What a sole proprietorship makes you carry
A collision shop stores other people's vehicles overnight, many worth more than the shop could absorb losing, beside solvents, ignitable waste and a booth engineered around fire risk. Insurance answers first: garage liability with garagekeepers coverage for the cars in your care. Incorporation is the wall behind the policy. Operated as a corporation, the five-year lease tail, the paint jobber's account and any claim that outruns coverage belong to the company rather than to the family balance sheet. That matters in this trade more than most, because one spreading fire, one stored vehicle stolen off the lot or one disputed repair on a six-figure EV can produce a claim no reasonable premium fully covers. The wall only stands where personal guarantees have not been signed over it, so part of our job is keeping those few, capped and reviewed as the corporation earns its own credit.
| Question | Sole proprietor | Corporation |
|---|---|---|
| A claim beyond policy limits | Reaches personal assets | Stops at the company, absent guarantees |
| Profit kept to fund equipment | Taxed at your personal marginal rate | Roughly 12.2% on the first $500,000 |
| Selling the shop one day | Asset sale only | Share sale possible, with up to $1.25 million per shareholder under the lifetime capital gains exemption |
| Paying family | Market-rate wages only | Wages plus dividend classes, governed by TOSI |
The environmental file belongs to the operator, and the operator is changing
Refinishing in Ontario runs on registrations that attach to whoever carries on the activity, so a new corporation cannot borrow the ones in your name. Automotive refinishing registers in the province's Environmental Activity and Sector Registry, and the corporation needs its own registration before the booth sprays a panel under the new name. Waste paint, solvent and thinner make the shop a registered hazardous waste generator, so that registration is redone too, and the waste hauler's manifests start quoting the new one. Municipal shop licensing, where your city requires it, follows the same person-specific logic.
The commercial paper moves in parallel: WSIB opens an account for the new employer, HST and payroll run under a fresh business number, garagekeepers coverage is re-issued naming the corporation, and every DRP agreement is re-signed so insurer payments land in the right bank account instead of bouncing between names. None of it is hard; all of it has lead time, so we build the switch date backwards from the slowest item on the list.
The lease is the hardest negotiation in the file
The booth is bolted into a building you do not own, which hands the landlord leverage twice. Assigning the lease to the corporation needs consent, and a collision tenancy invites clauses worth reading slowly: environmental provisions that make the tenant answer for contamination, make-good obligations at end of term, and the question of who owns the booth, ducting and compressor lines when the tenancy ends. We negotiate the assignment with those clauses in view, record the property's condition at the changeover so historic contamination stays historic, and keep any fresh personal guarantee capped, dated and shrinking. The term itself is a tax input too, since the Class 13 write-off on the booth install follows the lease length, so renewal options get read with the accountant's hat on as well as the tenant's.
Shares for the family, and assets moved without a tax bill
Share design costs little on day one and a restructuring later, so it happens at incorporation. Where a spouse genuinely works the office or family will hold shares, we set separate classes with TOSI in view; a shop with real parts content in its sales mix has more room under the exclusions than a pure service business, and we test yours before anyone counts on a dividend. The frame machine, tools, stock and goodwill roll into the corporation at elected values under a section 85 election, with a joint GST44 election keeping 13% off the transfer itself, so the move costs paperwork rather than tax.
Our Incorporation service runs the sequence end to end, articles, registrations, elections and share classes, designed with Walla Assaf's corporate structuring background behind it. Shops that incorporated years ago on a template get repaired through Corporate Restructuring. What you pay yourself after the switch is decided on our tax planning page, and the work starts with a free 15-minute discovery call and a written quote, for collision shops across Mississauga and the GTA.
