What the corporation actually protects
A garage holds other people's vehicles, sends techs on road tests and works under hoisted cars, so the first line of defence is a proper garage insurance policy, not a corporate seal. What incorporation adds is the second line: when the shop operates as a corporation, the lease tail, supplier balances and any claim beyond policy limits stop short of the owner's house and savings. That wall only holds where you have not signed it away, and landlords and equipment lenders will ask for personal guarantees, so part of the job is keeping those narrow and dated.
The tax case runs alongside. Profit retained in the corporation is taxed at roughly 12.2% on the first $500,000 in Ontario, against personal rates that can run four times that at the top, which turns retained earnings into the fund that buys the next hoist or the next bay. And if the shop is ever sold as shares of a qualifying small business corporation, up to $1.25 million of gain per shareholder can be sheltered by the lifetime capital gains exemption, an exit a sole proprietorship simply does not have.
The paper that must move with the business
A repair shop is licensed, leased and account-bound, so the switch to a corporation is a sequencing project, not a signature. We plan the change date around the pieces below so nothing stops mid-week.
| Item | What happens at incorporation |
|---|---|
| Premises lease | Assigned to the corporation only with landlord consent; expect a personal guarantee request and negotiate its limits |
| MVIS licence | Issued to the operator, so the corporation needs its own; arrange it with the Ministry of Transportation before the switch so safety inspections never pause |
| HST account | Does not transfer; the corporation registers fresh and the sole-proprietor account closes with a final return |
| WSIB | A new account for the new employer, with the old one closed off cleanly |
| Payroll | New business number and program account; staff get two T4s for the changeover year |
| Jobber and warranty-plan agreements | Re-signed in the corporate name so parts terms and claim payments do not bounce |
Moving the assets in without a tax bill
The hoists, tools, parts stock and goodwill do not have to be sold to the corporation at a gain. A section 85 rollover transfers them at elected amounts that defer the tax, papered with its own CRA election form and a price adjustment clause. On the HST side, a joint section 167 election on form GST44 lets the corporation take over substantially all the assets of the business with no HST on the transfer; without it, the new company pays 13% to its own predecessor and waits a filing period to recover it, a cash hole with no purpose. The corporation should also register for HST from day one, because a going concern is past the $30,000 small-supplier threshold before its first month closes.
Timing matters here too. We usually put the switch at the start of an HST period and a payroll month, so the final sole-proprietor return covers a clean stretch and the T4 split lands on a tidy date. Rushed incorporations that straddle a quarter create reconciliation work that outlives the savings.
Family shares are a day-one decision
Share structure is cheap to design at incorporation and expensive to fix later. Dividends to family members get taxed at top rates under TOSI unless an exclusion applies, and a garage has two realistic ones. A spouse who genuinely works in the business an average of 20 hours a week, on the counter, the books or the phones, can fit the excluded business rule. And excluded shares, which require 10% of votes and value, also require that less than 90% of the corporation's business income come from services; a shop with a real parts and tire counter can land on the right side of that line, which most service businesses cannot, so it is worth testing against your actual sales mix.
We set the classes accordingly: separate share classes where dividend flexibility is wanted, and room left for the exemption at a future sale. Walla Assaf's corporate structuring background does the design, and our Incorporation service files the articles, registers every account and papers the rollover as one engagement, quoted in writing after a free 15-minute discovery call. If the shop incorporated years ago and the shares are wrong, Corporate Restructuring repairs them. The owner-pay decisions that follow the switch live on our tax planning page, and we run this playbook for garages across Mississauga and the GTA.
