Ottawa Wants Founders to Keep 96% of a $15M Exit. Will It Keep Them in Canada?

Picture two founders who each sell a startup for a $15 million gain. One lives in Toronto, the other in New York. Until Thursday, the Toronto founder walked away with about 71 cents of every dollar while the New Yorker kept all of it. Ottawa wants to close most of that gap, and it is betting a lot of tax revenue that the gap is why builders keep leaving.

The 2026 federal budget introduces what it calls the Canada Growth Incentive, a two-part tax measure aimed at founders, early employees and the investors who back them. Keep one thing in mind before you start planning your exit party. These are budget proposals, and they still need legislation to become law.

What exactly is on the table?

The headline piece is a new exemption on up to $15 million in capital gains from selling qualifying shares of an eligible Canadian company. The budget says a founder with a $15 million gain would keep "nearly 96%" of the value at exit, compared with 71% before. Its own chart puts an Ontario founder at 96.0% after the change, ahead of California at 86.8% and just behind New York at 100%.

The second piece stretches the small business rollover. According to the budget's tax measures annex, people who sell eligible small business shares would get the year of the sale plus three more calendar years to reinvest the proceeds and defer the tax. If you sign a SAFE (a simple agreement for future equity) with another startup inside that window, the deferral can stretch to five years.

Finance Canada pegs the exemption at $565 million in lost revenue through 2030-31, with almost all of it landing in that final year. The rollover adds $150 million over five years. The same budget also proposes expanding the SR&ED research tax credit to cover some commercialization costs, like regulatory approvals and patent protection, which it expects to cost $930 million over five years.

Who actually qualifies?

This is where founders need to read the fine print. The annex says the company must be a Canadian-controlled private corporation when the shares are issued, with combined assets of no more than $100 million. You must hold the shares for at least 36 months before selling. The shares must be issued for cash or in exchange for your work at the company, and the business has to operate primarily in Canada for at least 24 months after issuance.

Timing is the biggest catch. The exemption only covers shares issued on or after budget day and before 2037. As The Globe and Mail points out, that limits the benefit for founders who already launched their companies or investors with existing stakes.

Whole sectors are shut out, too. Consultancies, professional practices like law, accounting and medicine, and businesses in agriculture, fishing, forestry, mining, finance, insurance, utilities, real estate, food and accommodation, and arts, recreation or entertainment do not count. Franchises are out as well.

Will it stop the brain drain?

Industry groups certainly think it helps. The Council of Canadian Innovators, the Canadian Venture Capital & Private Equity Association and the National Angel Capital Organization lobbied for this through a campaign called "Bet on Canada," according to BetaKit. CCI chief executive Patrick Searle told the Globe he welcomed the "focus on channelling the success of one entrepreneur into the success of more entrepreneurs in Canada." CVCA chief executive Benjamin Bergen said Ottawa is "rewarding investors who put capital into Canadian companies and stay with them as they grow."

Finance Minister François-Philippe Champagne put it more bluntly. "We want more Shopifys," he said at a press conference, per BetaKit.

The model is the American Qualified Small Business Stock break, known as QSBS. The Globe reports the US version carries a similar US$15 million cap and is set to cost the US Treasury more than US$60 billion between 2025 and 2034. Silicon Valley investors have been big winners, and critics call it an unnecessary break for the wealthy.

Tax rates are only one reason founders leave, though. Capital is the other. A recent Panache Ventures report found that about one in eight Canadian tech startups created in 2023 secured pre-seed money, a share that dropped to one in 12 in 2024 and held there in 2025. A better exit does nothing for a company that never gets its first cheque. The rollover is the part aimed at that problem, since it nudges people who cash out to put their gains into the next round of Canadian startups.

Who gets most of the money?

Ottawa's own math answers this one. The budget's gender and diversity impacts annex rates the exemption "strongly regressive." It says the people who benefit directly tend to be men (over 75%), and nearly 84% would have adjusted gross income above $200,000.

That is the trade the government is making on purpose. It argues that a richer payoff at the top pulls more capital and talent into early-stage companies, which eventually creates jobs for everyone else. Whether that trickle actually happens is something you will only be able to measure years from now.

What should founders do right now?

Start with your cap table. Because eligibility depends on when shares are issued, anyone raising a round or granting equity in the coming months should talk to a tax lawyer about structuring it to qualify if the rules pass. Shares must be held directly by an individual or through a partnership, so how you hold them matters.

Check your sector. If your startup sits in a gray zone, say a creative studio, a food brand or a services-heavy agency, confirm early whether you fall into an excluded category.

Watch the integrity rules. Finance says it will release more details later to stop people from multiplying the $15 million limit across several companies running the same business.

Plan for the long game. With a 36-month holding period and benefits that mostly start showing up in Ottawa's books in 2030-31, this is a reward for people who build for years. For a generation of founders who were told to move south to make real money, it is the strongest signal yet that staying might finally pay.
