How Can I Change My Share Structure Without Selling the Business?

Yes: share structures can be rebuilt without a sale and without tax

Changing who holds which shares of your corporation does not require selling the business, because the Act treats a genuine reorganization of the company's own capital differently from a disposition to a stranger. When you exchange old shares for new shares of the same corporation, nothing has really left your hands; the same value sits in the same company, repackaged. Parliament wrote rollover provisions for exactly this situation so that owners can adopt a sensible share structure without paying tax on gains they have not actually realized.

Owners reach for these exchanges when the share register stops matching reality. The founder holds one class of everything while a spouse or adult child now carries real responsibility. All the value and all the votes travel together when they should not.

Growth that ought to accrue to the next generation keeps piling onto shares that will be taxed in the founder's estate. Or a single common class makes it impossible to pay different amounts to different shareholders, or to slide a holding company into the structure later. The warning signs that a structure is overdue for this kind of work are covered in when a corporation should be reorganized; this page covers the machinery of the exchange itself.

Three provisions do this work, and they are not interchangeable. Section 86 handles a reorganization of capital inside one corporation. Section 85 moves shares or assets between taxpayers, including to a different corporation, under a filed election. Section 51 covers the narrow case of converting a security whose own terms make it convertible.

Most owner questions that begin with "can I change my shares" end at section 86, so that is where we start.

What a section 86 exchange actually does

A section 86 exchange lets you dispose of every share you hold of one class and receive shares of another class of the same corporation, with your tax cost carrying over so no gain is triggered. Four conditions do the heavy lifting.

The exchange must happen in the course of a reorganization of the corporation's capital, which in practice means the lawyer files articles of amendment creating or altering share classes. You must give up all the shares you own of the exchanged class, not a portion of them. What you receive must include newly issued shares of the corporation. And the whole thing happens automatically: there is no form, no joint election and no filing deadline attached to section 86 itself.

The tax accounting underneath is a straight hand-off. The adjusted cost base of your old shares flows into the new shares, so the gain you have accrued over the years is preserved, not erased, and it waits for a real disposition.

Paid-up capital, the amount that can come out of a corporation tax-free, also carries over rather than stepping up; the provision is built so a reorganization cannot manufacture new tax-free room on the way through. You are allowed to take back some non-share consideration, cash or a promissory note, alongside the new shares, and it absorbs your cost base first. That flexibility is real but limited, and it is where most of the danger lives.

Where the automatic rollover breaks

The rollover fails, in whole or in part, when the values are wrong or the consideration is greedy, and the failure is taxed immediately. Three breakage points account for nearly every problem we see:

• Too much boot. Non-share consideration soaks up your adjusted cost base first; take back more than your cost and the excess is a capital gain today. Push the note or cash beyond the paid-up capital of the old shares and part of what you receive can be taxed as a deemed dividend instead, which is worse, because dividends carry no capital gains treatment at all.
• Value shifted to a related person. If the new shares plus boot are worth less than the old shares you gave up, and the shortfall lands on a family member's shares, the Act treats the shifted value as a benefit: your rollover is denied on that portion, tax arrives now, and the lost value does not even become cost base for anyone. This is why every exchange stands on a defensible valuation and a price adjustment clause that corrects the numbers if the CRA later disagrees.
• New shares that do not hold their value. When the exchange creates fixed-value preferred shares, as in a freeze, those shares must genuinely be worth what the old shares were worth: full redemption value, no dilution by later share issues, and terms the corporation actually respects. Preferred shares with soft terms invite the same benefit problem through the back door.

One more caution sits outside section 86 itself. If the exchange hands growth or dividend-paying shares to family members, the tax-on-split-income rules decide whether dividends on those shares are taxed at the top rate. TOSI turns on whether each family member genuinely works in or has capital at risk in the business, and no share exchange changes that answer. We test TOSI before designing the classes, not after the first dividend bounces.

Section 86, section 85 or section 51: choosing the door

The right provision follows from two questions: does value stay inside the same corporation, and do you need to fine-tune the tax numbers on the way through. Section 86 is clean but rigid; section 85 is flexible but demands paperwork on a deadline; section 51 is narrow and quiet.

The practical reading of that table: if your goal is to move shares to a different corporation, section 86 cannot do it and a tax-deferred transfer under section 85 with a T2057 election is the road. The election deadline is unforgiving, the earliest filing due date among everyone involved, and a late election costs a penalty that grows with time. If your goal is to reshape classes inside one company and you do not need elected amounts, section 86 does the same job with no form at all, which is why it carries most freezes. And if the security you hold was born convertible, section 51 lets the conversion happen without a disposition, provided you take nothing but shares.

What owners actually use these exchanges for

The point of a share exchange is rarely the exchange; it is what the new structure makes possible the day after. Four uses cover most of the traffic:

• The estate freeze. Exchange growth commons for fixed-value preferreds equal to today's value, then let children, key people or a family trust subscribe for new commons at a nominal price. Your tax exposure on death stops growing; future growth accrues to them. The wider freeze context, including where holding companies fit, is laid out in our guide to corporate reorganizations for owner-managed businesses.
• Separating votes from value. A reorganization can leave you with thin voting shares that control the company while value-bearing shares sit where succession needs them, so you can hand over economics without handing over the steering wheel.
• Creating room for dividends and holdcos. Redesigned classes let different shareholders receive different dividends and let a holding company be inserted later, which matters once surplus builds and you start thinking about moving excess cash out of the operating company.
• Cleaning up history. Old classes from a departed partner, misdrafted rights, or shares that would fail the lifetime capital gains exemption tests can all be rebuilt while the clock on the exemption's 24-month holding tests is still running in your favour.

None of these require a buyer, a sale price or a taxable event. They require articles, a valuation, and a sequence done in the right order.

The facts that change the answer, and how the work runs

Whether a section 86 reorganization is the right move, and whether it is safe, turns on a short list of facts about your company rather than on the provision itself:

• The gap between value and cost. Large accrued gains raise the stakes on valuation and make the freeze worth more; trivial gains rarely justify the fees.
• Where value must end up. Inside the same corporation, section 86 works; into a holding company or sister company, you are in section 85 and on the T2057 clock.
• Who receives the new shares. Family involvement brings TOSI and the benefit rule into the design; key employees bring their own share-terms questions.
• What sits on the horizon. A sale or succession inside five years argues for building the exemption tests and the buyer's clean structure into the same plan.
• The state of your records. The exchange is built on accurate adjusted cost base and paid-up capital figures; if the minute book and the T2 schedules disagree, that gets fixed first.

The work itself is a defined-scope project: a valuation you can defend, a written step plan naming each move and the provision behind it, articles and resolutions drafted by your lawyer to match, any elections filed on time, and closing entries that land the new structure in the books and the minute book identically.
