Lawyer fees for buying an existing business in Ontario typically range from $5,000 to $15,000+ CAD. The final cost depends heavily on whether you are executing an Asset Purchase or a Share Purchase, the complexity of the legal due diligence, and the extent of required tax structuring.
Acquiring a functioning, profitable company is a fantastic way to jumpstart your entrepreneurial journey or expand your current operations. 💼 However, buying a business in Ontario is a legally complex process loaded with hidden risks. Without proper legal guidance, you could unknowingly inherit massive tax debts from the Canada Revenue Agency (CRA), face pending lawsuits from former employees, or take on faulty equipment.
This guide will break down the expected legal costs associated with purchasing a business. Whether you are acquiring a tech startup in Waterloo, a manufacturing plant in Hamilton, or a franchise in Toronto, hiring an experienced corporate law firm is the best investment you can make to protect your capital.
Step-by-Step Process in Ontario
Business acquisitions are rarely finalized in a single meeting. 📋 A corporate lawyer will guide you through several distinct phases of the transaction, and their fees are usually tied to the amount of work required at each step. Here is what the process generally involves:
Step 1: The Letter of Intent (LOI) and NDA
The process usually kicks off when your lawyer drafts a Letter of Intent (LOI) and a Non-Disclosure Agreement (NDA). The LOI outlines the basic terms of the deal, the proposed purchase price, and explicitly states whether you are buying the assets of the business or the corporation’s shares. While not always legally binding, a well-drafted LOI prevents misunderstandings before thousands of dollars are spent on due diligence.
Step 2: Legal and Financial Due Diligence
Once the LOI is signed, your law firm will begin investigating the target company. 🔍 This phase is where a large portion of your legal fees will go. Your lawyer will review the minute books, check for registered liens under the Personal Property Security Act (PPSA), review commercial leases, and ensure the seller is in good standing with the CRA and the Workplace Safety and Insurance Board (WSIB).
Step 3: Asset Purchase vs. Share Purchase Agreements
The structure of the deal dictates the complexity of the final contract. In an Asset Purchase, you buy specific items (equipment, client lists, inventory) and leave the old corporation behind, which is legally simpler. In a Share Purchase, you buy the entire corporation, meaning you inherit all its past legal and tax liabilities. Share purchases require extensive indemnity clauses and tax structuring, making the legal work significantly more expensive.
Step 4: Closing and Post-Closing Adjustments
On the closing date, your lawyer ensures all funds are transferred safely, registers new security interests, and files the necessary notices with the Ontario Business Registry. ⚔ They will also help calculate post-closing adjustments, ensuring you are credited for things like prepaid rent or unfulfilled customer contracts.
How Much Does it Cost in Ontario?
There is no flat rate for buying a business, as every transaction is unique. 💵 In 2026, most Ontario corporate lawyers bill hourly (ranging from $350 to $700+ CAD per hour), though some may offer block fees for specific phases. Here is an estimated breakdown:
- Drafting the LOI and NDA: Typically costs between $1,000 and $2,500 CAD.
- Legal Due Diligence: Reviewing leases, employee contracts, and conducting PPSA searches usually ranges from $2,000 to $5,000 CAD.
- Asset Purchase Agreement (APA): Drafting and negotiating a standard APA generally costs between $3,000 and $7,000 CAD.
- Share Purchase Agreement (SPA): Due to the higher liability risks and tax implications, drafting a comprehensive SPA can range from $5,000 to $12,000+ CAD.
- Accounting and Tax Advice: In addition to lawyer fees, expect to pay a Chartered Professional Accountant (CPA) $2,000 to $5,000 CAD to verify the seller’s financial statements.
| Purchase Structure | What You Are Buying | Average Legal Cost |
|---|---|---|
| Asset Purchase | Only the equipment, brand, and inventory | Moderate ($5,000 – $8,000 CAD) |
| Share Purchase | The entire corporation and all past liabilities | High ($8,000 – $15,000+ CAD) |
| Franchise Resale | An existing location + Franchise Agreement | Moderate ($4,000 – $7,000 CAD) |
How Long Does the Process Take?
Buying a business is a marathon, not a sprint. ⏳ From the moment you sign the Letter of Intent to the official closing date, the process generally takes between 2 to 6 months. The due diligence phase alone typically consumes 30 to 60 days. If the business relies on commercial leases or franchise agreements, the timeline can be delayed further, as you must wait for the landlord or the franchise head office to approve the transfer of the agreements to your name.
Frequently Asked Questions (FAQ)
Can I just use the seller’s lawyer to save money?
No. A single law firm cannot represent both the buyer and the seller in a business acquisition because it is a direct conflict of interest. You must hire your own independent corporate lawyer to ensure your financial interests are exclusively protected.
Why is a Share Purchase more dangerous than an Asset Purchase?
When you buy shares, you step into the shoes of the previous owner. If the corporation failed to pay its taxes three years ago, or if a former employee decides to sue for wrongful dismissal from before you bought the company, you and your new business are on the hook for those liabilities.
Do I need to keep the old employees?
In a Share Purchase, the employees automatically remain with the corporation. In an Asset Purchase, employee contracts are legally terminated by the seller, and you have the choice to offer them new employment contracts under your new company, though severance issues must be carefully negotiated.
What is a holdback clause?
A holdback is a negotiated amount of the purchase price that your lawyer keeps in their trust account for a specified period after closing (e.g., 6 to 12 months). This money is used to protect you just in case undisclosed debts or CRA tax audits surface after you take over.
