The obligations are the argument
A renovator's risk is not abstract. It is a supply failure that stalls a gutted kitchen for a month, a shower pan that leaks into the ceiling below a year after the final draw, a cancelled project where the client wants the deposit back and disputes what was complete. As a sole proprietor, each of those claims runs against you, the same person who owns your house and your savings. A corporation signs the contracts, holds the deposits and carries the warranty, so claims reach corporate assets first.
The honest boundaries: your own negligent work is still yours, personal guarantees you sign for the bank or a supplier survive incorporation, and insurance remains the first answer to site damage, the corporation the second. Money received on a project also stays trust money for the trades and suppliers who worked on it under Ontario's Construction Act, and directors who ignore that answer for it personally, incorporated or not. The structure is real protection, not immunity, and we say exactly that at the discovery call, not after the invoice.
What the 12.2% rate builds
An unincorporated renovator pays personal rates on every dollar of profit, above 53% at the top in Ontario, whether the money was spent on living or left in the business. A corporation pays about 12.2% on the first $500,000 of active profit, and the difference stays working: it funds the next display kitchen, the cabinet-shop deposits that long lead times demand, another wrapped van, the showroom lease, all in dollars that have only met the small-business rate. The corporation wins in proportion to what you can leave inside it; an owner drawing every dollar to live on gains far less, and deserves to hear that before paying for articles. Years from now, a sale of shares rather than assets can shelter up to $1.25 million per shareholder under the lifetime capital gains exemption, which is a reason to grow the business inside a corporation from early on.
What moves with you on day one
Incorporating a running renovation firm is a transfer, not just a filing, and each piece has its own rules:
| Piece | What changes |
|---|---|
| Client contracts and deposits | New agreements in the corporate name; never switch entities mid-project, time the change to a gap between jobs |
| WSIB | Construction work carries compulsory coverage, so the corporation registers its own account; one executive officer who performs no construction work can apply for the exemption |
| HST | The corporation registers fresh; deposits taken and invoices issued before the switch belong to the old registration |
| Insurance | Commercial general liability and any installation coverage reissued in the corporate name, client certificates updated |
| The brand | A numbered company can carry your trade name registered under the Business Names Act, so the Houzz profile, the reviews and the truck wraps stay exactly as they are |
Our Incorporation service runs that sequence end to end, with articles and a share structure designed for a future holding company rather than rebuilt for one later, and pairs it with a first-year owner-pay plan through Tax Planning and Advisory. Commitments still ahead of you are simpler than transfers: if the showroom lease, the cabinet-line dealer agreement or the first fleet loan has not been signed yet, incorporating first puts each of them in the corporation's name from day one, with no assignment clauses to negotiate later.
The line where renovating becomes building
Renovating an existing home does not require a builder licence. Tear a house down to the foundation and rebuild it, or take on new-home work for a client, and you have crossed into territory where an HCRA licence and Tarion warranty enrolment are mandatory, and the licensee is the entity, not the person. If a teardown-rebuild is anywhere in your plans, the corporation should exist and hold the licence before that contract is signed, because rebuilding your structure around a live licence is far harder than sequencing it correctly the first time.
The same logic covers the quieter transitions: bringing a designer in as a minority shareholder, splitting the showroom lease from the operating risk, or setting up for the day a cabinet line becomes its own business. Share structure decided at incorporation is cheap; the same decisions made later run through lawyers and rollovers. We incorporate renovation firms across Mississauga and the GTA, quoted in writing after a free 15-minute call.
