How to Change Ownership of a Corporation in Ontario

Changing the ownership of an Ontario corporation is usually accomplished by changing who owns its shares.

That can happen in several different ways. One shareholder may sell shares to another person. The corporation may issue new shares to an incoming owner. An existing shareholder may be bought out. Shares may be transferred to a holding company as part of a corporate reorganization. In other situations, the corporation itself may purchase or redeem a shareholder’s shares.

I’m Raz Toor, the founder of Falcon Law PC. We regularly assist Ontario business owners with share transfers, shareholder buyouts, new share issuances, holding-company structures, corporate reorganizations, shareholder agreements and the purchase and sale of privately held businesses.

The important point is that “changing ownership” is not simply a matter of changing a name with the Ontario government. For a private corporation, the legal ownership of the company is primarily reflected in its shares and corporate records.

What Does Ownership of a Corporation Mean?

A corporation is a separate legal entity from the people who own it.

The owners are generally the corporation’s shareholders.

A shareholder may own:

• voting common shares;
• non-voting common shares;
• preferred shares;
• multiple classes of shares with different rights; or
• another class or series permitted by the corporation’s articles.

The rights attached to those shares can differ significantly.

For example, one class may carry voting control while another class participates economically but does not vote.

That means a change in the number of shares does not necessarily produce the same change in voting control, dividend rights or value.

Changing a Shareholder Is Not the Same as Changing a Director

This distinction causes frequent confusion.

A shareholder owns shares in the corporation.

A director participates in the governance of the corporation.

An officer may hold a position such as president, secretary or treasurer.

One person can be all three, particularly in a small owner-operated company, but the roles are legally distinct.

If one shareholder sells all of their shares, they do not necessarily cease to be a director or officer unless the transaction also deals with those positions.

Likewise, changing directors does not automatically change the ownership of the corporation.

What Are the Main Ways to Change Ownership?

For a private Ontario corporation, the most common structures are:

• transferring existing shares from one shareholder to another;
• selling shares to an outside purchaser;
• issuing new shares to a new or existing shareholder;
• buying out an existing shareholder;
• having the corporation purchase or redeem shares;
• transferring shares to a holding company;
• transferring shares between family members;
• implementing an estate or succession plan; or
• completing a larger corporate reorganization.

The correct structure depends on what the owners are actually trying to accomplish.

Option 1: Transfer Existing Shares to Another Person

The simplest ownership change may occur where an existing shareholder sells or transfers some or all of their shares.

For example, suppose two founders each own 50 common shares.

If one founder transfers 20 shares to the other founder, the ownership can move from:

• 50/50 before the transfer; to
• 70/30 after the transfer.

The corporation itself has not issued any additional shares. Existing shares have simply changed hands.

A share transfer may require:

• a share purchase or transfer agreement;
• review of the corporation’s articles;
• review of any shareholder agreement;
• director approval where required;
• share-transfer documentation;
• cancellation or endorsement of existing share certificates;
• issuance of replacement certificates where applicable;
• updates to the securities register;
• updates to the transfer register;
• updates to beneficial-ownership records where applicable; and
• related minute-book documentation.

Check the Articles Before Transferring Shares

Private corporations commonly contain restrictions on the transfer of their shares.

For example, the articles may state that no shares can be transferred without approval of:

• the directors;
• the shareholders;
• a specified percentage of shareholders; or
• another person identified in the articles.

Those restrictions are particularly common because many privately held corporations were structured to qualify as private issuers under Canadian securities laws.

A shareholder should therefore not simply sign a piece of paper purporting to transfer their shares without reviewing the corporation’s governing documents.

Check the Shareholder Agreement

A shareholder agreement may create additional restrictions.

It may contain:

• rights of first refusal;
• rights of first offer;
• pre-emptive rights;
• permitted-transfer provisions;
• family-transfer provisions;
• shotgun clauses;
• buy-sell mechanisms;
• tag-along rights;
• drag-along rights;
• vesting provisions;
• founder repurchase rights; and
• restrictions on who may become a shareholder.

A transfer completed contrary to the shareholder agreement can create significant problems.

Option 2: Sell the Corporation to a New Owner

A change of ownership may involve selling all or substantially all of the outstanding shares to an outside purchaser.

That is a share purchase transaction.

The buyer acquires the corporation itself rather than purchasing individual assets from it.

The corporation continues to own its:

• bank accounts;
• equipment;
• inventory;
• contracts;
• leases;
• employees;
• intellectual property;
• accounts receivable;
• licences; and
• existing liabilities.

Only the ownership of the shares changes.

This is very different from an asset purchase, where the purchaser selects particular assets and liabilities to acquire.

For a detailed comparison, see our guide on asset purchases versus share purchases in Ontario.

Due Diligence Still Matters in a Share Transfer

Where a third party is acquiring the corporation, the purchaser will normally want to conduct due diligence.

Depending on the business, that may include reviewing:

• articles and corporate records;
• share ownership;
• financial statements;
• tax returns;
• material contracts;
• commercial leases;
• bank debt;
• security registrations;
• employees and contractors;
• litigation;
• intellectual property;
• licences and permits;
• customer obligations;
• shareholder loans; and
• other liabilities.

Our business purchase and sale practice assists with larger ownership changes involving the acquisition or sale of an operating company.

Option 3: Issue New Shares to a New Owner

Another way to change ownership is for the corporation to issue new shares.

This is fundamentally different from one shareholder transferring existing shares to another shareholder.

Suppose one founder owns 100 shares.

If the corporation issues 100 equivalent new shares to an investor, the original owner may move from:

100% ownership to 50% ownership.

The founder has not sold any of their existing shares. Instead, their ownership has been diluted because additional shares are now outstanding.

New Share Issuances Require Corporate Approval

The board generally needs to approve the issuance of shares.

The corporation should confirm:

• which share class is being issued;
• how many shares are being issued;
• the subscription price;
• the consideration received by the corporation;
• the rights attached to the shares;
• whether existing shareholders have pre-emptive rights;
• whether the shareholder agreement restricts the issuance;
• whether securities-law requirements are satisfied; and
• how the issuance affects the capitalization table.

The issuance should then be reflected in the corporation’s securities register and minute book.

Be Precise About Percentages

I often see business owners say that someone is receiving “5% of the company” without specifying what that actually means.

The documentation should ideally establish:

• the exact number of shares;
• the class of shares;
• the rights attached to that class;
• the percentage of issued and outstanding shares;
• the voting percentage;
• the percentage on a fully diluted basis, where relevant; and
• whether future issuances will dilute that percentage.

Five percent of one non-voting share class is not necessarily the same thing as five percent of the economic value or voting control of the corporation.

Option 4: One Shareholder Buys Out Another

Ownership often changes because one founder or business partner is leaving.

The remaining shareholder may purchase the departing owner’s shares.

That transaction raises additional issues involving:

• valuation;
• shareholder agreements;
• purchase-price financing;
• shareholder loans;
• personal guarantees;
• director resignations;
• releases;
• restrictive covenants;
• deferred payments; and
• tax treatment.

For more detail, see our guide on how to buy out a business partner in an Ontario corporation.

Option 5: The Corporation Purchases Its Own Shares

Instead of another shareholder purchasing the departing owner’s shares, the corporation itself may sometimes purchase or redeem shares.

That can also change the relative ownership percentages of the remaining shareholders.

However, a corporate redemption or purchase is not interchangeable with a shareholder-to-shareholder transaction.

Ontario corporate-law solvency restrictions apply, and the income-tax treatment can differ substantially.

For example, a corporate redemption or acquisition of shares can generate deemed-dividend treatment under the federal Income Tax Act.

The structure should therefore normally be reviewed with the corporation’s accountant or tax adviser before the documents are finalized.

Option 6: Transfer Shares to a Holding Company

A business owner may also change the legal ownership of an operating company as part of a corporate reorganization.

For example:

Before restructuring:

Individual → Operating Company

After restructuring:

Individual → Holding Company → Operating Company

The shareholder has not necessarily sold the business to an unrelated buyer. Instead, ownership has been reorganized so that a holding corporation now owns the operating-company shares.

Depending on the circumstances, a transfer of eligible property to a Canadian corporation may be structured using a joint election under section 85 of the federal Income Tax Act to defer otherwise immediate tax consequences.

The tax structure should be designed by or coordinated with the client’s accountant or tax adviser.

A Holding-Company Rollover Requires More Than Incorporating a HoldCo

Simply incorporating a holding company does not make it the owner of the operating business.

The operating-company shares must actually be transferred.

A rollover can involve:

• incorporating the holding company;
• confirming the existing share ownership;
• valuing the shares where required;
• preparing the share-transfer agreement;
• issuing holding-company shares as consideration;
• preparing director and shareholder resolutions;
• updating both corporations’ securities registers;
• preparing the necessary corporate records;
• coordinating section 85 elected amounts; and
• coordinating the required tax election with the accountant.

Option 7: Transfer Shares to a Spouse or Family Member

Ownership can also change as part of family, succession or estate planning.

Examples include:

• bringing a spouse into ownership;
• transferring growth shares to family members;
• implementing an estate freeze;
• transferring shares to adult children;
• introducing a family trust; or
• creating different voting and non-voting share classes.

These transactions can have significant income-tax consequences.

Attribution rules, tax on split income, capital gains, paid-up capital, adjusted cost base and estate-planning considerations may all be relevant.

I would therefore generally coordinate this type of ownership restructuring with the client’s accountant or tax adviser before issuing or transferring shares.

Do You File a “Change of Shareholder” With the Ontario Government?

Usually not in the way many business owners expect.

For a private Ontario corporation, shareholders are generally tracked through the corporation’s own securities register and transfer register.

Ontario’s Business Corporations Act requires the corporation to maintain a securities register identifying registered shareholders and their holdings, as well as a register recording transfers of securities.

Accordingly, a straightforward transfer of shares does not generally involve simply logging into the Ontario Business Registry and replacing the name of the old shareholder with the new shareholder.

The corporate records are critical.

When Would an Ontario Business Registry Filing Be Required?

A share transfer may occur alongside other changes that do require a government filing.

For example:

• a director may resign;
• a new director may be appointed;
• the registered office may change;
• officer information may change;
• the corporation’s legal name may change;
• the articles may need to be amended; or
• other publicly recorded corporate information may change.

Those matters may require a Notice of Change, Articles of Amendment or another Ontario Business Registry filing.

The ownership transaction and the government filing should therefore be treated as related but separate questions.

Beneficial Ownership Records Must Also Be Updated

Privately held Ontario business corporations are also required to maintain information concerning their individuals with significant control.

An individual can generally be considered to have significant control where, among other circumstances, they own, control or direct:

• 25% or more of the corporation’s voting shares; or
• shares representing 25% or more of the fair market value of all outstanding shares.

Control can also arise through certain direct or indirect influence arrangements.

This information is maintained internally by the corporation rather than being filed in a public Ontario shareholder registry.

Ontario currently requires a private corporation to update its beneficial-ownership information within 15 days after becoming aware of a relevant change and to review the information at least annually.

A material ownership change should therefore trigger a review of this register as part of the closing.

What Should Be Updated in the Minute Book?

Depending on the transaction, the corporate records may need to include:

• share purchase agreements;
• share-transfer forms;
• share subscriptions;
• director resolutions;
• shareholder resolutions;
• share certificates;
• cancelled share certificates;
• the securities register;
• the transfer register;
• the register of individuals with significant control;
• director and officer registers;
• shareholder agreements or joinders;
• articles of amendment where necessary; and
• other transaction documentation.

The minute book should tell a coherent story of who owned the corporation before the transaction, what happened and who owns it afterward.

What if the Minute Book Is Incomplete?

This is common in privately held businesses.

The owners may know informally who owns the company, but the corporate records may be missing:

• share certificates;
• subscription agreements;
• transfer documents;
• director resolutions;
• shareholder registers;
• securities registers; or
• historical corporate changes.

Before changing ownership, I generally want to establish the current capitalization with reasonable certainty.

Corrective or reconstruction work may therefore be required before the new transaction is documented.

Do You Need a Share Purchase Agreement?

Not every internal transfer requires a lengthy acquisition agreement.

For example, a nominal transfer involving a dormant corporation with no liabilities may justify relatively simple documentation.

A substantial operating-business acquisition is very different.

A share purchase agreement may need to address:

• purchase price;
• payment terms;
• working capital;
• debt;
• share ownership;
• corporate records;
• tax matters;
• employees;
• contracts;
• litigation;
• representations and warranties;
• indemnification;
• closing conditions;
• holdbacks;
• restrictive covenants;
• transition assistance; and
• post-closing obligations.

The documentation should be proportionate to the transaction.

What Happens to the Corporation’s Assets When Ownership Changes?

In a share transfer, the corporation generally continues owning the same property.

For example, if a corporation owns:

• $100,000 in its bank account;
• vehicles;
• equipment;
• a website;
• trademarks;
• customer contracts; and
• accounts receivable,

those assets are not ordinarily transferred merely because the corporation’s shares change hands.

The shareholder owns shares in the corporation. The corporation owns its own assets.

The Corporation’s Liabilities Also Remain

The same principle applies to liabilities.

Changing shareholders does not normally erase:

• tax debt;
• bank loans;
• supplier obligations;
• lease liabilities;
• employee obligations;
• litigation;
• warranties;
• customer deposits; or
• other corporate liabilities.

This is why purchasers buying the shares of an operating company generally conduct meaningful due diligence.

Review Change-of-Control Clauses

Even though the corporation remains the same entity, certain contracts may treat a change in ownership as a significant event.

The transaction may require notice or consent under:

• banking agreements;
• commercial leases;
• franchise agreements;
• government contracts;
• licence agreements;
• distribution agreements;
• major customer contracts;
• shareholder agreements;
• insurance policies; and
• regulatory licences.

A business owner should therefore not assume that because the legal entity is unchanged, no third-party approvals are required.

What Happens to Personal Guarantees?

A share transfer also does not automatically release a former shareholder from personal guarantees.

They may have guaranteed:

• the corporation’s bank debt;
• a commercial lease;
• equipment financing;
• a franchise agreement;
• supplier credit; or
• another obligation.

Where an owner is exiting completely, those guarantees should be identified and dealt with as part of the ownership-change transaction.

Tax Advice Should Come Before the Transfer

The legal documentation and tax structure should be coordinated.

Potential tax issues can include:

• capital gains;
• adjusted cost base;
• paid-up capital;
• lifetime capital gains exemption eligibility;
• section 85 rollovers;
• share redemptions;
• deemed dividends;
• tax on split income;
• estate freezes;
• family transfers; and
• corporate reorganizations.

A lawyer can implement the corporate structure, but the accountant should generally advise on the intended tax result.

What We Have Been Working On in 2026

Our corporate work in 2026 has included several different types of ownership changes, illustrating why there is no single “change of ownership” form.

In one matter, we advised on the acquisition of a dormant Ontario corporation for nominal consideration. There was no intended change to the directors or officers, so the transaction was primarily a share-transfer and corporate-records exercise rather than a major government-filing process. The work involved the share purchase documentation, transfer records, corporate resolutions and updates to the corporation’s registers and minute book. :chatgpt-content-reference{index=”0″}

In another 2026 restructuring, two owners transferred all of their shares in an operating company to a newly established holding corporation as part of a section 85 rollover. The ownership of the operating business moved from the individuals directly to their holding corporation while the individuals received shares of the holding corporation as consideration. :chatgpt-content-reference{index=”1″}

We then worked on a further share transfer within that ownership structure that changed the shareholders’ interests from approximately 60/40 to 70/30. That transaction required an actual transfer of existing voting shares and corresponding updates to the corporate records. :chatgpt-content-reference{index=”2″}

We have also worked on new equity issuances for early-stage businesses where incoming advisers or participants were receiving newly issued shares rather than purchasing existing founder shares. In those situations, calculating the precise post-issuance percentage, documenting the subscription and updating the capitalization records were central to the transaction. :chatgpt-content-reference{index=”3″}

Those examples all involve a “change in ownership,” but legally they are four different transactions.

The examples above have been anonymized and certain details have been generalized to protect client confidentiality.

Example 1: One Founder Sells to the Other

Suppose Alex and Jordan each own 50 voting common shares.

Jordan wants to reduce their ownership to 20%.

Jordan could sell 30 of their existing shares to Alex.

After the transaction:

• Alex owns 80 shares;
• Jordan owns 20 shares; and
• 100 shares remain outstanding.

No new shares were issued.

Example 2: The Corporation Brings in a New Investor

Suppose Alex owns all 100 existing shares.

The corporation wants a new investor to own 20% after closing.

Rather than Alex selling shares, the corporation can potentially issue new shares to the investor.

The number of new shares must be calculated based on the intended post-closing capitalization.

The money paid for those new shares generally goes to the corporation rather than to Alex personally.

That distinction can be commercially important.

Example 3: Founder Creates a Holding Company

A founder owns 100 shares of OpCo personally.

The founder incorporates HoldCo and transfers the OpCo shares to HoldCo as part of an appropriately structured rollover.

After completion:

• the founder owns HoldCo; and
• HoldCo owns OpCo.

The beneficial economic owner may ultimately remain the same individual, but the legal ownership chain has materially changed.

Example 4: One Owner Leaves Completely

Suppose two owners each hold 50%.

One owner wants to retire.

The parties might structure the exit as:

• a purchase by the remaining shareholder;
• a purchase or redemption by the corporation;
• a combination of those approaches; or
• a sale of the entire company to a third party.

The appropriate structure may depend heavily on financing and tax considerations.

A Practical Ontario Corporate Ownership Change Checklist

Before implementing an ownership change, I generally want to confirm:

• Is the corporation actually incorporated in Ontario?
• Who are the current registered shareholders?
• How many shares does each shareholder own?
• What classes of shares are outstanding?
• What rights attach to those shares?
• Are the corporate records current?
• Is there a shareholder agreement?
• Are there share-transfer restrictions?
• Does a right of first refusal apply?
• Are pre-emptive rights relevant?
• Are existing shares being transferred?
• Are new shares being issued?
• Is the corporation redeeming shares?
• What is the intended ownership percentage after closing?
• What is the purchase or subscription price?
• Has the tax structure been reviewed?
• Are shareholder loans involved?
• Are personal guarantees involved?
• Do contracts contain change-of-control provisions?
• Are director or officer changes occurring?
• Are Ontario Business Registry filings required?
• Does the significant-control register need to be updated?
• What corporate resolutions are required?
• What share certificates must be issued or cancelled?
• Has the securities register been updated?
• Has the transfer register been updated?

Common Mistakes When Changing Corporate Ownership

Some recurring problems include:

• assuming ownership can be changed by simply updating the Ontario Business Registry;
• failing to review the articles;
• ignoring the shareholder agreement;
• not knowing how many shares are actually outstanding;
• describing an ownership percentage without specifying the share class;
• issuing new shares without considering dilution;
• transferring shares before obtaining tax advice;
• forgetting beneficial-ownership records;
• failing to obtain required director approval;
• ignoring securities-law requirements;
• not updating the minute book;
• failing to deal with shareholder loans;
• assuming personal guarantees automatically disappear;
• failing to review change-of-control clauses; and
• using informal emails or handshake arrangements for significant ownership transactions.

How Falcon Law PC Can Help

Falcon Law PC assists Ontario entrepreneurs, shareholders and privately held corporations with share transfers, ownership changes, shareholder buyouts, new share issuances, shareholder agreements, holding-company structures, section 85 reorganizations and business purchase and sale transactions.

You can learn more about our legal services for entrepreneurs and business owners.

Where the ownership change involves the acquisition or sale of an operating company, we can also assist through our business purchase and sale practice.

If you are planning an ownership change, I generally recommend providing the corporation’s articles, minute book, current securities register, shareholder agreement, share certificates and an explanation of what the owners want the structure to look like after the transaction. From there, we can determine whether the appropriate transaction is a share transfer, new issuance, redemption, reorganization or a combination of steps.

This article is intended for general informational purposes only and does not constitute legal, tax, accounting, valuation, securities or investment advice. The appropriate ownership-change structure depends on the corporation’s articles, share structure, shareholder agreements, tax circumstances and the commercial objectives of the parties.
