Finances After Winning Money in Canada: Lottery Wins and Other Windfalls

A windfall (a lottery win, a large settlement, an inheritance, the sale of a business) creates decisions most people have never had to make. This page covers how the money and its earnings are taxed in Canada, the rules that apply when you share it with family, and what’s worth deciding before spending or investing it. It’s part of the financial planning hub; for money received from an estate specifically, see what to do when you receive an inheritance.

What’s taxed and what isn’t

So a lottery win, a gift or an inheritance generally arrives tax-free (a settlement for a lost job or the sale of a business can be taxable); tax starts once the money earns a return. For example, $100,000 earning 4% interest produces $4,000 a year of taxable income, and at a 43% marginal rate about $1,720 of that goes in tax. (Illustrative figures: $100,000 × 4% = $4,000; $4,000 × 43% = $1,720.)

Sheltering the income in registered accounts

Registered accounts let investment income grow without annual tax, up to each person’s room:

The FHSA is only for first-time buyers. You can open an FHSA if, when you open it, you are a resident of Canada, at least 18 (19 where that is the age to enter a contract) and no older than 71 on December 31 of that year, and a first-time home buyer: you didn't live, this year or in the previous 4 calendar years, in a home that you or your current spouse or common-law partner owned as your principal residence.

Check your available room on your CRA My Account or notice of assessment before contributing; how much TFSA room you have explains the TFSA calculation. Amounts beyond your room go in taxable accounts.

Sharing it with family: the attribution rules

The table is a summary. The rules in full:

• Income or loss from property you transfer or lend to your spouse or common-law partner (or someone who later becomes one) is taxed to you for the time you are resident in Canada and they are your spouse or partner.
• When your spouse or partner sells that property, you usually report the capital gain or loss, if at the time of the sale you are resident in Canada and still together.
• Income or loss from property you transfer or lend to a person under 18 who doesn't deal with you at arm's length (such as your child or grandchild), or to a niece or nephew under 18, is taxed to you for each year before the year they turn 18.
• Capital gains on property given to a minor are not attributed to you: the capital gains rule covers only a spouse or common-law partner.
• The rules don't apply to a loan that charges interest at least at the prescribed rate in effect when it was made (or a lower arm's-length rate), with each year's interest paid no later than 30 days after the end of the year (January 30); the prescribed rate for loans made in Q4 2026 is 3%.
• They don't apply to a transfer for consideration worth at least the property's fair market value (any debt in it charging interest as above, and for a spouse, with an election out of the tax-deferred rollover).
• While you and your spouse or partner live apart because the relationship broke down, income is not attributed, and capital gains are not if you both sign an election.

A documented loan at the CRA’s prescribed interest rate is the usual way to let a spouse earn investment income taxed at their own rate. A family trust can also split income or hold assets for the next generation, but it costs money to set up and run each year and needs legal and tax advice to structure.

Before spending or investing

People who’ve managed windfalls well tend to describe the same approach: slow down, keep the news to a small circle, park the money somewhere safe while deciding, and get advice from people who aren’t paid by what you buy.

• Somewhere safe to wait: a high-interest savings account or short GICs, bearing in mind that deposit insurance covers a limited amount per institution; see CDIC deposit insurance for what’s covered.
• Independent advice: a fee-only planner and a tax professional can map the tax and estate questions before anything is locked in.
• Debts: paying off high-interest debt is a guaranteed saving equal to the interest rate.
• Your estate: a large windfall is a reason to write or update a will and check beneficiary designations; see the estate planning hub.
