Catalytic converter theft remains one of the most expensive vehicle crimes in Canada, often leaving drivers with repair bills worth thousands of dollars.

Read on to learn whether your insurance covers catalytic converter theft, which endorsements are worth considering, how deductibles affect a claim, and what you can do to reduce the risk of becoming a target.

What is a Catalytic Converter?

The catalytic converter is one of the most important components for controlling the harmful polluting emissions from combustion engines. Its main function is to convert the polluting gases produced by burning fuel into less harmful gases. This item is located under the vehicle, close to the exhaust system piping, right next to the oxygen sensor.

Does My Car Insurance Cover Catalytic Converter Theft?

Yes, if you have comprehensive, all-perils, or specified-perils coverage included in your auto insurance policy, catalytic converter theft is typically covered. However, comprehensive coverage is not mandatory in Canada.

If you live in an area with higher rates of theft or vandalism, you should think about whether this coverage is included in your policy before purchasing insurance. Your comprehensive deductible comes off any theft payout. Read the claims section below for a walkthrough of that math.

Why Do Thieves Steal Catalytic Converters?

Three things make converters a target: what’s inside them, how fast they can be cut free, and how hard they are to trace once they’re gone.

The metal of which it is made

Catalytic converter theft is increasing because these converters contain platinum, palladium, and rhodium. Rhodium is the most valuable of these metals, often trading at several times the price of gold, and is the primary driver behind the high black-market value of stolen converters.

Thieves sell stolen converters for between $150 and $1,400, depending on the model, while victims can face total replacement costs, including specialized sensors, labour, and potential repairs to exhaust piping, ranging from $2,000 up to $5,000.

The ease of theft

There’s no forced entry and no alarm-tripping door handle. A thief with a battery-powered reciprocating saw slides under the car, makes two cuts through the exhaust pipe, and is gone in a couple of minutes. You don’t need a jack on a high-clearance vehicle. Most thefts happen overnight in driveways, apartment lots, and commuter parking lots.

The inability to track the stolen part

Most converters do not have a marking or a number to identify which car it belongs to. For this reason, even if police recover it, it is almost impossible to identify the car to which it belongs. This flaw also makes it easier for thieves to sell converters on the black market, which also makes them difficult to trace.

What Cars are More Likely to be Targeted for Catalytic Converter Theft?

Converter thieves pick targets by access and payoff. High-clearance pickups, SUVs, and delivery vans can be slid under without a jack. Hybrids like the Toyota Prius are the textbook case because their converters carry a richer load of precious metals and stay in better condition, since the gas engine only runs part of the time.

How to Know If Your Catalytic Converter Has Been Removed?

The stolen catalytic converter will trigger a check engine light and loud roaring noises. While a clogged or failing converter can cause engine overheating due to exhaust backpressure, a stolen converter (which creates an open exhaust) will not typically cause overheating, though it will immediately impact fuel efficiency and vehicle performance.

Deductible Math: When is a Claim Worth it?

Compare the repair cost before you file. Comprehensive deductibles in Ontario commonly sit between $500 and $1,000, and the insurer only pays what’s left after yours comes off the bill:

Repair billInsurer pays
($500 deductible)
Insurer pays
($1,000 deductible)
$2,000$1,500$1,000
$3,500$3,000$2,500
$5,000$4,500$4,000

Keep in mind that filing a comprehensive claim can also potentially lead to a rate increase at your renewal, but that depends on your insurance company.

How Can I Protect My Vehicle?

The recommendations below will not prevent your converter from being stolen, but they will greatly reduce the likelihood of it happening.

Use secure parking

Although it seems like a common-sense recommendation, it is not so much in reality. Vandals often take advantage of the dark to commit this crime, so finding safe, well-lit areas to park your car is important. Also, consider parking inside the garage or near a wall or door so that they cannot squeeze under the vehicle.

Engrave your car’s VIN

The authorities recommend recording on the catalytic converter either your license plate number or your vehicle’s identification number, known as a VIN. In addition to helping authorities track down stolen parts and find the owners, this practice can make it much more difficult for a thief to sell the part.

Increase the alarm sensitivity

Most car alarms can be set to increase their sensitivity. This way, when the thief tries to get under or manipulate any part of your car, the alarm will go off, instantly warning you. You can refer to the manual to learn how to set it up.

Install an anti-theft shield or cage

Purpose-built hardware is the strongest deterrent on this list. A bolted or welded metal shield or β€œcat cage” over the converter, or a cable clamp tying it to the frame, turns a two-minute cut into a long, noisy job most thieves will not want to do.
