Buying a Business in Canada: Due Diligence Checklist
A 15-point framework to minimize risk and maximize value when buying a business — covering financial, legal, operational, and commercial due diligence.
Buying a business is the single most consequential financial decision most entrepreneurs will ever make. Approximately 75,000 small and medium businesses change hands in Canada each year — yet the majority of first-time buyers overpay and inherit hidden liabilities. A rigorous due diligence process is your best protection. This checklist walks you through every critical area of investigation.
The Complete 15-Point Due Diligence Checklist
Review Financial Statements (3+ Years)
Request three years of tax returns, audited or reviewed financial statements, and monthly bank statements. Verify that reported revenue matches actual deposits. Red flags: declining revenue trends, inconsistent margins, or incomplete records.
Legal Structure and Corporate Records
Verify the corporate structure, minute books, shareholder agreements, and registered business names. Missing or incomplete corporate records are surprisingly common and must be resolved before closing.
Review All Material Contracts
Examine supplier agreements, customer contracts, lease agreements, equipment leases, franchise agreements, and partnership deals. Identify any change-of-control provisions that could trigger termination or renegotiation.
Verify Assets and Equipment
Confirm ownership, condition, and market value of all tangible assets — equipment, vehicles, real estate, inventory. Check for liens, financing agreements, and depreciation schedules.
Analyze Liabilities and Debt
Identify all outstanding debt, loan agreements, lines of credit, and contingent liabilities. Understand the repayment terms, interest rates, and any personal guarantees that need to be released upon sale.
Assess Tax Obligations and History
Review CRA filings, outstanding tax liabilities, audit history, and tax elections made. Ensure there are no pending reassessments or unresolved disputes. Structuring the deal as an asset vs. share purchase has significant tax implications.
Evaluate Employees and Management
Review employment contracts, compensation, benefits, and organizational structure. Identify key personnel whose departure could destabilize the business. Assess culture, turnover rates, and any pending labour disputes.
Analyze Customer Concentration
Map revenue by customer. If any single customer represents more than 15% of total revenue, the business carries concentration risk that must be priced into your valuation and addressed in your post-purchase plan.
Review Supplier and Vendor Relationships
Identify critical suppliers, contract terms, pricing agreements, and any exclusivity clauses. Understand the supply chain concentration — a business dependent on one key supplier is vulnerable.
Assess Market Position and Brand
Evaluate the company’s reputation, online reviews, brand recognition, and market share. Talk to customers directly if the seller permits. A strong brand is an asset; a damaged reputation is a liability that takes years to repair.
Analyze the Competitive Landscape
Identify current competitors, new entrants, substitute offerings, and industry trends. A business that dominates a shrinking market is a riskier acquisition than a smaller player in a growing one.
Conduct an Independent Valuation
Apply at least two valuation methods — income approach (discounted cash flow or capitalized earnings) and market approach (comparable transactions). Reconcile the results and factor due diligence findings into your offer. See our Business Valuation service.
Structure the Financing
Evaluate your financing mix: bank senior debt, seller financing, BDC acquisition loans, CSBFP loans (up to $1M), and buyer equity. Ensure debt service coverage ratios are sustainable — typically 1.25x or higher.
Develop a Transition and Handover Plan
Structure the seller’s post-sale involvement — typically 3 to 12 months in a defined advisory role. Define authority boundaries, communication protocols, and exit timing clearly in the purchase agreement.
Build Your Post-Purchase Growth Plan
Your first 90 days determine whether you capture or destroy value. Plan for: key employee retention, customer communication, operational integration, and early wins that build momentum. For strategy support, see our Purchase Strategy service.
Why This Checklist Matters
Due diligence is where most deals are won or lost. Buyers who rush this phase inherit problems — unreported debt, customer concentration risk, unresolved tax liabilities, or broken supplier relationships. Sellers who are unprepared see their offers fall apart. This checklist ensures no stone is left unturned.
I have seen acquisitions where the buyer discovered post-close that 40% of revenue came from one customer who left within 60 days. I have seen missing corporate records delay closings by months and give buyers leverage to renegotiate pricing. A disciplined due diligence process catches these issues before they become your problem.
