Buying a Private Business in Canada: The Complete Buyer’s Playbook
Buying a private business in Canada is a multi-stage process: identify the target, conduct preliminary diligence, negotiate a Letter of Intent (LOI), run formal due diligence, document the deal in a Share Purchase Agreement or Asset Purchase Agreement, and close. The most consequential decision you will make is how to structure the acquisition share purchase vs. asset purchase because that choice determines your tax position, risk exposure, and the ease of financing for years after closing. Getting legal and tax advice at the LOI stage, not after, is what separates well-structured acquisitions from expensive mistakes.
Why Deal Structure Is the First Decision Not the Last
Most buyers approach a business acquisition thinking about price. The experienced ones think about structure first, because structure determines what you actually get for the price you pay.
A share purchase means you buy the shares of the corporation. You inherit the business but also its entire history: its employees, its contracts, and every liability the corporation has ever incurred, known or unknown. The corporation continues to exist unchanged; ownership simply transfers.
An asset purchase means the corporation sells you specific assets (equipment, inventory, goodwill, customer lists, and intellectual property), and you take them into a new or existing entity. The seller keeps the corporate shell. You start with a cleaner balance sheet and limited inherited liability.
From a buyer’s perspective, asset purchases are usually preferred because you acquire a stepped-up adjusted cost base (ACB) and undepreciated capital cost (UCC) in each asset, which generates larger CCA deductions going forward, you do not inherit unknown or contingent liabilities, and you can cherry-pick the assets and contracts you want
Sellers typically prefer share sales (particularly for LCGE reasons). The structure that closes the deal is usually a negotiated outcome, and it has major implications for your legal documents, tax filings, financing, and integration.
Step 1: Finding and Evaluating a Target
Acquisitions start with identifying a business that fits your strategic or investment criteria. Buyers access private business deal flow through business brokers and M&A advisors, direct outreach, Industry relationships, and online platforms
Once a target is identified, the typical pre-LOI process includes:
Signing a Non-Disclosure Agreement (NDA): Before a seller shares financial statements or operational details, they will require a signed NDA. The NDA should be reviewed so the standstill, non-solicitation, and exclusivity provisions can have real teeth.
Reviewing the Confidential Information Memorandum (CIM): The CIM is a seller-prepared summary of the business: its history, financial performance, customer base, employees, competitive position, and asking price. Treat the numbers as a starting point, not gospel; they are compiled by the seller and will be subject to verification in due diligence.
Preliminary financial analysis: Before committing to an LOI, model the deal economics: purchase price multiple vs. trailing EBITDA, financing structure, projected returns, and a rough tax analysis of whether the proposed structure makes sense. Engage your accountant early.
Management meetings: A call or in-person meeting with the owner-operator is essential. The business may be the owner its customer relationships, institutional knowledge, and key supplier ties may live with the individual. Understanding the transition risk is part of the preliminary evaluation.
Step 2: The Letter of Intent (LOI)
The LOI is the first formal document in the deal process. It sets out the key commercial terms that will be reflected in the definitive purchase agreement.

Most of the commercial terms in the LOI are non-binding; they represent agreement in principle, not a legally enforceable obligation to close. However, the exclusivity clause, confidentiality obligations, and sometimes the deposit are binding. Walking away after signing the LOI without good reason can expose you to a claim for the deposit and potentially costs.
Do not treat the LOI as a formality. Once the seller accepts your structure and price, walking that back in the definitive agreement negotiations requires strong justification and unexpected due diligence findings, typically. It is much easier to address ambiguous terms before the LOI is signed than to renegotiate them later.
Kalfa Law Firm regularly advises buyers on LOI review and negotiation. Engaging a lawyer at this stage before the LOI is signed pays for itself many times over.
Step 3: Structuring the Acquisition Vehicle
Before you spend money on formal due diligence, confirm the entity that will make the acquisition.
Using an existing corporation: If you already operate a Canadian corporation, the acquisition may be made through it. Consider whether co-mingling your new acquisition with an existing operating business is prudent. Liability isolation argues for separation.
Incorporating a new acquisition vehicle (Holdco/Newco): Many buyers create a new corporation specifically for each acquisition. A holding company structure lets you isolate the acquired business’s liabilities, create cleaner financing arrangements, and position for a future exit or refinancing.
Federal vs. provincial incorporation: An Ontario corporation is incorporated under the Ontario Business Corporations Act (OBCA), and a federal corporation under the Canada Business Corporations Act (CBCA). For a business operating primarily in Ontario, either works, but the CBCA provides greater flexibility if the business will eventually operate across multiple provinces. There is no material difference in most private M&A transactions.
Tax structuring the acquisition: The acquisition vehicle should be structured to optimize the post-acquisition tax position.
Get tax advice on the acquisition structure before closing. The decisions made here cannot easily be undone after the fact.
Step 4: Due Diligence
Due diligence is your opportunity to verify what you are buying. In private M&A, there is no public disclosure regime. The seller’s representations in the purchase agreement are only as good as the underlying facts. Due diligence finds the facts.
Formal due diligence typically runs four to eight weeks and is organized into workstreams:
Legal due diligence
Conducted by your M&A lawyer. The review includes corporate records (minute book, share register, capitalization table, director/officer history); material contracts customer, suppliers, landlords, and lenders; license agreements with attention to change-of-control clauses, assignment rights, and termination triggers; employment and independent contractor arrangements, including any non-competition, non-solicitation, and confidentiality agreements with key employees; intellectual property ownership, registration status, any third-party claims or licenses; and litigation: any pending, threatened, or settled claims; regulatory compliance licenses; permits; environmental obligations; health and safety
Financial due diligence
Conducted by your accountant. Verifies the financial statements, normalizes earnings for owner-specific items (above-market compensation, personal expenses), validates AR aging and inventory quality, and stress-tests the working capital analysis.
Tax due diligence
Often a separate workstream from financial diligence. Reviews the corporation’s historical tax filings, assessments, outstanding CRA correspondence, HST/GST compliance, payroll tax remittances, and any tax planning transactions that may have CRA exposure.
Operational due diligence
Reviews the business model, key customer and supplier concentration, employee skills and retention, IT systems, and anything else that affects the go-forward value of the business.
Findings and their consequences
Due diligence findings fall into three categories:
- Dealbreakers: material problems that fundamentally change the value proposition (undisclosed litigation, loss of a key customer, fraudulent financial statements). These justify walking away.
- Price adjustments: issues that reduce value but not deal viability. Use findings to renegotiate the purchase price or request a specific indemnity.
- Documentation issues: things that need to be fixed or addressed in the definitive agreement (missing consents, employees without signed agreements, corporate record gaps). These become conditions, covenants, or closing deliverables.
Do not rush due diligence to keep a seller comfortable. Findings discovered after closing become your problem alone.
Step 5: The Purchase Agreement
The definitive agreement, a Share Purchase Agreement (SPA) or Asset Purchase Agreement (APA), is the legal contract that governs the acquisition. It is typically drafted by the buyer’s lawyer and negotiated over multiple rounds.
In a share purchase agreement
- Representations and warranties: the seller’s factual assertions about the corporation (financial statements are accurate, there are no undisclosed liabilities, shares are fully paid and unencumbered, all material contracts are in full force)
- Indemnification: the seller’s obligation to compensate the buyer for losses arising from any breach of a representation or warranty, subject to negotiated limits (basket, cap, survival period)
- Closing conditions: what must be true on closing day (lender financing in place, key employee retention agreements signed, regulatory approvals, third-party consents)
- Non-competition and non-solicitation: post-closing restrictions on the seller
- Purchase price adjustments: working capital true-up mechanism
In an asset purchase agreement
Everything above, plus, schedule of purchased assets, assumed liabilities, excluded liabilitie, employee matters, and consent requirements.
GST/HST on asset purchases: An asset sale is generally subject to GST/HST on the taxable portion of the purchase price. However, under ETA s. 167, if the seller and buyer jointly elect and the buyer is a GST/HST registrant acquiring a business (or part of a business) capable of independent operation, the supply can be made without tax. This election should be considered in every asset purchase; failing to file it correctly can result in a significant unplanned GST/HST cost for the buyer.

Step 6: Financing the Acquisition
Most private business acquisitions involve a mix of equity (cash the buyer contributes) and debt (borrowed funds). Common financing structures include the following:
Senior bank debt: A chartered bank or credit union lends against the assets or cash flow of the acquired business. The lender will require security (general security agreement, specific asset mortgages), financial covenants, and often a personal guarantee from the buyer. Canada’s major banks and BDC are active in acquisition financing for SME transactions.
BDC (Business Development Bank of Canada): BDC is a federal Crown corporation that provides financing for Canadian SMEs, including acquisition loans. BDC is often more flexible than chartered banks on loan-to-value ratios and deal structures.
Vendor take-back (VTB) financing: The seller finances a portion of the purchase price effectively lending the buyer part of the acquisition cost, repaid over a defined term with interest. VTBs reduce the buyer’s equity requirement and align seller and buyer incentives post-closing (the seller has a stake in the business’s continued performance). A VTB is documented as a promissory note and typically subordinated to senior bank debt.
Earnout: A deferred purchase price component tied to post-closing performance metrics (revenue, EBITDA). Earnouts bridge valuation gaps common when the seller’s projections are more optimistic than the buyer’s. They require very precise drafting to avoid disputes about measurement and accounting treatment.
SBA/CSBFL: The Canada Small Business Financing Loan Program (CSBFL) provides government-backed loans for acquiring small business equipment, leasehold improvements, and intangible assets (including goodwill, up to a cap). Not available for share purchases.
Step 7: Pre-Closing Matters
Between signing the purchase agreement and closing, several tasks run in parallel:
Regulatory and government approvals: Some industries require regulatory approval for a change of control, such as financial services, broadcasting, cannabis, and certain healthcare businesses. Identify applicable regulators early; approval timelines can be long.
Third-party consents: Material contracts with change-of-control clauses require counterparty consent before shares transfer. Key leases, customer contracts, and supplier agreements should be identified in diligence and consents solicited promptly after signing.
Financing close: If the acquisition is financed, the lender will require a conditions-precedent package before advancing funds: legal opinions, security registrations, corporate approvals, and insurance certificates.
Section 116 clearance certificate (non-resident sellers): If the seller is a non-resident of Canada, ITA s. 116 requires the buyer to withhold a portion of the purchase price (25% of the purchase price for taxable Canadian property, or 50% for certain property) unless the seller provides a CRA clearance certificate before closing. Without a clearance certificate, the buyer becomes personally liable for the withholding obligation. Identify non-resident sellers early — the CRA clearance certificate process can take months.
Employee and key-person matters: If the acquisition is contingent on retaining key employees, employment offers should be extended and accepted before closing. Key employees may also be asked to sign amended non-competition or non-solicitation agreements as a condition of closing.
Step 8: Closing
Closing is the moment the title to the shares or assets transfers and the purchase price is paid. In a private deal, closing is typically a desk closing coordinated by the lawyers for each party, involving a sequential exchange of documents and wire transfers.
At closing, the buyer typically delivers a wire transfer of the purchase price (less any deposit paid earlier and any VTB amount), an officers’ certificate confirming the buyer’s representations are still accurate, and any financing documents required by the lender, while the seller delivers share certificates endorsed in favor of the buyer (share deal) or bills of sale for each transferred asset (asset deal), resignations of directors and officers being replaced, consents and approvals obtained pre-closing, key employee agreements, corporate records (minute book, seal), and any transition services agreement.
Post-closing: The deal does not end at closing. Purchase price adjustments (working capital true-ups) typically settle 60–90 days after closing. Indemnification claims can arise for months or years. Integration of the acquired business is where the value is ultimately created or destroyed.
Total from LOI to closing: commonly 3–6 months for a standard private transaction; longer for regulated industries or complex structures.
Do You Need a Lawyer to Buy a Business in Canada?
Yes and not just for the legal documents. A good M&A lawyer adds value at every stage.
The cost of legal advice in an acquisition is a fraction of the deal value. The cost of a poorly structured deal, an undiscovered liability, or a defective closing can be measured in hundreds of thousands of dollars.
