The short answer: two to three years, because two clocks are already running
Start preparing the moment a sale becomes realistic within five years, and treat two full years as the point past which options start closing. Two separate clocks set that timeline, and neither can be wound back later.
The first is the tax clock. The 1.25 million dollar lifetime capital gains exemption, usually the single largest tax saving available on the sale of a Canadian business, only applies to shares that pass a set of tests, and two of those tests measure the past: the shares must have been held by you or people related to you for the 24 months before the sale, and through that whole 24 months more than half the corporation's assets must have been used in the active business. A corporation carrying surplus cash or investments, or shares recently moved to a spouse or family trust, can fail tests that no year-end manoeuvre can fix, because the test is about what already happened.
The second is the record clock. A buyer prices the business on its demonstrated, normalized earnings, usually the last three completed years plus the current one, and on financial statements their accountant can verify. Margins you improve this year only show up as a trend once two more year-ends confirm them. So the real question is not how long the sale process takes, which is often six to twelve months on its own, but how many clean years of structure and results you want on the table when it starts.
| How far out | What should be finished | Why it cannot be compressed |
|---|---|---|
| Three or more years | Ownership and structure settled: exemption status checked, purification underway, succession direction chosen | Holding periods and the 24-month asset test cannot be backdated |
| Two years | Passive assets onside and staying onside; personal spending out of the company; margins where you want them judged | The asset test measures every month from here to closing, and buyers price trends, not promises |
| One year | Statements at the right assurance level, add-back schedule documented, valuation expectations set, data room started | Diligence rewards records that already exist, not explanations |
| Ninety days | Filings current, balances paid, contracts and minute book complete | Every loose end found in diligence becomes a price cut or a holdback |
Three or more years out: settle the structure and the direction
The earliest work is structural, because it is the slowest to take effect. Have the exemption status of your shares tested against the corporation's actual balance sheet: if surplus cash, a portfolio or a rental property has accumulated inside the company, the cleanup, called purification, has to start early enough for the 24-month test to be met, and the mechanics are covered in what corporate purification is and when you need it. If a holding company, family trust or estate freeze belongs in the picture, whether to multiply exemptions across family members or to separate sale proceeds from the operating company, it needs to exist and hold shares well before the sale, not during it.
This is also when the succession direction should be chosen, because it changes the entire plan. A third-party sale optimizes for price and a clean exit. A transition to your children optimizes for the business surviving the handover and for how the family finances your exit, often over years rather than at a single closing. A sale to managers usually depends on outside financing and vendor patience. Each direction implies a different structure, a different timeline and different tax planning, and switching directions late costs time you no longer have.
Two years out: build the earnings record a buyer will pay for
From two years out, the priority shifts from structure to results, because you are now living inside the window a buyer will scrutinize. Get personal and discretionary spending out of the company, or at least cleanly identified, so the eventual add-back schedule is short and provable; a normalization schedule full of arguable items invites a buyer to discount everything, and the discipline behind a credible one is set out in how to normalize earnings before selling a business. Put your own compensation on a defensible footing, formalize the handshake arrangements with key customers and suppliers, and reduce the business's dependence on you personally, because owner dependence is one of the few problems that takes years, not months, to fix.
This is also the point to decide what level of financial statements the sale will need. Compiled statements that were fine for the bank may not carry a multi-million dollar deal, and moving up to review-level assurance is far more persuasive with two years of history than with one, as covered in how to prepare financial statements for a business sale.
The final year: valuation, the route, and the buyer's financing
The last year before going to market is about converting preparation into a deal. Set your valuation expectations against normalized earnings and current market multiples rather than hope, so you can recognize a good offer when it comes. Settle, with advice, which sale route you will push for, because whether you sell the company's shares or its assets changes your tax bill, the buyer's position and the negotiation itself; the trade-offs are mapped in should you sell shares or assets. Assemble the data room while nobody is waiting on it: statements, tax filings, contracts, leases, the minute book.
Think about the buyer's side of the closing table too. Most purchasers of businesses in this size range borrow to buy, and their lender will underwrite your statements as carefully as the buyer does, so a business whose records support financing is worth more and closes faster. We sit on the financing side of these files regularly through our business financing support, and the difference between a fundable file and a messy one shows up directly in what buyers can offer.
Selling sooner than you planned: what ninety days can still do
An unsolicited offer or a change in health can collapse the timeline, and ninety days of triage still matters. Bring every filing current and clear any CRA balances, because arrears found in diligence become holdbacks. Build the add-back schedule now, with documentation for the strongest items and honesty about the weak ones. Have the exemption tests checked immediately: if the shares qualify today, plan the sale so nothing breaks that before closing; if they do not, the deal structure may need to change, and knowing that before negotiations is worth real money. Accept what cannot be fixed in the window, and concentrate on the items a buyer will actually price.
What changes your timeline, and how we run the runway
Where you personally fall between ninety days and five years turns on a short list of facts:
- Whether your shares pass the exemption tests today. Clean shares shorten the runway by a year or more; an offside balance sheet sets a two-year floor on its own.
- How much of your life runs through the company. Heavy personal spending in the books needs clean years behind it before a buyer will believe the normalized number.
- Who the buyer will be. Family and management transitions need longer than third-party sales, because financing your exit takes years of structure, not a closing day.
- How dependent the business is on you. If you are the business, the runway is however long it takes to make that untrue.
- The state of your statements and filings. A business already producing review-quality statements on time can move fast; one running on a shoebox cannot.
We work these runways as a CPA firm for owners buying, selling or transitioning businesses across Ontario: the structural work, purification and reorganizations as defined-scope engagements under Strategic Projects, and the multi-year record-building as part of an ongoing engagement. The full pre-sale checklist lives in preparing a business for sale in Canada, and a free 15-minute discovery call is enough to tell you which clock you are actually up against.
