Sports Interaction gets games before they're available anywhere else. Enjoy Pragmatic Play's Resurrecting Riches exclusively. You can, of course, find great betting options here as well.

  FireVegas - One of the best for tournaments

  FireVegas brings authentic Vegas-style online casino games to ON. Though FireVegas is relatively new, the casino offers a huge range of over 3,000 games, including 20 live dealer titles. The brand has become known for its 'Fire Tournaments' and regular competitions, offering more regular games to join than any other online casino. If you have a competitive streak, FireVegas is for you.

• 

  BetVictor Casino - One of the most trusted brands worldwide

  Founded in 1946, BetVictor is one of the world's longest-standing and best-known gambling brands. It joined the market after receiving a license in 2022 and operates legally across the globe. With 1,000+ games available it's not the biggest site. But you'll find titles from trusted brands like Pragmatic Play and Evolution. Plus, fans of the Raptors and other ON teams can quickly switch to sports betting via the all-in-one app.

  💬 User review: "I had the pleasure of speaking with Katherine and she was very quick to respond and provided me with excellent customer service. This site is definitely one of the best, highly recommend!" - Heather Thompson, Trustpilot review, May 7, 2025

• 

  Bally Casino - Best for well-known games

  Bally's not ballooned in size like other Ontario casinos launched in 2022, but it remains one of the best. Dive into 420+ slots, including top-of-the-line favourites like IGT's Cleopatra and Evolution's Starburst Galaxy. Plus, there are exclusive proprietary slots famously available offline, too. You'll also find tonnes of table games, including live casino versions. Signature Live Blackjack was the standout for me. Like at BetVictor, you can easily switch over to sports, too.

  💬 User review: "Payout is very fast. After putting $200 of my own money in I hit $10,000. They paid me out within 2 hours! Incredible! I’ve played on every other app as well and I have NEVER won anything like that before. They are a legit casino.” - L2766, App Store review, March 17, 2025

  🏅 Best features: Games from premium providers | Fast payouts via Interac and Visa | Switch to sports in one tap

Find my perfect casino

With 30 years of casino reviews behind us, Casino.org has honed the most comprehensive testing system in the industry. Our expert team completes a robust 25-step review process to determine the top online casinos Ontario offers. These steps cover everything from gameplay to support and security. Here's a snapshot of what makes the best Ontario online casinos stand out:

• Security and fairness

  Before we recommend a casino, we first test out its safety measures. No casino will make it to this page without holding proof of an iGO operating agreement (license). As part of getting their iGO approval, gambling sites must agree to deposit their Ontario-based revenue into the body's accounts.

  Beyond that, a casino like Jackpot City scores well because it also carries international licenses, uses SSL data encryption, and holds the Responsible Gambling Council's seal of approval. It could still get a higher score by getting audited by a third-party body like eCOGRA.

  
• Games and software

  We only recommend an online casino in Ontario with over 400 games. These will include a substantial range of slots, progressive jackpots, table games like blackjack and roulette, and live dealer options. Local gambling law requires casinos to have an overall payout rate of 85%. We like to see that average around 96% or more, though.

  The very best casinos will have well over 1,000 games, like BetMGM's 2,500+ strong lobby, all coming from top software providers. We like to see a minimum of 10 software developers on offer and look for reputable industry names like Microgaming, NetEnt, Relax Gaming, and more. Tooniebet scores very well here, with 38+ software types on its platform.

  
• Mobile play and apps

  The best online casinos must deliver an outstanding mobile experience, whether in-browser or on app. While several Ontario casinos online don't offer apps, examples like JackpotCity, which gets 4.3/5 and 4.5/5 ratings in the Play and App stores respectively, are our quality benchmark.

  As standard, every casino that we recommend will be available to play on mobile and optimized for iOS and Android device browsers. We guarantee that you'll also be able to find at least 90% of the desktop games available on mobile.

  Top marks will go to the mobile casinos with dedicated Ontario casino apps for players. This should be easy to use with a well-designed interface and search functionality. Plus, we always look out for app-specific features like exclusive games and more.

  
• Banking options

  At any top-rated online casino, real money players should expect a vast choice of local Canadian payment methods. The province's most used casino banking options are Interac, credit card, MuchBetter, and Paysafecard. Spin Casino scores highly here for offering all three among nine options in total. Many casinos provide around 6-8 options.

  Payout speeds must be fast, too, though these can vary depending on the payment method you choose. FireVegas and BetVictor score highest for processing some payments within 24 hours. That said, sites like BetMGM and Bally Casino still review well, with a 1-2 day payment window.

  
• Customer support

  We only recommend Ontario online casinos that put players first. This is why we always test the customer support channels before finalizing our rating.

  It's common for email to be the only contact option for players in ON, with FAQs for guidance. A site like Tooniebet scores most highly as it offers real-time support through live chat, email, and phone support. We give extra points to those sites that offer 24/7 service, and those that have actually useful FAQs.

You'll need to be aged 19 or above and present certain documentation to sign up with an Ontario casino online. Here's what's required to start playing for real money at any gambling site in the province:

• 

  What is the Ontario gambling age?

  You must be at least 19 years old to be able to place a bet or wager in any local casino. The same age restriction applies to those who wish to gamble at any Ontario online casino sites.

• 

  Do you need to be in Ontario to play?

  Yes, you must be physically located within province's borders to play at the regulated Ontario online casinos. If you are outside the province your account will be restricted. A casino is within its rights to refuse payout on any bets placed outside Ontario.

• 

  What proof of identity do you need to provide?

  To join an online casino in Ontario, you will also be asked for proof of identity. This can be your driver's licence, a current passport, or a Canadian Citizenship Card. The Ontario Photo Card may also be accepted for Ontarians who do not have any of the above.

• 

  Is online gambling taxed in Ontario?

  No, you normally won't pay tax on casino winnings. Under the Canadian government's Income Tax Act, money earned by winning on any form of gambling is not liable for taxation. The only exception is if you're a professional gambler who makes the majority of your income from wagering. You'll also have to pay tax on any interest you earn from investing your gambling winnings.

Joining a casino is a straightforward and quick process. Simply follow our step-by-step guide to start playing casino games in Toronto or elsewhere in the province today.

1Choose a casino and sign up

Choose one of our recommended Ontario casinos. To register, enter details like your address, date of birth, and mobile number. You will also need to verify your ID with a recent photo or live video and certain utility bills or legal documents.

---

2Make a deposit

Make your first deposit at the casino's banking section. This menu option may be called cashier, bank, or deposit. You'll need to meet any minimum deposit limit, and can choose from options like Visa, Mastercard, and Interac.

3Pick your game and play

Once you deposit, you're good to go! Browse the casino lobby to find your perfect game. Then, simply hit play and enjoy the fun.

You'll find a huge choice of casino games at every online casino Ontario has to offer. We've highlighted some of the most played games in the province below:

• 

  Slot games

  Online slots are almost always the most popular and common game at casinos online. Some of the most played online slots in Ontario, as tracked by PlayOJO and PowerPlay, are Big Bass Bonanza and Golden Macaque. The software behind these and other top slots titles includes Playtech, E-LITE, and Pragmatic Play.

  Big Bass Bonanza is a medium volatility game with an above average RTP of 96.71%. This gives you a better chance of a payout with less risky game results. Golden Macaque has a similar RTP of 96.73% but with higher volatility. It's popular with players willing to bet on riskier results for a bigger gain. There's a maximum win of 5,699x your stake.

  Editor's tip: You'll often see a slot's RTP and volatility noted in the casino lobby. While a higher RTP is generally always better (the casino takes less of a cut from winnings), volatility depends on the kind of bets you make. Low volatility means frequent and smaller win amounts, and high violatively means less frequent but larger wins.

  ⚖️ House edge: From 2% to 6%

• 

  Blackjack

  A low house edge makes online casino blackjack popular with players. In ON, Playtech's Premium Blackjack is one of the most played variants. It offers a higher chance of winning by limiting the decks to four and controlling some of the dealer's choices. You also have more options like doubling down on bets and splitting hands. This pushes the RTP up to a theoretical 99.67%.

  All Bets Blackjack is another top title from Playtech. It attracts more players as it's available in both standard and live versions. Payouts are also higher on the game, and an above average six side bets are available. Just be mindful that playing through basic strategy without the side bets offers the best house edge - 99.58%

  ⚖️ House edge: From 1.5%

• 

  Roulette

  Ontario's most popular online casino roulette games are Mega Fire Blaze and Quantum Roulette by Playtech. Mega Fire Blaze Roulette attracts more fans as it has both standard and live casino play. With a European roulette RTP of 97.31%, it has the edge with a bonus round payout of 10,000x your bet if the ball lands on a Fire Number. This is way above the 500x of other games.

  Quantum Roulette is popular with players who like a little more unpredictability in return for bigger wins. The gameplay matches European roulette, but five numbers are given multipliers from 50x to 500x. If the ball lands on one of these, any winning bets are multiplied. Just note that any winning straight-up bets have reduced payouts to fund the multipliers.

  ⚖️ House edge: From 1.5%

• 

  Video poker

  Playtech's Jacks or Better is the most played online video poker game in Ontario. As one of the best known variants, it's also attractive to players for a high 99.54% payout rate. You can also double or half double wins on your game if you're willing to risk a winning hand. Overall, you can win up to 4,000x your stake playing the game, so a bet of $2.00 would mean an $8,000 win.

  Deuces Wild Multi-Hand also receives the most bets in province-approved casinos. Playtech's multi hand function attracts players for the potentially larger wins. Playing five hands with each bet means any win is credited to each hand. Unusually, this feature is offered at the same payout rate as a single hand game, so there's no loss of winning funds.

  ⚖️ House edge: From 0.5% to 5%

• 

  Online poker

  Ontario is unique in Canada in offering regulated online poker rooms, which means it's the only province where you can find legal tournaments with fellow Ontarians.

  Texas Hold'em is the most popular variant as the simplest to learn. The faster pace also makes it the most visible game at online poker rooms and in televised tournaments. Because of this, it's far easier to find Hold'em games if you like to join Sit & Go and other tournaments.

  Omaha Hi is the next common variant in Ontario online poker. Players can enjoy a similar game to Hold'em that's fast played and quick to pick up. It has the advantage that you have more choice in the hand you play - as you receive four cards and discard two before laying.

  ⚖️ House edge: From 1.5%

• 

  Live casino games

  Casinos' live dealer games offer a virtual experience of playing in person downtown in Niagara Falls or Windsor. You can expect to see live versions of roulette, blackjack, poker, and baccarat, as well as gameshows. The most popular live casino games in Ontario are currently the live versions of Premier Blackjack and Quantum Roulette detailed above.

  Other top titles include Unlimited Blackjack and Live American Roulette, both from Playtech. Live Unlimited Blackjack has no cap on the number of 'seats' at the table, so you never have to wait to join a game. Unique game bets include instant wins on Dealer's Pair or Player Pair, and 21+3 side bets (where you bet that the player hand plus the dealer's card will add up to a poker hand).

  ⚖️ House edge: Depends on the game

Ontario has 29 AGCO-approved local gambling venues. These are around Toronto, Ottawa, Niagara Falls, Windsor, and other cities in the south of the province. These gambling clubs come with well-designed gaming floors plus excellent bars, restaurants, hotels, and other facilities, making for a great night out in some popular locations.
