No. In Canada, lottery winnings are not taxable. The Canada Revenue Agency's Income Tax Folio S3-F9-C1 (paragraph 1.16) states that "the amount or value of a prize received by a taxpayer from a lottery scheme is not taxable as either a capital gain or income," and the CRA lists "lottery winnings of any amount" among the amounts that are not reported or taxed. A $5 million Lotto 6/49 jackpot is not income, so there is no income tax on it and nothing to report on your return.
That holds for every Lotto 6/49 draw on our statistics page (more than 4,400 of them) and every Lotto Max jackpot. It's a deliberate feature of how Canadian tax law defines income, not a loophole. But "the prize is tax-free" is only the headline. Tax does show up in three specific situations, and the rules change completely once a border is involved.
Why isn't a lottery prize taxed in Canada?
Canada taxes income from a source: employment, a business, or property. A lottery prize is none of those, so the CRA treats it as a windfall. The one exception the CRA names is a prize that can be considered "income from employment, a business or property, or a prize for achievement," which an ordinary lottery ticket isn't.
Because the prize isn't income, it doesn't go on your return and there's no tax on it.
What makes something a windfall?
The CRA doesn't decide case by case; it applies a consistent set of factors (paragraph 1.2 of the folio). A receipt looks like a non-taxable windfall when, among other things, the recipient:
- had no enforceable claim to the payment;
- made no organized effort to obtain it;
- did not seek or solicit it;
- had no expectation that it would recur; and
- did not receive it as a result of any activity or pursuit of gain.
A lottery ticket fits all of these. You can't demand a jackpot, no effort makes your numbers come up, and last week's result says nothing about next week's.
Don't confuse this with a prize for achievement, such as an award for achievement in a field the recipient normally works in. That falls under a different rule (paragraph 56(1)(n) of the Income Tax Act) and can be taxable. It has nothing to do with buying a lottery ticket.
When does tax show up? On what the money earns
This is the distinction that trips people up. The prize is tax-free. The money it becomes is not.
The exemption covers receiving the prize. Once you invest it, what it earns is ordinary investment income: interest on a GIC, dividends on shares, rent on a property, and capital gains when you sell at a profit. The CRA says so directly: "Income earned on any of the above amounts is taxable. For example, any interest that you earn when you invest lottery winnings must be reported on your return." For later tax purposes, paragraph 1.17 of the folio treats you as having acquired the prize at a cost equal to its fair market value when you received it.
In practice, this is where a large win meets the tax system. Year one: no tax on the prize. Every year after: tax on what the prize is earning. That's why it's worth talking to an accountant before you invest.
Can I give my winnings away tax-free?
Mostly, yes. The CRA lists "most gifts and inheritances" among the amounts a recipient doesn't report, and giving away cash doesn't create a tax on the gift itself. Gifting property other than cash (shares, a second home) is different: under section 69 of the Income Tax Act, a gift of property is treated as a sale at fair market value, so the giver can owe tax on any gain.
The catch is the attribution rules:
- Spouse or common-law partner. If you transfer money or property to your spouse, the income it earns is deemed to be yours (section 74.1(1)), and so are taxable capital gains when the property is sold (section 74.2).
- Minor children (and certain other relatives under 18). The income the gift earns is deemed to be yours until the child turns 18 (section 74.1(2)). Section 74.2's capital-gains rule covers spouses and common-law partners, not minors.
The gift itself isn't taxed; attribution only decides who pays tax on what it earns later.
What happens at death?
Canada has no separate inheritance tax, and the CRA lists most inheritances among amounts the recipient doesn't report. Instead, section 70(5) of the Income Tax Act treats you as having disposed of each of your capital properties at fair market value immediately before death, and any resulting gain is taxed on your final return. Section 70(6) lets property left to a surviving spouse (or a qualifying spousal trust) pass at its tax cost instead, deferring the gain until the spouse disposes of it. So an estate can owe tax on growth, never on the original prize.
What if a Canadian wins a US lottery?
The US taxes gambling winnings, lottery prizes included. The IRS says "gambling winnings are fully taxable," and gambling income includes "winnings from lotteries." This matters for Canadians who buy Powerball or Mega Millions tickets on trips south.
For a nonresident alien, which is what a Canadian is for US tax purposes, IRS Publication 519 says you are generally "subject to the 30% tax on the gross proceeds from gambling won in the United States," and the IRS's W-2G instructions say gambling winnings paid to a foreign person "are subject to 30% withholding." US residents are handled differently: payers withhold 24% when winnings minus the wager are more than $5,000.
On the Canadian side, the CRA's list of non-taxable amounts covers "lottery winnings of any amount" without distinguishing where the lottery was held. How a US win interacts with your Canadian return, and whether any part of the US tax can be recovered under the Canada–US tax treaty, depends on your circumstances, so ask a cross-border tax professional.
| Canada | United States | |
|---|---|---|
| Tax on the prize itself | None | Gambling winnings are fully taxable |
| Withheld when a resident claims | Not applicable: the prize isn't taxable | 24% when winnings minus the wager exceed $5,000 |
| Nonresident winner (e.g. a Canadian) | No tax on the prize | 30% on the gross proceeds |
Could gambling ever count as a business?
In theory, yes. The folio says profits from bookmaking or running a gambling establishment are business income (paragraph 1.11), and that an individual's gambling can be a business. But it also notes that the courts treat gambling, "even regular, frequent and systematic gambling," as "not generally regarded as a commercial activity except under very exceptional circumstances" (paragraph 1.13), such as someone applying inside information, knowledge and skill (paragraph 1.14). A lottery prize falls under paragraph 1.16 regardless: it is not taxable. If you bought a Quick Pick, none of this applies to you.
What this means for your ticket
- The prize is yours in full. No income tax on it, whether it's a Lotto 6/49, Lotto Max or Ontario 49 prize.
- Plan for the income, not the prize. The tax side of a big win is about what the money earns once invested.
- A US ticket is a US tax matter. Expect 30% to come off the gross prize.
- Claim it in time. Draw-game prizes expire one year after the draw; see how long you have to claim a lottery prize in Canada.
This isn't tax advice, and large estates and cross-border wins get complicated. But the foundation is simple and, for once, in the player's favour.
