Major Capital Gains Tax U-Turn: What Ontario Businesses Need to Know – March 2026
Major Capital Gains Tax U-Turn: What Ontario Businesses Need to Know – March 2026
By Bader A. Chowdry, CPA, CA, LPA | Insight Accounting CPA
In a significant policy reversal, the Canada Revenue Agency (CRA) has officially cancelled the proposed increase to the capital gains inclusion rate that was set to take effect in 2026. For business owners across Mississauga, the Greater Toronto Area, and Ontario, this represents a major shift in tax planning strategy — one that demands immediate attention and potentially a complete recalibration of your business succession and investment plans.
The cancelled proposal would have increased the capital gains inclusion rate from 50% to 66.67% on gains exceeding $250,000 annually for individuals, and on all capital gains for corporations and most trusts. That increase is now off the table, keeping the current 50% inclusion rate in place for all capital gains.
What This Means for Your Business
If you’re a business owner in Ontario who was rushing to sell assets, trigger capital gains before the deadline, or accelerate your succession plan to avoid the proposed tax hike, you can pause. The tax landscape has shifted back in your favor.
For small business owners and entrepreneurs:
- Selling your business: You no longer face the threat of a higher tax bill on gains above $250,000. Whether you’re selling to a third party, family members, or considering a worker cooperative transition, the tax treatment remains at the current 50% inclusion rate.
- Investment portfolios: Corporations holding investment assets can breathe easier. The proposed blanket increase on all corporate capital gains has been scrapped, preserving the current 50% rate.
- Real estate and asset sales: Commercial property sales, equipment dispositions, and other capital transactions will continue under existing rules, providing stability for planning.
What hasn’t changed — and what has improved: While the capital gains inclusion rate increase is cancelled, several positive changes are moving forward:
- Lifetime Capital Gains Exemption (LCGE): The LCGE for eligible small business shares and farming/fishing property increased to $1.25 million effective June 25, 2024, and will now be indexed to inflation starting in 2026. This is a significant win for business owners planning succession or exit strategies.
- SR&ED Program Expansion: The annual expenditure limit for the enhanced 35% Scientific Research and Experimental Development (SR&ED) credit has jumped from $3 million to $4.5 million, with taxable capital phase-out thresholds rising from $10–15 million to $50–75 million. If your Ontario business invests in R&D or innovation, you now have access to substantially more refundable tax credits.
- New $10 million exemption: A new capital gains exemption has been introduced for qualifying business sales to worker cooperatives, alongside technical adjustments for Employee Ownership Trust (EOT) sales.
Key Details & Numbers
Let’s break down the numbers with a practical example relevant to Mississauga and GTA business owners:
Scenario: You sell your incorporated professional services firm for a $500,000 capital gain.
| Tax Treatment | Under Cancelled Proposal | Current (2026 Reality) |
|---|---|---|
| Capital Gain | $500,000 | $500,000 |
| First $250k @ 50% | $125,000 taxable | $250,000 taxable |
| Remaining $250k inclusion | 66.67% = $166,675 | 50% = $125,000 |
| Total Taxable Income | $291,675 | $250,000 |
| Tax Savings (at ~50% marginal rate) | — | ~$20,837 |
That’s real money staying in your pocket — capital you can reinvest, use for retirement planning, or deploy into your next venture.
Additional context from the CRA and federal updates for 2026:
- Federal income tax brackets have been indexed upward by 2% to reflect inflation
- The lowest federal marginal tax rate dropped from 15% to 14%, effective for the full 2026 tax year
- TFSA contribution limit for 2026: $7,500
- EI maximum insurable earnings: $68,900 (up from $65,700)
- CPP first ceiling: $74,600; second ceiling: $85,000
What You Should Do Now
Don’t assume this reversal means you can simply ignore your tax planning. Here’s your action checklist:
- Review your 2026 tax strategy: If you accelerated asset sales or business succession plans to beat the proposed deadline, reassess whether those moves still make sense. In some cases, you may want to defer transactions to optimize timing.
- Maximize the LCGE: With the exemption now at $1.25 million and indexed to inflation, ensure your shares qualify as eligible small business corporation shares. This requires planning — ideally 24+ months before sale.
- Explore SR&ED opportunities: If your business develops new products, processes, or technologies, the expanded SR&ED program could deliver significant cash refunds. Many Ontario businesses leave this money on the table.
- Document everything: The CRA’s compliance focus hasn’t changed. Whether you’re claiming the LCGE, SR&ED credits, or navigating complex capital transactions, documentation is critical.
- Consider worker cooperative or EOT sales: The new $10 million exemption for sales to worker cooperatives is a game-changer for business owners without family succession plans. This option preserves your business legacy while maximizing tax efficiency.
- Update your corporate minute book: Capital gains planning often requires corporate reorganizations, share freezes, or estate freezes. These strategies require proper legal documentation and board resolutions.

Frequently Asked Questions
Q: Does the cancellation of the capital gains inclusion rate increase apply to all past transactions?
A: Yes. The proposed increase never took effect, so all capital gains continue to be taxed at the 50% inclusion rate. If you triggered gains in late 2024 or 2025 to avoid the proposed increase, those gains are still subject to the 50% rate — but you may have lost the flexibility of timing.
Q: Can I still claim the Canadian Entrepreneurs’ Incentive (CEI)?
A: The status of the CEI is currently uncertain following the cancellation of the general capital gains inclusion rate increase. The CEI was designed to reduce the inclusion rate to 33.33% on up to $2 million in eligible capital gains for qualifying entrepreneurs. Consult with a CPA to understand how this policy change affects your specific situation.
Q: How do I know if my business shares qualify for the Lifetime Capital Gains Exemption?
A: Qualifying shares must meet specific criteria: the corporation must be a Canadian-controlled private corporation (CCPC), more than 50% of assets must be used in an active business carried on primarily in Canada, and you must have held the shares for at least 24 months. There are additional tests related to asset composition and use. Our team at Insight Accounting can perform a detailed LCGE qualification review for your corporation.
The Bottom Line
The CRA’s cancellation of the proposed capital gains inclusion rate increase is a rare piece of good news in the tax world. For Ontario business owners, it represents preserved flexibility, lower tax bills on significant transactions, and breathing room to plan succession strategies without artificial deadlines.
But good tax planning isn’t reactive — it’s proactive. The businesses that thrive are the ones that anticipate changes, optimize timing, and work with experienced advisors who understand both the rules and the opportunities.
Whether you’re planning to sell your business in the next year or the next decade, now is the time to get your tax house in order. The LCGE increase, SR&ED expansion, and new worker cooperative exemption create powerful planning opportunities — but only if you take action.
