How to Transfer Shares of a Private Corporation in Canada
Transferring shares of a private corporation in Canada is not a simple handshake and a cheque. It involves legal documentation, corporate approvals, updated corporate records, and depending on the nature and parties to the transfer, potentially significant tax consequences. Getting any part of this wrong can result in an invalid transfer, unintended tax liabilities, or a shareholder dispute.
This article covers the full picture: the corporate law mechanics of a valid transfer, the restrictions that typically apply in private companies, the documents required, and the tax considerations that should be addressed before any share transfer proceeds.
Why Private Corporation Share Transfers Are Restricted
Shares of a public company trade freely on an exchange. Private corporation shares do not. Under the Ontario Business Corporations Act (OBCA) and the federal Canada Business Corporations Act (CBCA), a key characteristic of a private corporation is that its shares are subject to restrictions on transfer. These restrictions exist because private company shareholders are often also employees, directors, or officers; bringing in an unknown third party as a shareholder can fundamentally change the business relationship.
Transfer restrictions are found in two places: the corporation’s Articles of Incorporation and the shareholders’ agreement. If a transfer violates either, it is not valid. The board of directors must approve the transfer, and any pre-emption rights held by existing shareholders must be satisfied first.
Common Transfer Restrictions in Shareholders’ Agreements
Most well-drafted shareholders’ agreements for private corporations include some or all of the following mechanisms governing share transfers.
Right of First Refusal (ROFR): Before selling shares to an outside party, the selling shareholder must first offer the shares to the other existing shareholders at the same price and on the same terms as the proposed outside sale. Existing shareholders have a defined window, typically 30 to 60 days, to exercise their right to purchase. Only if they decline can the seller proceed with the outside buyer.
Drag-Along Rights: If a majority shareholder (or defined majority) agrees to sell the corporation, they can compel minority shareholders to sell their shares on the same terms. This prevents a minority from blocking a transaction that the majority has approved.
Tag-Along Rights: The mirror of drag-along; if a majority shareholder is selling, minority shareholders have the right to participate in the same sale on the same terms, ensuring they are not left behind with a new majority they didn’t choose.
Shotgun Provisions: Either shareholder can trigger a buy-sell mechanism by offering to buy the other’s shares at a stated price. The recipient must either sell at that price or buy the offeror’s shares at the same price. This forces a clean exit when the relationship has broken down.
Transfers Triggered by Key Events: Shareholders’ agreements typically address what happens to shares if a shareholder dies, becomes disabled, is dismissed for cause, resigns, or goes personally bankrupt. These provisions ensure the corporation doesn’t end up with shares held by a deceased shareholder’s estate, a hostile ex-employee, or a trustee in bankruptcy.
If your corporation doesn’t have a shareholders’ agreement, these protections don’t exist, which means a shareholder can, in principle, transfer shares to anyone without the consent or knowledge of the other owners (subject only to the Articles). This is one of the primary reasons Kalfa Law Firm recommends that any private corporation with more than one shareholder have a properly drafted shareholders’ agreement in place.
Documents Required to Complete a Share Transfer
Once the shareholder agreement requirements have been satisfied and the board has approved the transfer, the following documents are needed to complete it.
Share Purchase Agreement: If the transfer involves a sale, a Share Purchase Agreement (SPA) sets out the purchase price, payment terms, representations and warranties, and any conditions to closing. Even a simple transfer between family members or co-founders should be documented in writing. For a more complex transaction, bringing in a new investor or selling to an outside buyer, the SPA will be a more comprehensive document. See our overview of what contracts are needed to sell a business for the broader transactional context.
Directors’ Resolution Approving the Transfer: The board of directors must pass a resolution formally approving the share transfer. This resolution should reference the transferor, transferee, number and class of shares being transferred, and the price (if any). Without this resolution, the transfer is not valid under the corporation’s constating documents.
Updated Share Certificates: The old share certificate held by the transferor must be cancelled and new certificates issued: one to the transferee for the shares acquired and one to the transferor for any remaining shares they retain. Share certificates must be signed by the appropriate officers of the corporation.
Updated Corporate Registers: The corporation’s shareholders’ ledger and share transfer register must be updated to reflect the new ownership. These are part of the corporate minute book and are the definitive record of who owns what in the company. Failing to update the registers, a surprisingly common oversight, create ambiguity about ownership that can become a significant problem in later transactions or disputes.
Government Filings: If the outgoing shareholder was also a director or officer, resignation resolutions must be prepared and a Notice of Change filed with the Ontario Business Registry (Ontario Business Registry Form 1 for OBCA corporations) or Corporations Canada (for CBCA corporations) to update the public record.
All of these steps should be coordinated by a corporate lawyer to ensure the minute book is maintained correctly from the start. For more on ongoing corporate maintenance, see our overview of annual corporate obligations.
Tax Consequences of Transferring Shares
This is where most informal share transfers go wrong. The corporate mechanics can be completed in a matter of days. The tax consequences can follow the parties for years.
Capital Gains on an Arm’s-Length Sale
When shares are sold at fair market value to an arm’s-length buyer, the seller realizes a capital gain equal to the proceeds of disposition minus the adjusted cost base (ACB) of the shares. Capital gains are included in income at the applicable inclusion rate, currently 50% for most individuals (the 2024 budget proposed raising this rate on gains above $250,000 to 66.67%, though this remains subject to legislative confirmation). The taxable gain is added to the seller’s income for the year.
For qualifying small business corporation shares, the seller may be eligible to shelter the entire gain or a significant portion of it under the Lifetime Capital Gains Exemption (LCGE). The LCGE is approximately $1.25 million per seller in 2024 and is indexed to inflation. To qualify, the shares must be shares of a Canadian-Controlled Private Corporation where at least 90% of the assets are used in an active business at the time of sale, and the 24-month holding period test is satisfied. Properly structured, a share sale to an outside buyer can be entirely tax-free up to the LCGE limit.
Non-Arm’s-Length Transfers and Section 84.1
Transfers between related parties (family members, controlled corporations, or non-arm’s-length parties) trigger additional rules that can create unexpected tax consequences.
Section 84.1 of the Income Tax Act is designed to prevent surplus stripping through non-arm’s-length share transfers. If a shareholder sells shares of a corporation to another corporation that doesn’t deal at arm’s length (for example, selling Opco shares to a personally controlled Holdco) and the proceeds exceed the paid-up capital of the shares, Section 84.1 may deem the excess to be a dividend rather than a capital gain. Dividends cannot shelter under the LCGE. The effect is to deny the capital gains treatment and the LCGE on transactions that look like a sale but are economically a surplus extraction. Section 84.1 is a trap for the uninformed. restructurings, always get legal and tax advice before transferring shares between non-arm’s-length parties.
Transfers Below Fair Market Value: Deemed Proceeds
The Income Tax Act deems proceeds of disposition at fair market value for non-arm’s-length transfers, even if the shares are transferred for less. If a parent gifts shares to a child or sells them at a discount, the parent is treated as having received fair market value, triggering a capital gain based on the full value, regardless of what was actually paid. The recipient takes the shares at their cost for tax purposes, which may also be deemed to be the fair market value.
Tax-Deferred Transfers: Section 85 Rollovers
When the goal is to transfer shares without immediately triggering a capital gain, for example, moving Opco shares into a newly created Holdco, or transferring shares to a family trust as part of an estate freeze, the Section 85 rollover allows the transfer to occur at the transferor’s adjusted cost base rather than at fair market value. The gain is deferred, not eliminated. It will be realized when the shares are eventually sold to an arm’s-length party. The rollover requires a joint election filed with the CRA and must be carefully structured.
For estate planning transfers, introducing the next generation as shareholders, implementing a freeze structure, or reorganizing ownership around a family trust, these tax-deferred mechanisms are the standard tools used in corporate reorganizations and estate freezes.
Onboarding a New Shareholder vs. Transferring Existing Shares
A share transfer involves an existing shareholder selling or gifting their shares to someone new. A new share issuance involves the corporation issuing previously unissued shares to a new shareholder directly from treasury, diluting existing shareholders rather than transferring ownership from one to another.
Both mechanisms bring a new person into the shareholder group, but the tax and legal consequences differ significantly. In a transfer, the selling shareholder realizes a gain or loss. In a new issuance, no existing shareholder sells anything, but their percentage ownership is reduced. The corporation receives the subscription proceeds directly. Which mechanism is appropriate depends on the purpose of the transaction, such as bringing in an investor, rewarding a key employee, adding a family member, or restructuring for a future sale, and should be planned with legal and tax advice before execution.
