he restomod scene in Canada is having a moment. Walk into any specialty shop from Victoria to Halifax, and you’ll find the same conversation happening: a customer wants their 1972 Datsun 240Z, their air-cooled 911, or their first-generation Bronco brought back to life — but with a Tesla drive unit under the hood and a lithium pack where the gas tank used to be.
For Canadian garages, this is a serious business opportunity. EV conversions of classic cars are no longer fringe — they’re a growing service category attracting collectors, environmentally minded enthusiasts, and a new generation of buyers who want vintage aesthetics without vintage maintenance headaches. But for shop owners scaling into this work, there’s a problem hiding in plain sight: the import compliance side of EV conversion kits is dramatically more complex than ordering traditional aftermarket parts.
You’re not just importing auto parts. Depending on what’s in the kit, you may be importing motor vehicles, dangerous goods, regulated battery components, controlled goods under import quotas, and items subject to multiple overlapping tariff regimes. Get the classification wrong and you’ll either overpay by thousands or trigger a CBSA detention that grinds your project — and your customer’s deposit to a halt.
Here’s what Canadian garages need to understand before bringing the next kit across the border in 2026.
The Classification Problem: One Kit, Many HS Codes
The first thing to understand about EV conversion kits is that the Canada Border Services Agency does not have a single tariff classification for “EV conversion kit.” What you receive at your shop’s loading dock — typically a crate or pallet containing a motor, controller, battery pack or modules, charger, DC-DC converter, wiring harness, mounting adapter plates, and various ancillary components — gets unbundled at the border into its constituent parts. Each component may fall under a different Harmonized System (HS) heading, attract a different MFN duty rate, and trigger different regulatory requirements.
The major classification buckets you’ll typically encounter include:
- Electric motors under HS heading 8501 (electric motors and generators). Sub-classifications depend on output power, typically falling between 8501.31, 8501.32, 8501.40, 8501.52, or 8501.53.
- Lithium-ion battery packs and modules under HS heading 8507.60.
- Motor controllers and inverters are typically under HS heading 8504 (electrical transformers, static converters, and inductors).
- Onboard chargers are also under HS 8504.
- Wiring harnesses and connectors under HS heading 8544.
- Mechanical adapter plates, mounting brackets, and driveline components are generally under HS 8708 (parts and accessories of motor vehicles), which carries a 6% MFN duty unless exempt under a free trade agreement.
Each of these classifications has its own duty treatment, and the difference between an MFN rate of 0%, 6%, and 8% across a $20,000–$45,000 kit becomes meaningful very quickly. There’s also a deeper risk: the CBSA has clear policy that if a shipment contains enough components to constitute a complete vehicle — or even something the agency considers a “kit car” — it may be reclassified entirely under HS heading 8703 or 8707, with very different duty and compliance implications. The CBSA’s Memorandum D10-14-45 on kit cars is the relevant reference, and it’s worth a careful read before structuring any large kit purchase.
For shop owners who’ve handled traditional restoration work, this is the single biggest change. You’re no longer in the simple “auto parts” universe. You’re in a hybrid classification space that draws from electrical machinery, batteries, vehicle parts, and — at the extreme — potentially complete vehicles.
The China Factor: A Surtax Story Still Being Written
A large share of EV conversion components — particularly batteries, controllers, and lower-cost motors — originate in China. That makes the country-of-origin question central to your landed cost calculation.
Here’s where things stand in 2026: Canada’s punitive 100% surtax on Chinese-origin finished electric vehicles was repealed effective March 1, 2026, replaced by a quota framework and the standard 6.1% Most-Favoured-Nation tariff. Eligible Chinese EVs now move under a shipment-specific permit system administered by Global Affairs Canada, with an initial annual cap of 49,000 vehicles. We’ve covered this framework in depth in our earlier piece on Canada’s Chinese EV quota and what it means for importers — and the same political logic that drove the EV quota deal is shaping how related goods are treated.
What’s important for the conversion kit market is that the surtax landscape for batteries, battery parts, and related components is a separate file and remains under active consideration. Canada launched a consultation on potential surtaxes covering batteries and battery parts, solar products, semiconductors, and critical mineral products in late 2024, and that file has not been fully resolved. Garages importing Chinese-origin lithium-ion cells, packs, or BMS (battery management system) components in 2026 should be tracking this closely — a surtax announcement on batteries could change the math on a $15,000 Chinese pack overnight.
Two practical takeaways for shop owners:
- Always confirm country of origin on every component in your kit, not just the kit as a whole. A kit “shipped from California” may contain a Chinese-built motor, a Korean cell pack, and Taiwanese electronics — each with its own origin and tariff treatment.
- Document origin meticulously. If the regulatory environment shifts and a remission order is later issued, the importers who claim refunds successfully are the ones who maintained clean origin documentation from day one.
CUSMA: Where U.S.-Sourced Kits Have an Edge
If your kit — or its individual components — qualifies as a good of U.S. or Mexican origin under the Canada-United States-Mexico Agreement (CUSMA), you may be able to claim preferential tariff treatment that reduces most duty rates to zero. For garages buying from established U.S. EV conversion specialists (and several major suppliers are operating out of California, Oregon, and Washington), this can be a significant cost advantage over Chinese sources even before adjusting for shipping and quality considerations.
The catch is that CUSMA preferential treatment requires the goods to actually qualify under the agreement’s rules of origin — not simply to ship from a U.S. address. The rules of origin for EV components, batteries, and auto parts are technical, and the regional value content calculations under CUSMA have specific thresholds. A motor that’s assembled in California but uses Chinese rare-earth magnets, Korean copper windings, and Mexican housings may or may not qualify, depending on how the math works out.
Your customs broker should be assessing CUSMA eligibility for each component, not just accepting the supplier’s certification at face value. CBSA verification audits on CUSMA claims have increased significantly, and a denied claim after the fact means paying back duties plus interest plus potential penalties.
Battery Imports: Where the Real Complexity Lives
Lithium-ion batteries are where EV conversion kit imports diverge most sharply from any other auto parts business you’ve done. The batteries are simultaneously:
- A tariff-classified good (HS 8507.60) with its own duty treatment
- A dangerous good (Class 9, UN 3480 or UN 3481) regulated under Canada’s Transportation of Dangerous Goods (TDG) Regulations
- A controlled good for transport packaging under standards including CGSB-43.146 and CSA B621
- An environmentally regulated good with end-of-life and cross-border movement implications under the Canadian Environmental Protection Act
For garages, the most immediate operational concern is the TDG layer. Lithium-ion battery packs from full EV applications typically require a “large means of containment” (greater than 450 litres in volume), and the off-the-shelf TDG containers built to CGSB-43.146 or CSA B621 standards are often not designed for EV packs. Importers may need to obtain a Transport Canada Equivalency Certificate to use a non-standardized container — a process that takes weeks and is not something you want to discover at the last minute.
Even where smaller modular packs are involved, you’ll be working with UN 3480 (lithium batteries shipped alone) or UN 3481 (lithium batteries packed with or contained in equipment) classifications, and your carrier needs proper documentation, labelling, and trained personnel. Air freight of larger battery packs is heavily restricted; ocean and ground freight are usually the practical options, both with their own packaging and documentation requirements.
This intersects directly with broader Canadian regulations on battery and clean-energy equipment imports. For shops that also handle solar, charging infrastructure, or energy storage system installs, many of the same compliance pathways apply — we’ve laid out the framework in detail in our guide to importing renewable energy equipment into Canada.
Transport Canada, CMVSS, and the “Is It Still the Same Car?” Question
Here’s a question every garage doing EV conversions eventually has to answer for a customer: once we’ve ripped out the engine, transmission, fuel system, and exhaust, and replaced it with a battery pack, motor, and electronic control system — is this still the same car under Canadian motor vehicle law?
The short answer is: usually, yes — but with important nuances.
Vehicles 15 years old or older are exempt from the federal Motor Vehicle Safety Act and the Canadian Motor Vehicle Safety Standards (CMVSS) at the point of import. This is the regulatory underpinning of the entire classic car import business, and we’ve covered it in detail in our guide to importing classic cars into Canada. For most EV conversion projects, the donor car is already in Canada and already registered, which sidesteps the CMVSS question at the federal level entirely. The conversion is a modification, not a new import.
But if you’re a garage that imports donor vehicles and kits — or that imports purpose-built EV-converted classics from U.S. shops — pay close attention to a few details:
- A vehicle being imported in pieces (chassis + body + drivetrain shipped together) may be classified as a vehicle, not as parts. The kit car memorandum becomes relevant.
- If you’re importing a U.S.-converted classic, the vehicle’s modifications may need to be documented for the Registrar of Imported Vehicles (RIV) program if under 15 years old (rare for genuine classics, but possible for newer “future classics”).
- Right-hand-drive vehicles, JDM imports, and vehicles with significant structural modifications may face additional provincial registration scrutiny regardless of federal status.
The Provincial Inspection Wall
This is where many garages get blindsided. Federal compliance — duties paid, CBSA released — does not get you a license plate. Provincial inspection and registration is a completely separate process, and the rules for converted vehicles vary widely.
In Ontario, the DriveON safety inspection regime applies to vehicles being registered for the first time in the province. There is no specific CMVSS-style standard for EV conversions; the inspector applies the standard Passenger/Light-Duty Vehicle Inspection Standard and uses professional judgment. In practice, this means a well-executed conversion with proper battery securing, fused high-voltage circuits, isolation monitoring, and OEM-quality wiring will typically pass without issue — but inspector discretion is real. Garages serious about this work should build a relationship with a Ministry-licensed inspection facility familiar with EV builds before they need one.
In British Columbia, vehicles imported from outside the province generally require inspection at a designated inspection facility. Conversions, custom builds, and vehicles with significant modifications are explicitly outside the New West Partnership exemption that covers simple inter-provincial moves.
In Quebec, a safety inspection is mandatory for any vehicle being registered in the province for the first time, which includes vehicles undergoing major modifications.
In the Atlantic provinces and the territories, requirements vary by jurisdiction and inspector discretion plays a larger role.
The practical implication: confirm provincial requirements before taking the customer deposit, not after the conversion is complete. A conversion that can’t pass provincial inspection is a six-figure problem.
Insurance and Registration: The Quiet Compliance Layer
EV conversions create insurance complexity that often surprises both shops and customers. Many mainstream insurers will not write policies on converted vehicles, classifying them as modified or non-standard risks. Specialist insurers — TD Meloche Monnex has historically been willing to insure EV conversions in Ontario, often subject to inspection by an EV specialist — fill some of this gap, but coverage availability varies by province and the specifics of the conversion.
For garages, this matters because customers will ask you the insurance question, and the answer affects whether your project even makes economic sense for them. Building a referral relationship with insurers and specialist appraisers familiar with EV conversion valuations is worth the upfront effort.
Best Practices for Canadian Garages Scaling EV Conversion Work
Pulling all of this together, the garages that successfully scale EV conversion services in 2026 are doing several things consistently:
Engage a customs broker before placing your first major kit order. Not after the shipment is in transit. Not at the border. Before. The classification, origin, and TDG documentation work done upfront determines whether the project lands cleanly or sits in a CBSA examination warehouse for two weeks.
Build a multi-source supplier pipeline. Relying entirely on Chinese-origin components exposes you to surtax risk. Relying entirely on U.S. CUSMA-eligible sources exposes you to CUSMA verification risk. A mixed sourcing strategy with documented origin for every component creates the most resilient cost structure.
Document, document, document. Country-of-origin certifications, CUSMA certifications of origin, TDG shipping documents, battery test summaries (UN 38.3 reports), and CBSA accounting documents should all live in a project file you can produce on demand. CBSA verifications can come 12, 24, or even 48 months after the fact.
Pre-clear provincial inspection requirements with the customer. Get them to acknowledge in writing that the conversion will require provincial inspection and that inspection outcomes are not guaranteed.
Track the regulatory file actively. The 2026 Chinese EV quota framework is unlikely to be the last major change. Battery-specific surtaxes, CUSMA Joint Review outcomes, and provincial inspection rule updates are all live files that can change your unit economics.
The Bottom Line
EV conversion of classic cars sits at the intersection of two of the most regulated areas of Canadian trade: automotive imports and battery/clean-energy equipment imports. For garages, that complexity is both the barrier and the opportunity — shops that build genuine compliance competence will be able to take on higher-value work that competitors can’t touch.
The economics of a well-managed EV conversion business are strong. But “well-managed” in 2026 means treating import compliance as a core operational function, not an afterthought handled by whoever happens to be at the receiving dock when the freight arrives.
If you’re scaling EV conversion services and want to put your import workflow on a professional footing, Clearit Canada works with automotive shops and specialty importers across the country to handle the customs classification, CUSMA eligibility, TDG documentation, and CARM compliance side of the equation — so your team can focus on building cars instead of fighting paperwork.
