Canada's 2026 Budget Introduces Capital Gains Exemption and AI Infrastructure Targets

The 2026 federal budget proposes a new Canada Growth Incentive exempting the first $15 million in capital gains for eligible private business share sales, extends reinvestment rollover deadlines, expands SR&ED tax credits to commercialization costs, and targets 500 megawatts of new data centre capacity for AI development.

Canada’s 2026 federal budget introduces the Canada Growth Incentive, a tax measure that exempts the first $15 million in capital gains for founders, staff, and investors when they sell shares in certain private Canadian businesses. The incentive mirrors the U.S. Qualified Small Business Stock (QSBS) program, which carries a US$15-million cap.

Eligibility for the new exemption excludes professionals such as architects, lawyers, and doctors operating through professional corporations, as well as companies in the agriculture, forestry, mining, and insurance sectors. The measure applies only to shares issued from Thursday onwards, limiting benefits for existing founders and investors.

Finance Canada estimates the capital gains exemption will cost $565 million in tax revenue through the 2030–31 fiscal year. By comparison, the U.S. Treasury estimates its QSBS program will cost US$60 billion between 2025 and 2034.

The budget also extends the deadline for investors to roll proceeds from a company sale into another business from one year after the sale to three years. Ottawa estimates this rollover change will cost $150 million over the next five fiscal years.

Additionally, the government plans to expand the Scientific Research and Experimental Development (SR&ED) incentive to cover commercialization activities, including bringing products to market, regulatory approval, and patenting. Finance Canada expects the SR&ED expansion will cost $930 million over five years. Combined, the specified tax measures are estimated to reduce federal revenue by $1.645 billion.

On the infrastructure front, the budget sets a target of 500 megawatts of new data centre capacity to support artificial intelligence development and sovereign processing needs under the Canadian Sovereign Compute Strategy. This follows a previously pledged $2.04 billion in spending on a national AI strategy.

Groups including the Council of Canadian Innovators (CCI), the Canadian Venture Capital & Private Equity Association (CVCA), and the National Angel Capital Organization called for these changes in an open letter ahead of the budget.

Prime Minister Mark Carney’s Liberal government had promised a comprehensive tax overhaul during the 2025 election, but the 2026 budget sidestepped a broad overhaul in favor of these specific measures.
