Quick answers

Can you insure a modified car in Canada?

Often yes. Many modified cars can be insured, but you should disclose modifications before installation and confirm (1) eligibility and (2) how aftermarket parts will be covered and valued.¹

Do modifications automatically increase insurance?

Not always. Some modifications increase repair cost, theft attractiveness, or performance risk and can raise premiums. Others have little pricing impact but still need to be disclosed to avoid claims disputes.

Will insurance cover aftermarket parts if you crash?

Sometimes, but do not assume full coverage. Many policies settle based on the vehicle as described in the contract, and aftermarket or custom equipment may require specific coverage or documentation to be paid as you expect.

What happens if you do not tell your insurer about mods?

Non-disclosure can create claim disputes and can lead to reduced payouts or denial depending on the facts and policy terms. The practical fix is to disclose now, provide documentation, and ask for written confirmation that the policy reflects your vehicle.

Do you need an inspection or appraisal?

It depends on the province, insurer, and the value or type of modification. Some insurers request photos, receipts, or an appraisal for higher-value builds or agreed value coverage. In Ontario, some appraisal providers publicly list pricing around $149 or $150 plus HST for insurer requested or classic style appraisals (pricing varies by provider and vehicle).¹⁰¹¹

Should you increase liability limits for a modified car?

Many drivers choose higher limits for peace of mind, and Ontario guidance notes you can purchase higher liability limits and increased accident benefits coverage.⁶

Why modifications change insurance

Modifications affect insurance because they can change risk and cost. Insurers generally care about three questions:

• Eligibility: will the insurer accept the vehicle at all with the declared modifications?
• Coverage: what exactly will be paid for aftermarket parts in a partial loss or total loss?
• Pricing: how do repair costs, theft risk, performance potential, and usage affect the premium?

Treat modified-car insurance as a coverage design problem first, then a price shopping problem second. Confirm eligibility and settlement terms before you compare quotes.

Before you modify: confirm these items first

The most expensive mistake is installing parts and assuming the policy will adapt automatically. Even when an insurer continues to renew a policy, that does not guarantee the modifications are covered the way you think. Many disputes start with “I will tell them later.”

Questions to ask and get answered in writing

• Eligibility: Will you insure this vehicle with these modifications, or do I need a specialty policy?²
• Parts coverage: Are aftermarket parts covered automatically, capped, or excluded unless scheduled?
• Settlement basis: For damaged modifications, do you pay OEM equivalent, aftermarket equivalent, depreciated value, or an agreed value?
• Documentation: Do you need receipts, install invoices, photos, an appraisal, or an inspection?
• Usage: Is the car used for commuting, business, delivery, rideshare, or track events, and are those uses covered?
• Restrictions: Are there conditions to keep coverage valid (professional install, certain parts excluded, ride height limits, etc.)?

What counts as a modification for insurance

For insurance purposes, a modification is typically any change from factory specifications that can affect value, performance, handling, theft attractiveness, repair cost, or how the vehicle is used. That includes performance upgrades and “cosmetic” changes that raise replacement cost.

Examples that commonly matter to insurers

• Performance: ECU tunes, turbo or supercharger kits, intake and exhaust changes, engine swaps.
• Suspension and fitment: lift kits, lowering springs, coilovers, spacers, oversized wheels and tires.
• Body and exterior: widebody kits, aftermarket bumpers, wraps, custom paint, lighting changes.
• Brakes: big brake kits, aftermarket calipers, rotors.
• Interior and electronics: high-value audio, custom seats, roll cages, dash electronics.
• Security: trackers, immobilizers, kill switches (often helpful, still worth disclosing).

Common modifications and what insurers ask

Insurers usually focus on changes that alter repair severity, loss frequency, theft risk, and vehicle value. Use the categories below to build a clear disclosure list you can email to your broker or insurer.

Performance modifications

Tunes, forced induction, engine swaps, and major intake or exhaust work are among the most likely to trigger underwriting review or a move to a specialty market.² If you plan performance upgrades, confirm eligibility before you book the install.

Suspension wheels and tires

Wheel and tire fitment and ride height changes can affect handling and repair costs. Keep documentation that shows what was installed and whether it was professionally installed and aligned.

Cosmetic and body modifications

Wraps, paint, and body kits can increase replacement costs. Lighting changes can raise road legality issues depending on local rules. Insurance does not enforce traffic law, but illegal equipment can complicate inspections and claims.

Audio electronics and interior builds

High-value audio and custom interior work is where payout gaps show up most often after theft or total loss when equipment was not declared, documented, or covered as custom equipment.

Province rules and public vs private insurance

Auto insurance is regulated provincially in Canada, and mandatory coverages differ by province and territory. The Insurance Bureau of Canada provides an overview of commonly required coverages where you live and notes that requirements can change, so confirm locally.⁴

In addition, some provinces operate public auto insurance for basic coverage while others rely on private insurers, which can affect where you buy optional coverages and how certain claims processes work. Confirm how your province handles basic and optional coverage before you shop.

Mandatory vs optional coverages

Modified vehicles can increase the financial stakes of a claim, especially for repair cost and theft exposure. Review your declarations page to confirm your mandatory coverages and then decide what optional coverage makes sense for your build and your risk tolerance.

Ontario example: optional coverages you may see

Ontario consumers can add optional coverages and endorsements, including family protection (OPCF 44R) and other options described by FSRA.⁵ FSRA also notes you may purchase higher liability limits and increased accident benefits coverages based on your needs.⁶

Rate benchmarks and methodology

Pricing for modified cars depends on your city, driving record, vehicle, usage, and the type and value of modifications. To provide grounded benchmarks, we include:

• Ontario average premiums: FSRA published averages for Ontario, the GTA, other urban, and rural regions.
• Canada written premium benchmarks: Statistics Canada published average written premium figures by province groupings as of December 2024 and notes averages should be used with caution.

How to insure a modified car step by step

If you want coverage that responds in a claim, the process is mostly documentation and clarity. Many insurers can insure modified vehicles, but you should inform them of modifications and confirm coverage and settlement terms before you rely on it.¹

Step 1: build a complete modification inventory

• List every change from stock, including wheels, tint, lighting, audio, and security devices.
• Note install date, installer or shop, and the approximate cost (use receipts where possible).
• Add photos: wide shots and close ups of key parts.

Step 2: disclose and request underwriting confirmation

Send the inventory to your broker or insurer and ask them to confirm eligibility and how modifications are covered and valued. If the answer is verbal, request an email summary or updated documents showing endorsements or scheduled items.

Step 3: choose the right coverage structure

Depending on your province and insurer, you may be looking at a standard policy with an endorsement for custom equipment, or a specialty policy designed for modified vehicles. Broker guidance commonly notes many modifications may require a different insurer willing to cover a modified vehicle.²

Step 4: confirm usage and exclusions

Many personal auto policies exclude racing, stunting, or track events. Even casual track days can be excluded depending on wording. If you participate in track activity, ask what is excluded and whether separate coverage exists for that activity in your province.

Step 5: maintain documentation and update the policy

Modified cars evolve. Every time you add parts that materially affect value, performance, or theft risk, update your mod list and notify your insurer or broker. Set a recurring reminder every 6 to 12 months to keep your policy aligned with the vehicle you actually drive.

Claims and settlement for aftermarket parts

Claims are where modified-car insurance either works smoothly or becomes frustrating. The key is settlement. Ask for a plain-language explanation of how your insurer settles:

• Partial losses: repairable claims where a modified part is damaged.
• Total losses: write-offs or theft claims where market value and documentation drive the payout.

Partial loss: repairable claim

If your bumper, wheels, suspension, or audio equipment is damaged, settlement depends on policy terms. If modifications were not declared or covered, an insurer may pay stock-equivalent parts or apply limitations.

What to do next: confirm whether your policy allows aftermarket replacement and whether your insurer can limit the settlement to like kind and quality. Ask about repair shop choice rules in your province.

Total loss: the value gap risk

In a total loss, settlement often focuses on actual cash value or market value. Modifications are not always fully reflected unless specifically insured or supported by accepted documentation. If your build value is significant, ask whether an appraisal is accepted and whether you can schedule custom equipment to reduce the payout gap.

Theft claims: documentation matters

Theft is where receipts and photos are critical, especially for removable items and high-value electronics. Store copies of receipts and photos off your phone so you can access them after a theft.

If your insurer says no

If your insurer will not insure the vehicle with your modifications, avoid driving uninsured while you shop options. Broker guidance suggests modified vehicles may require a different market willing to accept the risk.²

Option 1: move to a specialty market through a broker

Specialty insurers may be more comfortable with performance modifications and declared custom equipment but often require stricter documentation and sometimes inspections or appraisals.

Option 2: adjust the build to fit standard underwriting

Sometimes one modification is the barrier. Ask the insurer or broker which specific modification triggered the decline and whether reverting it to stock restores eligibility.

Option 3: separate coverage for excluded uses

If your issue is usage, you may need separate coverage for that activity rather than trying to force it into a personal auto policy.

FAQs

Do I need to tell my insurer about cosmetic modifications like a wrap or wheels

Usually yes if the change materially affects value or replacement cost. Disclose the item and ask whether it needs to be endorsed or scheduled to be included in claim settlement.

Will my insurer cancel me for modifying my car

Outcomes vary by insurer and province. Some insurers continue coverage with conditions while others decline modified vehicles and require you to move to a different provider.² Disclose early and confirm eligibility before installing major modifications.

Are performance tunes and engine swaps insurable

Sometimes, but they are among the modifications most likely to trigger underwriting review or a move to specialty markets.² Provide a detailed parts list and installation documentation and ask whether inspection or appraisal is required.

Does public auto insurance change how modifications are covered

It can. Because mandatory coverages and how optional coverages are purchased vary by province, confirm with your provincial insurer or broker how custom equipment is insured where you live.⁴

Should I increase my liability limit because my car is modified

Many drivers consider higher limits, but what is appropriate depends on your assets, driving patterns, and risk tolerance. Ontario consumer guidance notes you may purchase higher liability limits and increased accident benefits coverage based on your needs.⁶

If I did not disclose mods and I already had a claim what should I do now

Do not guess. Talk to your insurer or broker and disclose the modifications. Document everything and ask how to update the policy so future coverage aligns with the vehicle you drive.
