What favours insurance
No yearly tax on growth. In a corporate portfolio, investment income is taxed at about 50% in Québec in the year it is earned. Growth inside an exempt life insurance policy is not taxed as it builds.
No effect on the small business deduction. Above $50,000 of passive income a year, the corporation's business limit shrinks, and it is gone at $150,000. Growth in an exempt policy doesn't count, so the business keeps its lower rate.
A tax-free exit at death. The death benefit, less the policy's adjusted cost basis, is added to the capital dividend account and can be paid to your heirs tax-free. A portfolio faces corporate tax and then personal tax on dividends to get out.
What favours investments
Access to the money. A portfolio can be sold in days. In a policy, the cash value can be below the deposits for the first several years, and getting at it has a cost.
Flexibility. Investments can be reduced, stopped or redirected at any time. A policy is built to last decades, and the planned deposits have to be sustainable.
Insurability. Insurance requires medical underwriting. A health condition can raise the cost, limit the coverage or lead to a decline.
A goal in your lifetime. If the money is meant for retirement, buying a business or expanding within 10 to 15 years, investments fit better.
What it looks like at $1 million, $5 million and $10 million
A 47-year-old Québec owner, male, non-smoker, puts the same amount into the corporation every year for 10 years, then stops. On one side, a portfolio earning 6% a year inside the corporation. On the other, a corporate-owned participating whole life policy paid over 10 years. The table shows what reaches the family after tax, insurance first, portfolio second.
| Total deposited | Age 57, deposits end | Age 72 | Age 85 |
|---|---|---|---|
| $1M ($100,000 a year) | $1.78M vs $0.78M | $3.58M vs $1.77M | $6.32M vs $3.42M |
| $5M ($500,000 a year) | $8.94M vs $3.90M | $17.92M vs $8.84M | $31.67M vs $17.08M |
| $10M ($1M a year) | $17.89M vs $7.79M | $35.83M vs $17.67M | $63.33M vs $34.16M |
The results scale with the amount: $20 million gives twice the $10 million figures. To match the policy at 85, the portfolio would need to earn 6.7% a year if it were all deferred capital gains, 7.9% in realized gains, 10.0% in dividends or 12.3% in interest, every year for 38 years. The policy's after-tax return to that age is 5.62%.
The figures leave out the small business deduction. At $1 million the portfolio's passive income stays around $42,000 a year during the deposit years and passes $50,000 later as it grows. At $5 million it passes $150,000 within the deposit years, which removes the operating company's small business deduction entirely, up to about $71,500 a year of extra tax in Québec in 2026. For an owner whose business uses the deduction, the real gap is wider than the table shows.
The cash comes later. This design is built for the estate, not for cash in the early years. At $1 million, after 5 years $500,000 has gone in and the cash value is about $152,000; after 10 years, $1 million has gone in and the cash value is about $788,000. It passes the deposits in the 12th year. Money you may need sooner belongs in the portfolio.
If the insurer pays lower dividends. Dividends on a participating policy are not guaranteed. At $1 million, if the dividend scale ran 2 percentage points below today's for the life of the policy, the family would receive about $2.24 million at 72 instead of $3.58 million, still more than the portfolio's $1.77 million. At very old ages the picture changes: by 97, the portfolio would leave more than the policy under that lower scale.
Illustrative only, from participating whole life illustrations dated October 25, 2026, at the insurer's current dividend scale, which is not guaranteed. Corporate tax on investment income 50%, shareholder dividend tax 45%. The portfolio earns 6% a year, split across interest (30%), dividends (20%), realized capital gains (20%) and deferred capital gains (30%). Another example, at $3 million, is in this case study.
How to decide
Five questions settle most cases. How much of the surplus will you need in your lifetime? Over how many years? Does your health allow insurance at a reasonable cost? Do you want to leave a set amount to your family, or fund the tax at death? Does the corporation already have more than $150,000 of passive income, so the small business deduction is already gone?
The answer then shows on a written comparison of three options: investments only, insurance only, and a combination. Same deposits, same horizon, taxes and costs included, guaranteed values kept apart from projected ones. Your accountant gets the same document. That is how the work runs, as described in what to expect.
