Selling Your Business in Ontario: Financial Planning Considerations

For most business owners, the sale of their business is the single largest financial transaction of their lifetime. It's also one of the most tax-sensitive. How you structure the deal, when you sell, and how prepared you are going in can mean the difference of hundreds of thousands — or even millions — of dollars in after-tax proceeds. Yet the majority of Ontario business owners begin thinking seriously about succession planning far too late.

If you're within five to ten years of a potential sale, or if you've had an unsolicited offer land in your inbox, now is the time to understand what you're working with.

The Lifetime Capital Gains Exemption (LCGE)

One of the most valuable tax provisions available to Canadian small business owners is the Lifetime Capital Gains Exemption (LCGE). In 2024, the LCGE for qualifying small business corporation (QSBC) shares was increased to $1.25 million. That means an eligible business owner can shelter up to $1.25 million in capital gains from the sale of qualifying shares — completely tax-free at the federal level (with corresponding provincial treatment in Ontario).

For a couple who each own shares in a qualifying corporation, that exemption can potentially be doubled. Family trusts can also be used in some structures to multiply the exemption across beneficiaries — though these strategies require careful legal and tax planning well in advance.

To qualify, the shares must meet specific criteria: the corporation must be a CCPC (Canadian-Controlled Private Corporation), at least 90% of the assets must be used in an active business at the time of sale, and shares must have been held for at least 24 months. Purification strategies — removing passive assets from the corporation before sale — are often needed to ensure eligibility. This is not something to arrange in the weeks before closing.

Asset Sale vs. Share Sale: The Buyer-Seller Tension

A recurring tension in business sales is whether the deal is structured as a share purchase or an asset purchase. Sellers generally prefer a share sale: it's simpler, and it allows access to the LCGE. Buyers often prefer an asset purchase: it gives them a stepped-up cost base on individual assets and limits assumption of the corporation's historical liabilities.

The structure of the deal affects your tax outcome significantly. In a share sale, the seller pays capital gains tax on the gain — which is taxed at preferential rates and may be offset by the LCGE. In an asset sale, proceeds flow through the corporation, potentially triggering corporate tax, and then again through your hands as dividends or salary — a much less efficient outcome for the seller.

Negotiations around deal structure are common and can be complex. Understanding your position before entering those negotiations is essential.

What Happens After the Sale?

Many business owners are so focused on the sale itself that they don't plan sufficiently for what comes next. If you sell your business for $2 million after tax, that capital is now sitting outside the structured environment of your corporation — and you suddenly need an investment strategy, a drawdown plan, and a tax-efficient income structure for retirement.

This is where working with a financial planner before the sale becomes especially valuable. What are your annual income needs? How much risk do you want to take with the sale proceeds? Do you need to generate income immediately or can proceeds remain invested? What does your estate look like after the transaction?

These aren't questions to answer after you've signed. They should inform how you negotiate the sale, how you time it, and how you set up the post-sale financial structure.

Planning Well in Advance

Effective business succession planning in Ontario typically starts three to five years before a target sale date. That's enough time to reorganize share structures, purify the corporation for LCGE eligibility, bring in family members where appropriate, and build a post-sale financial plan.

Marc Pineault at Pineault Wealth Management works with business owners in London, Ontario and across southwestern Ontario who are thinking about eventual succession — whether that's a sale to a third party, a transition to family, or a management buyout. If a sale is anywhere on your horizon, starting the planning conversation now is always better than scrambling when a buyer appears.
