Gambling Age in Ontario: How Old Do You Have to Be to Gamble?
Reviewed by Ryan Caldwell, Casino Expert & Editor-in-Chief · Updated November 10, 2026
The legal gambling age in Ontario is 19 for casinos, online casino play and sports betting. This guide answers how old you have to be to gamble in Ontario for every type of play, explains the ID you need at a casino and online, covers what happens if you are 18, and shows how Ontario’s casino age compares with the rest of Canada.
Every casino in the toplist requires players to be 19 or older and physically in Ontario. Our main online casino Ontario guide covers how we compare casinos once you are old enough to play.
How Old Do You Have to Be to Gamble in Ontario?
Short answer: if you are wondering how old to gamble in Ontario, the answer is 19 or older to gamble at a casino, play at a regulated online casino or bet on sports. Lottery tickets are the main exception, with a minimum age of 18.
Ontario sets its gambling age provincially, as each Canadian province does. 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. If you are 18, you can buy lottery tickets in Ontario but cannot legally enter 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, and it applies at every venue: that is the legal age for casino entry in Ontario. So if you’re asking how old to go to casino in Ontario, the answer is 19. Staff check ID at the entrance or on the gaming floor, and anyone who can’t prove they are 19 or older is refused entry or asked to leave. Some casino resorts have restaurants, hotels or entertainment venues open to younger guests, but the gaming floor itself is 19+ only. Our guide to Ontario casinos covers the province’s main venues.
Can You Go to the Casino at 18 in Ontario?
No. You cannot enter the gaming floor of an Ontario casino at 18, even with an adult, and you cannot play slots or table games. This is a common point of confusion because 18 is the casino age in Quebec, Alberta and Manitoba. If you live near the Quebec border in Ottawa, remember the rule changes depending on which side of the river you are on. If you are visiting a casino in the GTA, see our guide to Toronto casinos and the other land-based guides in the card grid below.
What ID Do You Need at an Ontario Casino?
Bring valid, government-issued photo ID that shows your date of birth. Commonly accepted documents 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 refused. If you look young, expect to be asked for ID even if you are well over 19, and keep it with you while you are on the gaming floor.
Online Gambling Age in Ontario
Every regulated Ontario online casino must confirm that you are 19 or older before you can play for real money. When you register, you enter your legal name, date of birth and address, and the casino verifies them — often electronically, sometimes by asking you to upload photo ID and proof of address. You cannot withdraw winnings until this check is complete. Our guide to legal online casinos in Ontario explains the rest of the rules regulated sites must 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.
Demo or free-play modes may also sit behind an age check at Ontario casinos. Sites that let anyone play for real money without verifying age are not operating under Ontario’s rules.
Sports Betting Age in Ontario
The sports betting age Ontario uses is also 19 — the same legal betting age as for casino play. That applies to licensed online sportsbooks, sportsbook apps and OLG’s Proline, both online and at retail outlets. The same identity checks apply as for online casinos. Our guide to sports betting in Ontario covers the regulated sportsbooks.
Lottery Age in Ontario
Lottery is the main exception to the 19+ rule: in Ontario you can buy OLG lottery tickets, both draw games and instant tickets, from age 18. Retailers can ask for ID, and a winner may have to prove their age before the prize is paid. Buying tickets for anyone under 18 is not allowed.
Gambling Age in Ontario vs Other Provinces
Canada has no single national gambling age, so the Ontario casino age of 19 does not apply everywhere. Each province sets its own, which is why the answer changes as you cross a provincial border:
For online play, the rule that matters is the one where you are physically located. An Ontario online casino account can only be used for real money while you are in Ontario, and only if you are 19 or older.
Keeping Gambling Away From Minors
Most underage online gambling happens on shared devices or with an adult’s account. If you play online, a few simple habits keep young people in your 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
Reaching 19 makes gambling legal, not risk-free. Young adults are among the groups most at risk of developing gambling problems, so set deposit and time limits from your first session and treat gambling as paid entertainment, never as income. If gambling 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.
