer Responsibility (EPR) programs across provinces. Tires from ELVs are stripped off, taken to registered collectors who grind them into crumb rubber for playground cover or fuel-derived products before an ELV is crushed. In Ontario, the compliant tyre recycling program is managed by the Ontario Tire Stewardship (currently in operation via Circular Materials Ontario). All provinces have a sizable fine for dumping tires illegally.

Refrigerant Removal

Most car air conditioning systems are charged with ozone-depleting refrigerants (commonly R-12 in older vehicles) or hydrofluorocarbon refrigerants (R-134a in post-1994 models). Both must be recovered with certified recovery gear before any processing can happen to the vehicle. Under Canadian Environmental Protection Act (CEPA) federal regulations, venting refrigerants into the atmosphere is prohibited.

Mercury Switches

Mercury-tilt switches in convenience lighting and ABS sensor circuits are often found in older vehicles (built before 2003). The program, governed by the Automotive Recyclers of Canada (ARC), assists certified recyclers in finding and removing these switches for safe mercury recovery. This is an important but easily forgotten element of responsible auto recycling in Canada.

Airbags and Asbestos

Undeployed airbags are considered explosive devices, and they have to be deployed in a controlled setting or sent to special disposal facilities. Asbestos-containing brake pads — which are still present in some older imported vehicles, must be disposed of according to stringent Occupational Health and Safety Act (OHSA) protocols before any shearing, crushing or shredding can happen. ​

Ontario has one of the most comprehensive legislative frameworks in Canada for management of vehicle end-of-life. Ontario Car Scrapping regulations are governed primarily by:

• Ontario Regulation 85/16 – Part II Registrations. 2 of the Environmental Protection Act for End-of-Life Vehicle waste disposal sites.
• Ontario Regulation 347 – General Waste Management Regulation, which categorizes hazardous waste and how it needs to be handled
• Ontario Regulation 245/11 – Environmental Activity and Sector Registry (EASR) requirements for ELV processors​

Under these rules, no one can crush, shear or shred an ELV unless all the designated hazardous materials fluids, batteries and tires as well as mercury switches – have been extracted and documented first. Treatment Facilities must register with the Ministry of the Environment and keep detailed and updated lists of all materials removed, along with their disposal pathways.

Junkyards do not all function the same. So, when searching for responsible auto recycling Canada, here is what you need to know:

✅ CAREC Certification – guarantees that the recycler respects national depollution standards

✅ Registration at the provincial level – this is a requirement in Ontario, where recyclers must be registered under the Environmental Activity and Sector Registry (the EASR)

✅ Removal of fluids has been documented, ask for a de-pollution checklist or certificate.

✅ Transparent pricing — a responsible recycler will pay you fairly for your vehicle
