Canada’s federal budget, tabled this week, introduces a new tax break called the Canada Growth Incentive: a capital gains exemption of up to $15 million on the sale of qualifying shares in eligible businesses, according to the Department of Finance Canada’s Budget 2026 backgrounder. The measure is paired with an enhanced small business rollover, which lets founders defer tax further by reinvesting proceeds into another qualifying business.
The exemption applies to qualifying shares issued on or after budget day and disposed of before 2037, CBC News reported. The budget documents describe the $15-million threshold as “substantial,” noting that founders who qualify would keep close to 96% of their company’s value when they exit, rather than having roughly half of the gain taxed away under ordinary capital gains rules.
The measure is aimed at entrepreneurs, early employees holding equity, and investors in Canadian-resident companies — the government’s stated goal is to help “high-potential businesses attract investment, scale and keep more capital in Canada,” per the Finance Canada backgrounder. Conservative leader Pierre Poilievre criticized the broader budget package even while the capital gains measure drew notice from tax advisors as one of its more consequential provisions for founders and startup investors.
Tax professionals caution that not every shareholder will qualify. Eligibility turns on the type of shares, when they were issued, and whether the underlying business meets the “qualifying” test — details that will be set out in the implementing legislation rather than the backgrounder itself. Investors or founders who already hold shares issued before budget day should confirm with a tax advisor whether their specific holdings fall inside the window, since the exemption is prospective (shares issued on or after budget day) rather than retroactive.
For non-resident investors or dual-status individuals with ties to Canadian private companies, the exemption is a new variable to weigh alongside Canada’s existing lifetime capital gains exemption for small business shares, which this measure supplements rather than replaces.
