Online Slots in Ontario

Before the iGaming Ontario launch, gambling laws in the province only allowed players to access offshore casinos. With new regulations in place, though, the scene is now flourishing since local players can find Ontario-based casinos featuring a variety of new online slots.

Nevertheless, it’s still challenging to decide on the best online slots in Ontario, as new operators are registered almost daily, which, in turn, only leads to a growing number of new titles. Don’t worry, though — we’ll help you keep up with the latest trends and learn all about the legal background of Ontario slots, game types you can try, and relevant details that should help you choose the perfect slot for you.

Top 10 Online Slots Sites in Ontario

Legal Background of Ontario Slots

The selection of online slots available to Ontario players is dictated by iGaming Ontario. Whenever the organization grants its seal of approval to a new casino, its online slots become available to players.

Even though the software of each provider has not been inspected individually, there are some common patterns among the ones available on the approved websites. Here are the most important factors that iGaming Ontario considers when evaluating new casinos and slot games:

• Software fairness
• Fair and guaranteed payouts
• Integrity of slot providers and operators
• RNG and RTP metrics tested by iGaming Ontario labs
• Availability of responsible gambling features
• Clearly defined playing rules

With such regulations in place, players can rest assured knowing that websites they visit are legitimate and that they offer nothing but tried and tested games.

Popular Online Slot Providers in Ontario

Ontario casinos offer slot games from more than 50 renowned providers, a handful of which stand out by offering the majority of games Canadian players love. These include household names, such as Microgaming, Pragmatic Play, Push Gaming, Play’n GO, Relax Gaming, and Quickspin.

All these providers have several key traits in common — they offer slots with an average RTP close to 96% (industry standard) and are committed to promoting responsible and safe gambling.

Types of Ontario Slots in 2025

Luckily for players, Ontario-approved providers offer a variety of different types of slot games. The list includes bonus-buy slots, Megaways slots, and progressive games with prominent jackpot prizes, among others.

Bonus-Buy Slots

Bonus-buy games are currently among the most popular types of online slots in 2024, and you can play some of the top-rated games from this genre in Ontario. All of them offer a chance to purchase the bonus feature, usually for an amount worth 100x your base bet level.

Some games (like the ones by NoLimitCity) even offer two or three types of bonuses you can buy. However, keep in mind that each level comes with a distinctive volatility rate. As a result, you may have to pay a higher price to activate the bonus.

Megaways Slots

The famous Megaways slot mechanic was developed by Big Time Gaming. However, other providers like Pragmatic Play, Blueprint Gaming, and Play’n GO have also added it to their own titles under the licence from its original creator.

It’s a perfect feature to turn the excitement up a notch since the number of symbols on each reel changes with every spin. So, you can expect as many as 117,000+ ways to win depending on the game — naturally, the payout potential grows proportionally to this number.

Ontario players will be thrilled to hear that some of the most popular games from this genre can be found in the casinos available to them.

Progressive Slots

Progressive slots are arguably the most popular games among Ontario players — in fact, they are probably the most sought-after slot type in Canada since they come with growing jackpot prizes.

Sites approved by the iGaming Ontario launch, like Zodiac Casino, JackpotCity Casino, and Royal Vegas, all offer progressive slots with three jackpot levels — minor, major, and grand. You can even win millions on some games (like Mega Moolah or Treasure Nile). Here are some of the most popular jackpot releases available to Ontarians:

• Mega Moolah slot series
• Treasure Nile
• Major Millions
• Age of the Gods slots
• CashSplash
• Beach Life
• Gladiator
• Jackpot Giant

Most Popular Online Slots in Ontario

Ontario-based players enjoy playing slots from all of the categories outlined above. Mega Moolah is the most popular progressive jackpot slot available on the Ontario market — in fact, it’s the most beloved progressive slot in Canada overall.

The best thing is that you don’t even have to rely on the jackpot feature since a free spin bonus round with a 3x win multiplier could lead to lucrative wins during the base gameplay. Plus, there’s a lot of winning potential, thanks to 25 paylines and a 5×3 grid with wild symbols.

When it comes to bonus-buy games, Gates of Olympus is probably the most commonly played one on Ontario gambling sites. Unlike Mega Moolah, this one doesn’t have a progressive jackpot, but it holds up as one of the most well-known releases due to its 5,000x max win potential and a multiplier feature. During the bonus game, all the multipliers that land on the grid are kept in play for the following spins. They all add up to the overall win multiplier, allowing for large hits.

Another game with a multiplier is Reactoonz. This unique release comes with 5 stages of in-game bonus features, including Gargantoons, which fills the grid with random matching symbols. There’s also the multiplier feature and a wild, which are added to help form more winning combinations on active paylines.

Last but not least, we have the Wolf Gold slot by Pragmatic Play. Even though it’s relatively old, its relevance remains unaffected. This is largely due to the features like Colossal symbols, Hold & Win coins, and four jackpot levels, which give it a fresh and modern feel.

Some of the honorable mentions include:

• Big Bass Bonanza
• Buffalo Trail
• Sweet Bonanza
• Book of Oz
• Sugar Rush
• Mustang Gold
• Razor Shark
• 5 Lions Megaways
• Wild Wild Riches
• Temple Tumble
• Money Cart

What to Look for in Ontario Slots in 2025?

In case you want to find some interesting slots on your own, here are some of the criteria you should keep in mind.

RTP

The RTP stands for “return to player,” and it’s a ratio that determines the slot’s return over a large number of spins. It stands around 96% on average, and is a crucial factor in determining your risk level related to a specific slot.

In case you run across a game that boasts an RTP higher than this, you may have a better chance of landing some wins — still, keep in mind that this percentage only shows how likely the slot is to pay out in the long run.

Volatility

Slot volatility is a concept based on hit frequency. It is perfectly described by the old saying, “the greater the risk, the bigger the reward”. If you choose to play a highly volatile slot, chances are that the max win will be quite high as well; however, keep in mind that hit frequency is usually way lower. For instance, Hand of Anubis or The Money Train II offer max win rates worth up to 50,000x your bet size. Naturally, you may hit more dead spins along the way, but you’ll probably brush them aside in no time should you hit a massive win multiplier.

Besides high-volatility games, there are also low-volatility and medium-volatility ones. A perfect example of a low-volatility slot is the Starburst game by NetEnt. Here, you can expect more frequent “small” hits. By the same token, you can only win up to 500x your bet — as a result, bolder players may opt for some daring alternatives.

In-Game Features

Nowadays, players rarely settle for low-action slots — and truth be told, there’s nothing wrong with being picky and going for the games that come with both bonus rounds and in-game features.

These could range from jackpot prizes to in-game mechanics like Megaways or Hold & Win — or even in-game bonuses, as you can see from popular Ontario slots like Razor Shark or Wild Wild Riches.

Final Thoughts

Discussing Ontario slots, in general, is getting tougher by the day, particularly because the list of approved titles has been growing ever since 2020, when the iGaming industry was launched in this province.

Still, the games listed in this piece have all been vetted by our experienced team, so why not give them a spin? Make sure to only settle for top-quality options in terms of RTP, RNG, and in-game features — that way, your winning chances will increase, and you are bound to have heaps of fun!
