How to Start a Mobile Mechanic Business in Ontario
Start a mobile mechanic business in Ontario: the compulsory 310S trade certificate, the $60 business name registration, municipal licences, insurance, safety certificates, and HST.
Start a fixed auto repair shop in Canada: pick the bays and services first, sort trade certification and municipal licensing for the exact shop, and set up parts, waste, and inspection work before opening.
Applies in: across Canada
A fixed auto repair shop is a bays-and-people business. The lift count, the services you offer, and the technicians you can staff decide what you earn. The paperwork decides whether you can open at all: trade certification rules in your province, zoning and any municipal licence for the exact shop, and a lease that lasts long enough to pay back the fit-out. Sort those three before you buy a lift. A shop with certified staff, a legal premises, and a steady booking book can grow. A shop with good tools in the wrong premises, or with no certified staff in a compulsory province, cannot.
Do not lease a shop and then decide what it does. Write the service list first:
Each service sets the bay count and the equipment. A two-bay general shop with one lift per bay is a different build from a tire shop that needs storage for hundreds of customer tires each season. Count the cars you need per bay per day to cover rent, wages, and parts, and check that count against the traffic and the competing shops on the same road. A shop that needs eight cars a day in a location that sees three is a lease problem, not a marketing problem.
This is the licensing-heavy part of the guide, and it is not legal advice: your provincial apprenticeship authority is the source for your province, and its answer governs.
The federal Job Bank states that trade certification for automotive service technicians is compulsory in Nova Scotia, Prince Edward Island, New Brunswick, Ontario, and Alberta, and voluntary in Newfoundland and Labrador, Quebec, Manitoba, Saskatchewan, British Columbia, the Yukon, the Northwest Territories, and Nunavut. The usual route is a four-year automotive service technician apprenticeship program, or a combination of over four years of work experience and industry courses in automotive technology. A Red Seal endorsement is available to qualified technicians who pass the interprovincial Red Seal examination.
In a compulsory province, plan hiring around certification from day one. An apprentice can work under a certified technician, but the shop cannot present uncertified staff as certified, and it cannot do restricted work without the right people. In a voluntary province, certification still matters for hiring and for customer trust, and for warranty or dealer-adjacent work that asks for it. Either way, put the certificate question in every job ad and every interview, and keep copies on file.
No province issues a general repair shop operator licence, but cities regulate the use, and the shape varies. Windsor is the worked example of a direct licence: a building or place used as a motor vehicle repair shop is licensed as an automobile service station, at $397 new and $315 for a renewal for repairs, with a business ownership declaration, identification, incorporation or master business licence documents where they apply, and a police records check for new repairs applications. The licence renewal deadline in Windsor is October 31.
Other cities take the zoning route instead, with no repair-specific licence, and the permission comes through zoning, a development permit, and a building permit for the fit-out. Whatever your city, get two answers in writing for the exact address: does the city licence motor vehicle repair shops, and does the zoning allow a repair shop on this parcel? Also ask about outdoor storage, customer parking, signage, hours, and noise, because a shop that stores customer cars outside or runs compressors late draws the complaints that bring inspectors. A lease signed before those answers arrive is a gamble, not a plan.
Register the business name in the province where the shop sits: $60 for five years in Ontario, $40 plus a $30 name request in British Columbia, with other provinces in the same range. Get a Canada Revenue Agency business number, which is free, and register for GST/HST when you pass the $30,000 threshold, or voluntarily before it so you can claim input tax credits on tools, equipment, and parts. If you operate in Quebec, you also deal with QST.
Insurance is not optional in practice. Liability coverage for injuries on the premises, garage coverage for customer vehicles in your care, and property coverage for lifts, tools, and parts are the baseline, and a leased shop will usually require the landlord to be named on the policy. Tell the insurer the shop is a public repair operation with customer vehicles on site, not a private garage, or the claim you need most will be the one the policy does not cover. If you hire staff, workers compensation registration in your province comes with the first hire, not after the first injury.
Buy lifts, diagnostics, and compressors to the service list, not to a catalogue. A lift that cannot take the heaviest vehicle you plan to service is wasted money, and a scan tool without current software is a paperweight. Set up parts storage with labelled bins, a clean area for customer parts, and a secure area for keys and customer vehicles. Arrange disposal routes before opening for used oil, oil filters, solvents, tires, batteries, and scrap metal, and keep the pickup records: waste handlers, landlords, and insurers all ask for them, and a shop that stockpiles waste oil in drums behind the building is asking for a visit.
Set the job routine before the first customer: intake inspection with photos, a written estimate before work starts, a call before any extra work, and the old parts kept for the customer. That routine is what keeps disputes small and repeat customers coming back.
Inspection work is a separate decision. In Ontario, DriveON replaced the paper-based Motor Vehicle Inspection Stations program on March 31, 2025, and DriveON facilities and technicians are the only ones allowed to conduct the inspections the program covers. Applying needs a business number, tax compliance verification, business registration or incorporation documents, banking information, and a business insurance certificate. Other provinces run their own inspection programs with their own rules, so check yours rather than assuming Ontario's program applies.
Open with a booking system that fits the shop: phone and online booking, a daily bay plan, and a parts ordering cutoff so morning jobs are not waiting on afternoon deliveries. Price from the service manual time and the parts quote for the exact vehicle, not from a neighbouring shop's sign. A shop that books honestly, photographs faults, and calls before extra work earns the repeat oil changes and brake jobs that pay the rent between the big repairs.

Licence fees are Windsor's published figures, not a national price list — your city's fees and licence categories differ, and some cities do not licence repair shops directly. Lifts, diagnostics, tools, and the lease dwarf every fee on this table; price those from quotes for your shop.
It depends on the province, and on who does the work. The federal Job Bank states that trade certification for automotive service technicians is compulsory in Nova Scotia, Prince Edward Island, New Brunswick, Ontario, and Alberta, and voluntary in Newfoundland and Labrador, Quebec, Manitoba, Saskatchewan, British Columbia, the Yukon, the Northwest Territories, and Nunavut. The usual route to certification is a four-year automotive service technician apprenticeship program, or a combination of over four years of work experience and industry courses. An owner who does not hold the certificate can still run a shop in a compulsory province, but the repair work itself must be done by, or under, people who meet the provincial rule. Check your provincial apprenticeship authority before you hire, and do not assume a certificate from one province answers the question in another.
A fixed shop sells bays, lifts, and equipment a van cannot carry, and it takes on the lease, zoning, and waste handling that come with a premises. A mobile mechanic sells convenience and low overhead, and is limited to work that fits in a van and can be done safely at a customer's location. The fixed shop suits heavy work, diagnostics that need shop equipment, tires, and inspections. The mobile model suits light repair, maintenance, and roadside-style jobs. Many owners start mobile to build a customer base, then open a shop once repeat work outgrows the van. The two models share the trade certification rules, but only the fixed shop faces the municipal zoning, signage, and premises licence questions in this guide.
There is no national repair shop licence, and the municipal layer varies city by city. Some cities licence the use directly: Windsor licences a building or place used as a motor vehicle repair shop as an automobile service station, at $397 for a new repairs licence and $315 for a renewal, with application requirements that include a business ownership declaration, identification, incorporation or master business licence documents where they apply, and a police records check for new repairs applications. Other cities regulate repair shops through zoning and building permits only. Ask your city two questions for the exact address: does it licence motor vehicle repair shops, and does the zoning allow a repair shop on this parcel? Get both answers in writing before you sign a lease or buy equipment.
Only if it joins the DriveON program. Ontario's DriveON program is the digital-based program for vehicle safety and emissions inspections, and it replaced the old paper-based Motor Vehicle Inspection Stations program, which ended on March 31, 2025. DriveON facilities and technicians are the only ones allowed to conduct the inspections the program covers, including safety inspections for passenger vehicles and emissions tests for heavy-duty diesel commercial vehicles. Applying involves a business number, tax compliance verification, business registration or incorporation documents, banking information, and a business insurance certificate. Inspection work is an add-on to a repair shop, not a default part of opening one, and the equipment and technician requirements are separate from general repair.
Once your taxable supplies pass $30,000 over four consecutive calendar quarters, or $30,000 in a single calendar quarter, you must register for GST/HST and charge it on your repair services and parts. Registration is free through the Canada Revenue Agency, and you have 29 days from the day you pass the threshold to register. Many shops register voluntarily before the threshold so they can claim input tax credits on tools, equipment, parts, and rent. If you operate in Quebec, you also deal with QST. Keep parts, labour, and tax on separate lines on every invoice from the start: repair customers dispute invoices, and a clean invoice is what settles those disputes.
The lease first: a shop signed on a busy road with the wrong zoning, or with a short term on a space you just fitted with lifts, is hard to fix after the fact. Hiring second: in compulsory-certification provinces, a shop that cannot staff certified technicians cannot legally do the work it advertises, and good technicians are hired on reputation and pay, not on job ads alone. Waste and safety third: used oil, filters, solvents, tires, and batteries must go to lawful disposal routes, and a shop floor with poor ventilation, unguarded lifts, or no spill routine draws inspectors and insurers alike. And comebacks fourth: a repair that returns twice costs the parts, the bay time, and the customer. Price jobs from the service manual and the parts quote, photograph the fault before you start, and keep the old parts until the customer collects the car.
