A search for best paying casinos Ontario might suggest that players are looking for the promise of a big win that will instantly change their lives for the better. But this isn't always the case. Some players are looking for high paying casinos based on payout rates, some want to find high RTP slots or the largest progressive jackpots, and some want to find sites that have already paid out big wins.

In Ontario, there are strict regulations that must be followed by all operators and choosing a high paying casino means you need to know what you're looking for. It's not just progressive jackpots, although Mega Moolah has the record for the highest payout in Canada, with a C$20 million payout in 2019.

There's also the payout percentages (very important), the payment methods, and of course, the maximum cashout limits. There's nothing worse than winning a jackpot and having it paid out in dribs and drabs.

When the AGCO opened up the market in Ontario, it led to an influx of operators looking to make a profit. The move brought some of the best paying casinos to Ontario and some that don't pay so well.

There are still casinos that operate illegally, and a recent study by IPSOS found that illegal gambling attracted over 20% of the market share in 2024 (we believe this number is much higher)[1]. Playing on illegal sites is risky, as the AGCO can clamp down on them at any time, causing losses for members.

We recommend steering clear of unlicensed sites and only playing at one of the 87 regulated by iGaming Ontario[2]. To help you out, this page features the best paying casinos in Ontario.

What We Mean By The Best Paying Online Casinos in Ontario?

It may be hard to define exactly what "best paying" means when it comes to online casinos, as it can signal something different for every player. Sometimes it can refer to payout rates, jackpot size, historical wins, RTP rates, and withdrawal limits, among other factors. But don't worry, we have everything covered on this page.

Top 10 Highest Paying Casino Sites (Ontario Residents Only)

To make it easy for you to find the best paying casinos in Ontario, we've put together a list of our favourites.

What Do We Mean by Casino Payout Percentages?

The casino payout rate is a long-term calculation that gives an overall expectation of the amount of money a casino gives back on games played. The payout rate is expressed as a percentage, and it is not a guarantee of winnings. The payout rates are published by each casino and audited in regulated markets like Ontario.

Understanding the payout percentages will help you find a site to play at like Magic Red which has a payout percentage of 98.86% which is great.

How Does the Payout Percentage Differ From the RTP and House Edge?

The terms payout percentage and Return to Player (RTP) are often used interchangeably. Each game has its own RTP, while the casino percentage payout takes into account wagers and winnings across all games played.

The house edge is the mathematical advantage the casino has over players. It is the percentage of each bet that the casino expects to keep.

If we take 888 Casino with its 97.52% payout percentage, it means that for every $100 wagered, $97.52 is paid back to players and the remaining $2.48 is profit for the casino. You do have to remember that this is theoretical and calculations are based on long term expectations.

Play These 10 Games at Online Casinos if You Want the Highest Payouts

Not all games have the same average payout rate. Below we've listed 10 of the most popular games with high payout rates that you can play at the best paying casinos in Ontario.

Online Slots With The Highest RTPs

RTP can vary greatly, so we've put together a list of the top 10 slots with the highest RTP rates. You'll find these at a number of the online casinos in Ontario including Jackpot City, Spin, PlayOJO, and LeoVegas.

Progressive Jackpots - Massive Wins But Not The Best Paying Casino Game

Progressive Jackpots are always exciting to play. Each time you place a wager, a small portion of your stake is added to a central pot, which continues to grow until one player takes it all. Some players have taken home millions, but the RTP on these games is usually quite low.

Mega Moolah for example, is only 88.12% even though it's hugely popular, and the biggest Canadian payout was back in 2019 at Zodiac Casino for $20,057,734. It may offer millions but the big wins don't happen very often, so we don't recommend basing your choice of casino on progressive jackpots.

Bonuses at High Payout Casino in Ontario

Bonuses such as welcome offers, free spins, minimum deposit deals, and even no deposit bonus codes can be found at many of the online casinos in Ontario with high payouts. Unfortunately, you'll have to check the sites yourself as we can't divulge any information due to regulations on from the AGCO.

Player Beware: Watch Out For Predatory Terms, High Wagering, Min Withdrawals

Last Updated: Mon. Jul. 07, 2025

It might take a while to find the best payout casinos in Ontario and we recommend you do just that. You should take everything into account and check for publicly displayed payout rates. The Ontario casinos in our toplist all have their payout rates on display.

Another thing to be aware of is that some high payout casinos will promote and advertise generous bonuses, but prevent payouts due to high wagering requirements. It's very difficult to clear 200x wagering requirements which is the standard for the welcome bonus at Jackpot City, Spin, and any casinos within the Casino Rewards Group.

You might also find limits on win amounts (very common with no deposit or free spins bonuses), restrictions on games, and even limits on withdrawals.

Spin Casino has a minimum withdrawal limit of $50 which is quite frustrating if you're a low budget player or someone testing out a new site. With this limitation you have to wait until you've won over $50 before you can request a payout. A site like PlayOJO Ontario is a better option as there's no minimum withdrawal amount.

Sometimes these terms can be hidden in the fine print and players unknowingly forfeit their winnings. Always read the full terms and conditions.
