The test is retained profit, not revenue
A sole proprietor pays personal marginal rates on every dollar of profit, needed or not. A corporation pays roughly 12.2% combined in Ontario on the first $500,000 of active income, and the difference is deferred rather than erased: it comes due when you pay yourself. So the real question is not how big the revenue is; it is how much profit stays in the business.
Landscaping companies retain for a concrete reason: iron. If next season needs a second truck and a salter, funding them from profit taxed at 12.2% instead of your personal rate is the whole case in one sentence. If every dollar leaves the company to pay the household bills, the deferral mostly evaporates and incorporation is overhead.
Two quieter benefits suit a seasonal trade. A corporation can pay you a level salary through a heavy winter and a dry one alike, absorbing the swings on its own books instead of your T1, which steadies both the household and the mortgage application. And if the company one day sells, a maintenance book with commercial contracts attached is a saleable asset, and a share sale can reach the lifetime capital gains exemption, now $1.25 million, provided the corporation is kept clean along the way.
Snow raises the stakes
Snow and ice work carries real injury exposure. Since 2021, Ontario law requires written notice of a slip-and-fall claim arising from snow or ice within 60 days, served on the occupier or the snow contractor, a rule created precisely because these claims are common. Insurance is the first line of defence and incorporation replaces none of it, but a corporation keeps a contract dispute or an uninsured gap away from your house and personal savings.
Commercial bids push in the same direction. Property managers routinely require a corporate contractor, certificates of insurance and a WSIB clearance before a truck touches the lot. For a company chasing plaza and condo contracts across the GTA, the structure is often a bidding requirement before it is ever a tax strategy.
What changes the day after
| Question | Sole proprietor | Corporation |
|---|---|---|
| Tax on profit | Personal marginal rates on all of it | About 12.2% on the first $500,000 of active income |
| Year-end | December 31, mid snow season | Chosen at setup; we usually place it between seasons |
| Paying yourself | Draws, no slips | Salary, dividends or a mix, planned each year |
| Filings | T1 with self-employment schedules | T2 return, T4 and T5 slips, corporate records |
| HST and WSIB | Registered to you personally | New accounts in the corporation's name |
The last row is the one people miss. The corporation is a new legal person: new business number, new HST registration, WSIB set up again, snow contracts re-signed and insurance re-papered in the corporate name. We run that checklist inside every Incorporation engagement so nothing bills under the wrong name when the season opens.
Moving the fleet in without a tax bill
Trucks, trailers and equipment do not have to be sold to the new corporation at a taxable gain. A section 85 rollover transfers business assets at an elected amount and defers the tax, and a joint HST election normally keeps the transfer of the business's assets free of HST as well. Financed equipment needs lender consent before it moves, a phone call best made before incorporation day rather than after. Done in the right order, the company starts its first season owning its fleet with nothing triggered on the way in.
Timing helps too. Incorporating in the quiet weeks between the last salt run and the spring ramp means the corporation's first year opens clean, with contracts, payroll and HST all starting under one name instead of switching mid-season.
When staying simple wins
A solo operator mowing thirty lawns, sitting under the $30,000 small-supplier line and drawing everything the business makes, gains little from a corporation and takes on a T2, a minute book and higher accounting costs. Staying a sole proprietor with clean records and CPA Quick Support at $99 a month is often the better year. The switch point is measurable: retained profit, commercial contracts, first hires. We would rather tell you to wait than sell you a structure, and the numbers get run in a free 15-minute discovery call.
