How to Start a Mobile Car Detailing Business in Canada

Why mobile detailing works as a first business

The customer never has to leave the house, the shop never has a lease, and the skill is learnable in a season. Canadians already pay for convenience on wheels, from dog grooming to oil changes, and a car detail is the same convenience pitch applied to the driveway.

The trap is the same as the appeal. Anyone can buy a vacuum and a hose, so the operators who last are the ones that get the unglamorous parts right early: the wastewater rule most newcomers never hear about, insurance before the first commercial client asks for it, a rig that actually works in a customer's driveway, and before-and-after photos that sell the next job.

This guide walks through a solo mobile start as a sole proprietor. That is how most operators begin. Incorporation can wait until the income and the risk justify the extra paperwork. If you are unsure which structure fits your plans, our 5-question quiz walks through the choice.

Step 1: Pick one service lane to sell first

Do not launch with "we detail everything." Each lane has a different buyer, a different rig requirement, and a different price.

• Residential driveway details serve homeowners. You need the full mobile rig with water and power, the buyer is easy to reach, and before-and-after photos sell the job.
• Fleet and commercial work serves delivery companies, contractors, and dealerships. The buyer signs recurring contracts, always asks for insurance first, and expects written quotes and receipts.
• Premium interior and paint services cover paint decontamination, polishing, headlight restoration, and odour removal. These need more skill and tools, command the highest prices, and work through winter in a heated garage.

Start with residential. The buyer is easiest to find, the rig is the standard one, and you learn pricing on jobs where a mistake costs you an afternoon, not a contract.

Step 2: Register the business name in your province

Detailing is not a regulated trade, so there is no trade licence to worry about. This step is paperwork, not qualification.

If you operate under your own personal name, most provinces let you start without registering a name. If you trade as anything else, say "Maple Shine Detailing," you register the business name with the province: about $60 through the Ontario Business Registry (good for five years) or $30 for a name request plus $40 to register in BC. A CRA business number is free, and you need one when you register for GST/HST or payroll.

Step 3: Build the mobile rig

The rig is the business. It has to bring its own water, its own power, and everything you need to do a full job without the customer's garden hose or outlet.

• A 50 to 100 gallon water tank with a 12-volt pump is the standard operator recommendation. Secure it with ratchet straps and anchor points: water is heavy, and a shifting tank on a trailer or in a van is a safety problem.
• A generator or inverter sized to run your pressure washer, vacuum, and polisher together. Operator guidance generally lands around 4,000 to 6,500 watts for a full electric rig, though an inverter-only setup works for lighter loads.
• A pressure washer around 1,500 to 2,000 PSI with a foam cannon. That is strong enough to clean and gentle enough for paint; more pressure gouges clear coat, not dirt.
• A wet/dry vacuum or hot-water extractor for interiors, microfibre towels (dozens of them), brushes, applicators, and a chemical starter kit: pH-balanced car shampoo, all-purpose cleaner, glass cleaner, interior dressing, tyre gel, and spray sealant.

Two buying rules. First, buy reliable mid-range professional equipment, not the cheapest option: cheap tools break faster and produce lower-quality finishes, and a failed pump mid-job costs you the booking and the review. Second, build the rig to your lane: a residential driveway rig and a fleet rig have different tanks, pumps, and containment needs. Upgrade with revenue, not debt.

Step 4: Learn the wastewater rules before your first job

This is the step that separates a real operator from a hobbyist with a hose.

Wash water from a driveway detail carries dirt, brake dust, oil, metals, and chemicals. Cities regulate it. Calgary's compliance materials for mobile wash operators state that discharging wash water to the stormwater system is prohibited, with penalties under the wastewater bylaw — fines for discharging a prohibited substance begin at $1,000 — and the compliant options are collecting all wash water and disposing of it at an approved facility or discharging it to the wastewater (sanitary) system where the bylaw allows it. Most Canadian municipalities have equivalent stormwater prohibitions.

Practical implications for your rig: use biodegradable, low-phosphate products; keep wash water off driveways that drain to the street; consider a wash mat or berm for containment on commercial jobs; and read your own city's wastewater or stormwater bylaw page before the first job. A bylaw officer's visit is the most expensive free lesson in this business.

Step 5: Sort insurance before you move a customer's car

Residential clients rarely ask. Commercial clients always do. And you are in a unique position among trades: you routinely drive and park other people's vehicles.

A broker who insures contractors can quote commercial general liability. Ask them specifically about coverage while a customer's vehicle is in your care, being driven, or stored on your trailer or in your van, because that is the exposure standard CGL policies may treat specially. Being able to attach a certificate of insurance to a quote is often what separates you from the operator with no paperwork, and fleet managers will not onboard you without it.

Step 6: Plan for winter in October

Winter is the predictable shock, so plan for it in the first season, not the second.

Exterior work runs roughly spring through fall in most of the country. The operators who keep earning through winter sell interior-only services that work in a heated garage: full interior details, odour removal, headlight restoration, leather conditioning. Others chase fleet and dealership contracts that run twelve months, or use winter for equipment maintenance, marketing, and booking the spring rush.

The spring surge is real: winter road salt and grime create a predictable April backlog of cars that all need the same interior-exterior reset. Market in March, not May.

Step 7: Get the first jobs

No registry hands you work. What works is the same unglamorous playbook as every local service.

• Before-and-after photos. This is the whole marketing department. A driveway detail is the most photogenic service business there is. Take them on every job, with permission, and put them on a free Google Business Profile before you spend a dollar on ads.
• One platform profile. A Google Business Profile with real photos and real reviews does more than a website nobody finds.
• The first five. Friends, family, and neighbours at an honest price. The first five clients are the hard ones; after that, referrals compound, which is exactly why you keep your early work excellent and your invoicing boringly reliable.
• Dealerships and fleets later. Used-car lots, delivery companies, and trade contractors buy recurring detailing work, but they buy from operators with insurance, written quotes, and references. Work your way up to them.

Startup checklist

• Tank secured with straps and anchor points; rig tested in a driveway before the first paid job
• Commercial general liability quoted by a broker before the first commercial or fleet job
• Municipal business licence checked; city's wastewater/stormwater bylaw checked
• Revenue tracked against the $30,000 GST/HST rolling threshold
