Finding a promising business can create real momentum. The revenue looks attractive, the owner has a convincing story, and you can already picture what you would improve. Due diligence gives you the space to test that first impression before it becomes a financial commitment.
If you are considering a business for sale in Toronto, your review should answer three practical questions: Are the earnings dependable? Can the business keep operating through an ownership change? Do the price and deal terms reflect the risks you would take on? The answers sit across financial records, contracts, customer relationships, employees, assets and day-to-day operations.
This guide explains what to ask for, how to compare the seller’s claims with the evidence and which findings deserve closer attention from your accountant, lawyer, lender and other advisors. The aim is a decision you can defend after the excitement of the opportunity has settled.
Begin With Fit, Access and a Clear Review Process
Due diligence works best when it starts with your acquisition criteria, not a long document request. Define the type of business you want to operate, the amount of capital you can commit, the return you expect and the role you are prepared to take after closing. A profitable company can still be a poor acquisition when it depends on skills, hours or relationships you cannot readily replace.
Before receiving sensitive information, buyers commonly sign a confidentiality agreement. A letter of intent may follow once there is enough information to outline a proposed price, transaction structure and key conditions. Your lawyer should advise you on which parts of that letter are binding, including confidentiality or exclusivity provisions, and how much time the agreement gives you to complete your review.
Set up a document request list and a central place for questions. Assign each part of the review to the person qualified to assess it. Your accountant can test the quality of earnings and working-capital needs. Your lawyer can review ownership, contracts, litigation, employment matters and the proposed structure. A lender may focus on debt capacity, security and cash flow. Industry or technical specialists can examine equipment, licences, technology or environmental exposure when those areas matter.
The review period should begin after the seller has provided the agreed core documents, since missing records can consume much of the available time. Keep a running issue log that records the evidence received, the unanswered question, the person responsible and the effect on the deal. This turns a large volume of files into a decision process rather than a filing exercise.
Test the Financial Performance Behind the Asking Price
The financial review should show how the company actually earns money and how much cash may remain for debt payments, reinvestment and your compensation. Start by reconciling financial statements, corporate tax returns, bank records and sales reports over several years. Consistent figures across these sources carry more weight than a spreadsheet prepared specifically for the sale.
Small businesses are often discussed using seller’s discretionary earnings, or SDE. This usually starts with profit and adds back items such as the owner’s compensation, interest, taxes, depreciation and certain owner-specific or one-time expenses. Each add-back needs evidence. An expense only improves normalized earnings when it will genuinely disappear after you take over. If the business needs to hire someone to replace the seller’s work, that replacement cost belongs in your forecast.
For a larger company, you may see EBITDA, which means earnings before interest, taxes, depreciation and amortization. SDE and EBITDA are useful starting points, but neither tells you how much cash the business needs to operate. Compare them with capital spending, inventory requirements, accounts receivable, accounts payable and seasonal borrowing.
| Review area | What to compare | What the comparison helps you understand |
| Revenue | Tax returns, bank deposits, invoices and sales reports | Whether reported sales are complete, recurring and supported by records |
| Normalized earnings | Reported profit, proposed add-backs and the cost of replacing the owner | The earnings likely to remain under new ownership |
| Gross margin | Results by product, service, customer or location over time | Which parts of the company create profit and where margins are changing |
| Working capital | Receivables, payables, inventory and monthly cash balances | How much cash the business needs to operate after closing |
| Capital needs | Equipment age, maintenance records and planned replacements | Which near-term investments should be included in your total purchase cost |
A monthly view is especially useful in Toronto businesses affected by seasonality, contract cycles or weather. Annual totals can hide a slow period that requires extra working capital. Ask how receivables age, which inventory moves slowly and whether supplier payments have been stretched to improve the cash balance before sale.
Then build your own forecast. Use assumptions you can explain for sales, margins, payroll, rent, financing and owner compensation. Run a downside case with lower revenue or the loss of a major customer. A deal should still leave enough room to operate when results are less favourable than the seller’s projection.
See How the Business Operates Without Its Current Owner
Financial records describe past results. Operational due diligence helps you decide whether those results can continue after the owner leaves. Spend time understanding how work enters the company, who makes key decisions, which systems hold important information and where customers or employees rely personally on the seller.
Owner dependence can appear in subtle ways. The owner may approve every quote, hold the only supplier relationship or carry technical knowledge that has never been documented. A transition agreement can transfer some of that knowledge, but it cannot instantly recreate trust or experience. Estimate the time and cost required to distribute those responsibilities after closing.
Focus your operational review on evidence that shows how the company performs in ordinary conditions:
- Customers: Review revenue by customer, repeat-purchase patterns, churn, contract terms and the strength of relationships beyond the owner. A large concentration can make one renewal unusually important to the purchase.
- Employees: Understand roles, compensation, tenure, vacancies, accrued obligations and which people are essential to service delivery. Consider how and when employees will learn about a transaction with advice from your legal team.
- Suppliers: Check pricing, payment terms, minimum orders, exclusivity and the availability of alternatives. Confirm whether important agreements continue after a change of control.
- Processes and systems: Look for current procedures, reliable reporting, data backups, access controls and clear ownership of software accounts. Informal workarounds often create extra transition work.
- Assets and facilities: Inspect equipment, inventory and premises. Compare what you see with asset lists, maintenance records, leases and expected replacement costs.
Toronto location economics also deserve attention. Review rent increases, renewal options, assignment or change-of-control clauses, parking and access, zoning or permitted use, and whether the customer base depends on the current site. If the lease cannot be assigned on acceptable terms, the value of an otherwise healthy operation may change sharply.
The strongest transition plan identifies what must happen before closing, during the first week and through the first several months. It should cover introductions to key customers and suppliers, employee communication, system access, training, retained support from the seller and measurable handover milestones.
Review Contracts, Liabilities and Transaction Structure
Legal due diligence establishes what you would own, which obligations could follow the transaction and whether the company has the rights it needs to operate. Your acquisition lawyer should tailor the review to the business and advise you on the difference between buying shares of a corporation and buying selected assets.
In a share purchase, you acquire the corporation itself, including its history, contracts, assets and liabilities, subject to the protections negotiated in the agreement. In an asset purchase, you select the assets and agreed liabilities being transferred. The structure can affect taxes, third-party consents, licences, employees and financing, so it should be planned with legal and tax advisors early enough to influence the offer.
The review commonly includes corporate records, ownership of shares and assets, financing agreements, security registrations, tax matters, lawsuits or claims, insurance, employment agreements, intellectual property, privacy practices and regulatory compliance. For an Ontario acquisition, your lawyer may search the Personal Property Security Registration system to identify registered interests against business assets. A registration does not answer every question by itself, but it can reveal a claim that must be understood or discharged.
Read significant customer, supplier and lease agreements closely. Look for renewal dates, termination rights, price commitments, exclusivity, performance obligations and clauses triggered by an ownership change. Compare the signed contract with how the relationship works in practice. A customer described as recurring may buy under short purchase orders, while a valuable long-term agreement may depend on consent to transfer.
Confirm exactly what is included in the purchase. The list may cover equipment, inventory, receivables, deposits, telephone numbers, domains, software, intellectual property, customer information and the business name. Ownership and transferability matter as much as physical possession. Your lawyer can also help shape representations, warranties, indemnities, holdbacks and closing conditions around the risks discovered.
Treat Gaps and Inconsistencies as Questions With Consequences
A red flag is a reason to investigate and price risk, not an automatic verdict. Some issues have a straightforward explanation and a practical fix. Others affect the company’s value, financing eligibility or ability to operate after closing. The useful question is what the finding changes.
Pay close attention when financial records do not reconcile, important documents arrive late, add-backs lack support or projections depend on a sharp improvement with no operating plan. Similar concern is warranted when one customer creates a large share of revenue, the seller controls most relationships, key employees are expected to leave or a major contract can end on a change of ownership.
Operational and legal issues can be equally important. Deferred equipment maintenance may require immediate capital. Informal employment practices may create obligations that were absent from the forecast. A lease near expiry can weaken continuity. Missing licences, unresolved claims, weak data controls or unclear ownership of intellectual property can limit what you are actually buying.
For each material issue, choose a response that fits the evidence. You may request more information, obtain a specialist opinion, revise the valuation, change the asset or share structure, adjust working capital, add a closing condition, negotiate a holdback or seek a specific contractual protection. If the issue cannot be measured or controlled within your risk tolerance, stepping away can protect capital for a stronger opportunity.
Watch how the seller responds as well. A well-prepared seller may still need time to retrieve older documents, but the process should become clearer as questions are answered. Repeatedly changing explanations or restricting reasonable access increases uncertainty. Your advisors can help distinguish normal transaction friction from a risk that affects the deal.
Use the Findings to Shape the Offer and the Handover
Due diligence should produce a decision memo, not simply a completed checklist. Summarize the earnings you believe are sustainable, the working capital and capital spending required, the main dependencies, the unresolved risks and the conditions needed to close. This gives you a consistent basis for discussions with the seller, lender and advisors.
The findings may support the original offer. They may also justify a different price, seller financing, an earnout tied to future performance, a holdback, revised working-capital target or a longer transition period. The right response depends on which party can best control the risk and how reliably the outcome can be measured. Your lawyer and accountant can explain the consequences of each option.
An independent business valuation can provide another reference point, especially when the asking price relies heavily on discretionary add-backs, growth assumptions or intangible value. Valuation and due diligence answer related but different questions. Valuation estimates what the company may be worth under defined assumptions; due diligence tests whether those assumptions are supported.
Plan for the first 100 days before closing. Decide which relationships need an immediate introduction, which approvals or accounts must transfer, how employees will be informed and which performance measures you will watch. Add the costs and time of that transition to your investment case. A purchase that works only when every improvement happens quickly leaves little margin for the realities of taking over.
