How to Transfer Ownership of a Private Corporation in Ontario?

27 Mar 2026 5 min read No comments Business Formation & Contracts Ontario

To transfer ownership of an Ontario private corporation, you must issue or transfer shares, formally record the change in the corporate Minute Book, and file a Notice of Change with the Ontario Business Registry within 15 days. Hiring a corporate lawyer is highly recommended to ensure compliance and avoid severe tax penalties.

Transferring ownership of a private corporation is not as simple as handing over the keys to the office. Whether you are bringing on a new business partner, passing a family business down to your children, or fully selling your company to a competitor, strict legal procedures must be followed. In Ontario, corporations are heavily regulated entities, and failing to document an ownership change correctly can lead to massive headaches with the Canada Revenue Agency (CRA) or bitter shareholder disputes.

For private businesses operating in cities like Toronto, Mississauga, or London, transferring ownership means properly transferring shares. Unlike publicly traded companies on the stock market, private corporations usually have heavy restrictions on who can buy or sell shares. We will guide you through the step-by-step legal process of executing a share transfer, updating your corporate records, and ensuring the Ontario government is properly notified of your new corporate structure. 📈

Step-by-Step Process for Transferring Shares in Ontario

A corporate transfer requires meticulous paperwork. A simple handshake or an informal email is completely legally invalid when it comes to corporate ownership. The transaction must be properly papered in your company’s official records. 📄

Step 1: Review the Articles and Shareholders’ Agreement

Before you transfer any shares, your lawyer must review the company’s Articles of Incorporation and the Shareholders’ Agreement (if one exists). In Ontario, most private corporations have a mandatory “restriction on share transfers.” This usually means you cannot legally sell or give your shares to an outside party without first obtaining the formal, written consent of the majority of the current directors or offering the shares to the existing partners first (a Right of First Refusal).

Step 2: Draft the Share Transfer Documents

Once you have the necessary approvals, the legal paperwork must be drafted. The seller must sign a Share Transfer document, and the existing physical share certificate must be canceled. The Board of Directors must then pass and sign a formal Corporate Resolution officially approving the transfer of ownership to the new buyer. The buyer will then be issued a brand-new share certificate reflecting their exact ownership percentage. 📝

Step 3: Update the Corporate Minute Book

Every corporation in Ontario is legally required to maintain a physical or digital Minute Book. This is the master record of the company. The Minute Book contains the registers of all directors, officers, and shareholders. When ownership changes, your law firm will update the Shareholder Register and the Securities Transfer Register inside the Minute Book. If the CRA ever audits the company, an up-to-date Minute Book is the absolute first thing they will demand to see.

Step 4: File a Notice of Change with the Province

If the transfer of shares also results in a change to the Board of Directors (for example, the old owner resigns as a director and the new owner is appointed), you must update the government. Under Ontario law, you are required to file a Notice of Change (Form 1 under the Corporations Information Act) with the Ontario Business Registry within exactly 15 days of the change. This updates the public record so banks and creditors know who is legally running the business. ⚖️

How Much Does it Cost in Ontario?

The cost of transferring ownership depends entirely on how organized the company’s current records are and whether there is a dispute between partners.

Legal / Government ServiceEstimated Cost (CAD)What is Included
Basic Share Transfer (Law Firm)$1,000 – $3,500+Drafting resolutions, canceling/issuing certificates, and updating the Minute Book.
Minute Book Reconstruction$1,500 – $4,000If you have lost your original Minute Book, lawyers must legally recreate years of records.
Ontario Notice of Change$0 (Online)Filing the government form directly via the Ontario Business Registry portal is free.

It is also highly recommended to consult a corporate accountant before transferring shares, as capital gains taxes will likely apply. Accounting fees for tax structuring during a corporate buyout typically add an additional $1,500 to $5,000+ CAD.

How Long Does the Process Take?

If all parties are in complete agreement, the legal paperwork for a standard share transfer can be drafted, signed, and finalized very quickly, usually within 1 to 3 weeks. ⌚

However, if the corporation’s Minute Book has been severely neglected for years, your lawyer will have to spend weeks reconstructing the past corporate history before they can legally execute the new transfer. Furthermore, if existing shareholders dispute the valuation of the shares or refuse to sign their required consent forms, the process can easily be delayed by several months.

Frequently Asked Questions (FAQ)

Do I absolutely need a lawyer to transfer shares?

While not strictly mandated by law, doing it yourself is incredibly risky. If you make a mistake on the corporate resolutions or fail to update the registers correctly, the transfer may be deemed legally void, causing massive tax and ownership disputes down the road.

What happens if I forget to file the Notice of Change?

If you fail to file the Notice of Change with the Ontario Business Registry within 15 days, the public record remains outdated. The old owner may still be held legally liable for the corporation’s actions, and the company could face administrative penalties or eventually be dissolved by the government.

Are there tax consequences when transferring shares?

Yes, significant ones. When you sell or transfer shares that have increased in value, the CRA will heavily tax the capital gain. Even if you “gift” the shares to a family member for $0, the CRA deems the transfer to have happened at Fair Market Value, triggering immediate taxes.

What is a Corporate Minute Book?

A Minute Book is the official binder (or secure digital file) that holds the corporation’s entire legal history. It contains the Articles of Incorporation, the corporate by-laws, the registers of shareholders and directors, and all signed resolutions from board meetings.

Can an existing shareholder block me from selling?

It is very possible. If your company has a strongly drafted Shareholders’ Agreement, it usually outlines exact rules for selling. This often includes a “Right of First Refusal,” meaning you must offer your shares to your current partners first before selling them to an outside buyer.
