Gambling Age in Ontario: How Old Do You Have to Be to Gamble?
Reviewed by Ryan Caldwell, Casino Expert & Editor-in-Chief · Updated November 11, 2026
In Ontario the legal gambling age is 19 for casinos, online casino play and sports betting. Below you’ll find how old you have to be to gamble in Ontario for each type of play, the ID you’ll need at a casino and online, what it means if you’re 18, and how Ontario’s casino age stacks up against the rest of Canada.
All the casinos in the toplist accept only players who are 19 or older and physically in Ontario. Once you’re old enough, our main online casino Ontario guide shows how we compare them.
How Old Do You Have to Be to Gamble in Ontario?
Short answer: wondering how old to gamble in Ontario? You need to be 19 or older to gamble at a casino, play at a regulated online casino or bet on sports. Lottery tickets are the main exception at 18.
Like every Canadian province, Ontario sets its own gambling age. The rule covers land-based casinos and slot facilities, every website and app licensed through iGaming Ontario, OLG’s own online platform, and sports betting. At 18 you can buy lottery tickets in Ontario, but you can’t legally go onto a casino gaming floor or open a real money account at an Ontario online casino.
Ontario Gambling Age by Activity
Casino Age in Ontario: Entering a Land-Based Casino
The casino age Ontario sets is 19 at every venue, and that’s the legal age for casino entry in Ontario. So if you’re asking how old to go to casino in Ontario, it’s 19. Staff check ID at the door or on the floor, and anyone who can’t prove they’re 19+ is turned away or asked to leave. Some casino resorts let younger guests into restaurants, hotels or entertainment venues, but the gaming floor stays 19+ only. Our guide to Ontario casinos covers the main venues in the province.
Can You Go to the Casino at 18 in Ontario?
No. At 18 you can’t enter the gaming floor of an Ontario casino, even with an adult, and you can’t play slots or table games. People get this wrong a lot because 18 is the casino age in Quebec, Alberta and Manitoba. If you live near the Quebec border in Ottawa, keep in mind the rule depends on which side of the river you’re on. Heading to a casino in the GTA?

What ID Do You Need at an Ontario Casino?
Bring valid government-issued photo ID with your date of birth on it. Documents usually accepted include:
● An Ontario driver’s licence or a driver’s licence from another province.
● An Ontario Photo Card.
● A Canadian or foreign passport.
● Other government-issued photo ID with your date of birth, such as a permanent resident card.
Expired, damaged or photocopied documents are often turned down. If you look young, expect an ID check even if you’re well past 19, and keep your ID on you while you’re on the gaming floor.
Online Gambling Age in Ontario
Every regulated Ontario online casino has to confirm you’re 19 or older before you can play for real money. At sign-up you give your legal name, date of birth and address, and the casino verifies them, often electronically, sometimes by asking for photo ID and proof of address. Until that check is done, you can’t withdraw winnings. Our guide to legal online casinos in Ontario covers the other rules regulated sites have to follow.
1. You enter your legal name, date of birth and Ontario address at sign-up.
2. The casino checks your details against trusted data sources or asks for documents.
3. You may be asked for photo ID and proof of address before your first withdrawal.
4. Location checks confirm you are physically in Ontario before real money play.
5. Accounts found to belong to someone under 19 are closed, and winnings can be withheld.
At Ontario casinos, even demo or free-play modes can sit behind an age check. A site that lets anyone play for real money without verifying age isn’t operating under Ontario’s rules.
Sports Betting Age in Ontario
The sports betting age Ontario uses is 19 as well, the same legal betting age as for casino play. It applies to licensed online sportsbooks, sportsbook apps and OLG’s Proline, online and at retail outlets, with the same identity checks as online casinos. Our guide to sports betting in Ontario covers the regulated sportsbooks.
Lottery Age in Ontario
Lottery is the big exception to the 19+ rule. In Ontario you can buy OLG lottery tickets, draw games and instant tickets alike, from 18. Retailers may ask for ID, and a winner may need to prove their age before getting paid. Buying tickets for anyone under 18 isn’t allowed.
Gambling Age in Ontario vs Other Provinces
There’s no national gambling age in Canada, so the Ontario casino age of 19 doesn’t hold everywhere. Each province picks its own, and the answer changes when you cross a provincial line:
Online, what counts is where you physically are. An Ontario online casino account works for real money only while you’re in Ontario, and only if you’re 19 or older.
Keeping Gambling Away From Minors
Most underage online gambling happens on shared devices or through an adult’s account. If you play online, a few habits keep young people at home away from real money games:
✔ Never share your casino login, and do not let anyone else use your account.
✔ Turn off saved passwords and biometric login on shared phones, tablets and computers.
✔ Log out after every session.
✔ Use parental controls or content filters on children’s devices.
✔ Keep payment cards and banking apps secure.
✔ Talk openly with teenagers about the risks of gambling, including gambling-like features in games.
Responsible Gambling at Any Age
Turning 19 makes gambling legal. It doesn’t make it safe. Young adults are one of the groups most at risk of developing gambling problems, so set deposit and time limits from your first session and treat gambling as entertainment you pay for, never as a way to make money. If it stops being fun, Ontario’s BetGuard program lets you self-exclude from every regulated gaming site at once, and ConnexOntario offers free, confidential support 24/7.
