Handling hazardous materials when scrapping a car means draining 5 core fluids, removing the battery, and disabling the airbags before a licensed recycler crushes the shell. Ontario law requires this depollution sequence at every registered facility in 2026.
Your vehicle holds 6 categories of hazardous substances: engine fluids, the lead-acid battery, refrigerant gas, airbag propellant, mercury switches, and catalytic converter residue. A trained technician removes each substance in a fixed order to prevent leaks and soil contamination.
This guide covers the exact removal steps, the Ministry of the Environment, Conservation and Parks (MECP) rules that apply in Ontario, and the extra precautions electric vehicle (EV) battery packs demand. Following this sequence before pickup day reduces fines, spills, and delays.
What Hazardous Materials Does Your Vehicle Contain?
Your vehicle contains 6 hazardous material categories: engine fluids, the battery, refrigerant gas, airbags, mercury switches, and catalytic converter residue. Each category demands a separate removal method and disposal path.
Fluids sit at the top of this list because they leak fastest once a vehicle sits idle for weeks. Metals rank second because lead, mercury, and cadmium accumulate in soil and groundwater over years, not days.
5 Fluids That Require Removal Before Scrapping
To remove fluids before scrapping, drain 5 specific liquids: engine oil, transmission fluid, brake fluid, coolant, and gasoline. Power steering fluid counts as a sixth liquid in vehicles built after 1999.
One litre (0.26 gallons) of engine oil contaminates up to 1,000,000 litres (264,000 gallons) of groundwater. This ratio explains why Ontario treats used oil as a regulated liquid industrial waste stream.
3 Metals That Pose Environmental Risk
Your vehicle carries 3 metals that pose the highest environmental risk: lead, mercury, and cadmium. Lead sits inside the battery plates and the wheel balance weights.
Mercury appears in convenience-light switches and in anti-lock braking system (ABS) sensors on vehicles built before 2003. Cadmium coats electrical contacts and several plated bolts under the hood.
How to Drain Fluids Before Scrapping a Car
To drain fluids before scrapping a car, position the vehicle on a flat, ventilated surface with 6 feet (1.8 metres) of clearance on each side. Remove the oil plug, transmission plug, and radiator cap in sequence.
Collect each fluid in a separate, sealed container rated for automotive waste. Use 5-gallon (19-litre) containers with tight lids for engine oil, coolant, and transmission fluid.
Label every container with the fluid type and the date you drained it. Never mix used oil with coolant or brake fluid, since mixed fluids become harder and costlier to process.
Ethylene glycol, the toxic ingredient in most coolant brands, tastes sweet to pets and wildlife. Store drained coolant away from driveways and storm drains at all times.
How to Remove and Dispose of a Car Battery Safely
To remove a car battery safely, disconnect the negative terminal first, then the positive terminal, then lift the battery straight out of its tray. Reversing this order risks a short circuit and a spark near battery gases.
A lead-acid battery contains sulfuric acid and roughly 18 pounds (8 kilograms) of lead per unit. Acid burns skin on contact, and lead poisons soil when a casing cracks.
Tools You Need for Safe Battery Removal
You need 4 tools for safe battery removal: insulated gloves, safety goggles, a socket wrench set, and a battery carrier strap. Baking soda mixed with water neutralizes small acid spills on contact.
Keep a fire extinguisher rated for electrical fires within 10 feet (3 metres) of the work area.
Where to Recycle a Lead-Acid Battery in the GTA
You can recycle a lead-acid battery at most auto parts retailers across the Greater Toronto Area (GTA), including major chains and independent shops. Many retailers pay a small deposit refund per battery.
A licensed scrap car buyer removes and recycles the battery for you as part of standard pickup, so you skip the drop-off trip entirely.
How to Handle Airbags and Pyrotechnic Devices
To handle airbags safely, leave undeployed units inside the vehicle and let a licensed recycler perform controlled deployment. An undeployed airbag qualifies as an explosive device under Canadian transport law.
Each airbag module contains a pyrotechnic igniter and sodium azide (NaN3), a chemical compound that generates gas in milliseconds when triggered. Cutting into wiring near an airbag module risks accidental deployment and serious injury.
Vehicles involved in collisions carry the highest airbag risk because sensors may sit partially triggered after impact. If your car needs accident damaged vehicle pickup, a certified technician inspects and disarms every airbag module before towing.
What Ontario Regulations Govern Hazardous Car Waste?
The Ministry of the Environment, Conservation and Parks (MECP) regulates hazardous car waste in Ontario under Regulation 347 and Ontario Regulation 85/16. Both rules apply to every end-of-life vehicle (ELV) processed in the province.
Regulation 347 classifies drained automotive fluids as liquid industrial waste. Ontario Regulation 85/16 sets registration and reporting duties for ELV processing sites across Ontario.
MECP Requirements for Licensed Recyclers
A licensed recycler must register on the Environmental Activity and Sector Registry (EASR) before accepting end-of-life vehicles. This registration confirms the facility meets MECP spill-prevention and drainage standards.
Recyclers must also submit a depollution notice with every batch of crushed vehicles shipped for metal recovery.
Storage Limits Under Regulation 347
Regulation 347 limits wet component storage to 24 months maximum. A wet component means any removed part that still holds fluid, such as an engine, transmission, or radiator.
Facilities that exceed this storage limit face fines starting at several thousand dollars per violation.
How to Dispose of Mercury Switches and Refrigerant Safely
To dispose of mercury switches safely, a technician extracts convenience-light and ABS switches before the vehicle reaches the crusher. Mercury travels through drainage systems and settles in fish tissue for decades.
Refrigerant recovery follows a separate path. A certified technician recovers R-134a or HFO-1234yf gas using a sealed recovery machine rather than venting it into the atmosphere.
Venting refrigerant violates federal environmental law and damages the ozone layer. Fines for illegal venting reach thousands of dollars per incident in Canada.
How to Handle EV and Hybrid Battery Hazards When Scrapping a Car
To handle EV and hybrid battery hazards, isolate the high-voltage system before any dismantling begins. Standard mechanics without high-voltage certification cannot legally disconnect these packs in Ontario.
Risks of Damaged Lithium-Ion Battery Packs
A damaged lithium-ion battery pack risks thermal runaway, a chain reaction that raises internal temperature past 1,000°F (538°C). This reaction can reignite hours or days after the initial impact.
Collision-damaged EV packs require 48 hours of monitored storage before a recycler moves them indoors.
Certified EV Battery Handlers in Ontario
Only certified technicians handle battery packs rated above 60 volts under Ontario workplace safety law. These specialists use insulated tools rated for 1,000 volts and infrared cameras to check for heat spikes.
Your vehicle’s catalytic converter also holds recoverable metals like platinum, palladium, and rhodium. A catalytic converter buying service safely extracts these metals alongside battery components during teardown.

Do airbags explode during the scrapping process?
No, a licensed recycler disarms every airbag through controlled deployment before dismantling starts.
How long can a scrapyard store hazardous parts?
24 months maximum, based on the wet component storage limit set under Regulation 347.
Can you scrap an electric vehicle with a damaged battery?
Yes, but only a certified high-voltage technician can isolate and remove a damaged EV battery pack.
