Biggest Online Casinos

Online gaming has come a long way since its inception in the 90s. To date, online gambling hubs remain on the wave, going toe to toe with land-based giants like Las Vegas.

What elevates online casinos higher than brick-and-mortar outlets is the element of convenience and higher payouts.

The idea of making millions on-the-move is irresistible, so more bettors are looking to join the latest trend in gaming. However, with the thrill of online gaming comes the risk of cyber-crime and threats.

For this reason, the biggest online gambling sites prove to be a safer option.

Not only do they boast impeccable reputation, but they bring numerous other benefits that you wouldn’t get from brick-and-mortar or smaller online casinos.

A trait shared by the industry bigwigs, you’ll find a cluster of notable slot machines, well-balanced with an incredible assortment of table games.

Big enterprises support mainstream suppliers like NetEnt and sprouting free programming engineers like StormCraft Studios.

For bettors, this mirrors an opportunity to explore a wide selection of titles, more than enough to make a big win.

Moreover, by cherry-picking a large casino, you automatically qualify for the front-seat to brand-new games in the market.

To sweeten the deal, you’ll also find a devoted live casino that strongly contends with the legendary Vegas.

While small enterprises may struggle to provide a lucrative with no deposit bonus to boost your first-play, big casinos can afford to award free spins, and sometimes, cold hard cash.

This means that slot fanatics and live casino thrill-seekers can relish fantastic casino bonuses, free spins, cashbacks, and no deposit bonuses on their favourite games.

If you’re a veteran in the online gaming atmosphere, the concept ‘Big Casino, Big Payout’ should ring a bell.

Large enterprises are well-known for their ‘go big or go home’ slogan, hence offer a wide selection of progressive jackpot slots with life-changing payouts.

To keep up with their reputation, the big names take pride in providing record-breaking jackpots. Take advantage of this ploy, and check out their progressive title. You might just win yourself millions!

With a wealthy lobby also comes the possibility of technical glitches. To ensure a flawless gaming experience, the biggest online casinos protect their reputation to their support mechanics.

While smaller enterprises offer either of these mechanics, key players have a 24/7 Live Chat, telephone number, an online form, an email address, and sometimes, a postal address for the select few that favour the traditional pen to paper method.

Most importantly, bigwigs recognize the danger that comes with a loaded lobby. To curb the issue of gambling addiction, a section is usually dedicated to Responsible Gaming.

How do you rank casinos here?

You’re probably wondering how we came up with our esteemed list of the biggest online casinos in Canada. A gaming site doesn’t automatically become the biggest online casino in the world by default.

A whole list of factors comes into play that incidentally separates the big dogs from the up-and-coming gaming operators.

To come up with our list, we investigate the casinos’ full offering by taking a holistic look at aspects such as the gaming platform’s legitimacy.

Before you can even nitpick other service areas of online casinos, it’s important to investigate whether the gaming platforms have a legal foot to stand on.

All online casinos that make our list are licensed and registered by reputable authorities in the gaming world. Here we are talking about the likes of the formidable UK Gambling Commission and the Malta Gaming Authority.

After we confirm an online casino’s legitimacy, we zero in on factors such as the signup bonuses on offer.

It’s no secret that for most Canadian bettors to even give any gaming site as much as a second look, it must offer a welcome bonus package worth the attention.

Most of the biggest online casinos in Canada boast a large financial pool, which means they can afford to splurge when it comes to creating an elaborate welcome bonus.

This in turn separates large online casinos from small gaming sites offering mediocre signup packages. All casinos on our list offer generous welcome packages to pique gamers’ interests.

But they don’t stop there. You have to realize that it’s fairly easy for an online casino to offer a mind-blowing welcome bonus only to attach steep wagering conditions to it that some bettors find impossible to meet.

When this happens, bettors simply close their accounts and jump ship. Again, that’s where large online casinos have an unmatched advantage.

Because of their somewhat large financial resources, they can afford to offer bettors reasonable and low wagering conditions allowing them to maximize gameplay.

Other bonus terms to look out for include the minimum deposit amounts. As you know, gamers usually need to deposit a certain amount to activate the welcome bonus.

Large online casinos usually offer low minimum deposits, which work to the advantage of the gamers.

Other factors that we look at include the online casinos’ customer support. A gaming platform backed by a responsive and professional customer service team is always a winner.

If they can offer round-the-clock support, that’d be even better.

Then we look at the payment methods available. Is the casino offering players fair and reputable payment methods characterized by quick deposit and withdrawal timeframes and reasonable limits?

Finally, the gaming interface also comes under scrutiny. No matter how elaborate an online casino’s games lobby is, it falls flat if players have a hard time navigating the site.

While all these factors come into play, we particularly check out the main part of the casino, which is the game catalogue, as follows:

Table games

There are standard table games Canadian gamers expect to see when they sign up with casinos that claim to be the largest.

Few bettors will stick around if the gaming site’s table games library doesn’t offer classic card games like the iconic Blackjack, the popular Roulette, and fascinating Baccarat.

Even so, having these table game categories is only the first step. Large online casinos usually go all out to offer bettors multiple variants of their favourite table games.

Though table games fall into different categories, some have slight variations regarding rules and gameplay.

The mark of a well-established and large online casino is the ability to pick and choose their preferred variant depending on the rules they are most familiar with.

For instance, when we talk of Blackjack, apart from the classic version, variations like Multihand blackjack need to be part of the action.

Craps, Sic Bo, and Poker games also fall under this section, with titles like Caribbean Stud and Texas Hold’em usually part of the lineup.

Bear in mind that aside from regular casino games, large online casinos also offer computer-generated table games, as in live games, complete with real live professional dealers.

Live casino

Bettors need not necessarily step out of their houses to enjoy a live casino gaming experience. Most online casinos make it a point to provide players with a dedicated live casino game section.

But it’s the magnitude of live casino games on offer that qualify gaming platforms to be ranked among the biggest online casinos on the gaming scene.

As mentioned, table games mostly fall under this bracket where players can log into the respective virtual studios of different titles like Live Blackjack, Live Baccarat, and Live Monopoly.

But there are a sizable number of other casino games that large casinos rope in as part of the live games studio.

Game shows such as Deal or No Deal, Gonzo’s Treasure Hunt, and Mega Wheel are just a snippet of titles that usually feature under the section.

Best believe, large online casinos adopt a go big or go home approach by including most of the notable titles to not only lure but retain gamers.

While the game selection is crucial, we check if the games are streamed in high quality characterized by HD graphics and realistic casino audio effects.

Also, the games need to be compatible with multiple smart devices for mobile gaming convenience.


The biggest online casinos don’t skimp when it comes to online slots selection.

As you’re probably aware, slots are the real moneymakers for most gaming sites and where most Canadian bettors are drawn to.

It follows that online gaming sites on our list give small gaming sites a run for their money by offering a wide slots selection.

However, it’s one thing having a wide selection of slots titles but of poor quality. Large and reputable online casinos don’t compromise on both quantity and quality.

As such, we look at the game providers behind the slots selection. You’ll find most gaming sites that make our list offering high-quality slots from some of the leading software developers in the iGaming world like NetEnt, Playtech, and Microgaming.

With regards to quantity, we check if the online casino offers different types of slots that appeal to gamers of varying interests and preferences.

As such, we ascertain if the slots offering includes classics, the likes of Book of Ra and Immortal Romance.

Also, we establish if the casinos offer progressive jackpot slots like Mega Moolah, a fan favourite known to offer bettors the possibility of landing big wins.

Other games

While table games and slots are usually the main attraction with most online casinos, bettors expect to see other popular casino games to feed their gaming frenzy.

Large online casinos use their resources and reputation to clinch chart toppers to keep gamers entertained for hours. Few bettors can say no to an impressive lineup of high-quality instant win games.

Such games are perfect for players looking for the thrill and excitement of online gaming minus the tension build-up. Moreover, instant win games don’t require much skill or strategy, making them fun and light-hearted.

In some cases, instant games allow players to win big money! Large online casinos try to cater to gamers of varying preferences by including such games, for example, scratch cards, dice throwing games, or other smaller but popular casino games.

We also check if the online casino in question offers such games for free. This option works better for players still starting in the gaming world and trying to get a feel of how instant games work.

Instead of depositing money, players can play these games using coins or credits for free, although they are usually limited in number.

Benefits of large casinos

So, what advantages do large online casinos offer when compared to their smaller counterparts? In other words, does larger necessarily mean better?

One thing is for certain, large casinos have a wealth of resources in their corner. As mentioned, a large financial pool means players can expect generous welcome bonuses associated with low wagering conditions.

Large casinos can also afford to run several exciting and rewarding promotions and tournaments at any given time, which small casinos may not be ready to.

They can afford to offer zero deposit bonuses to players where gamers get to play real money games and potentially win real cash without making a single deposit.

Also, big casinos can afford to tailor reload bonuses and other promotions to keep players entertained.

To add to the attractive signup packages, large online casinos have the resources to reward loyal players by creating plush VIP programs.

With such programs, players receive different rewards depending on their VIP levels which can include anything from loyalty points, dedicated personal account managers, cash rewards, and free spins.

As highlighted earlier, an extensive games lobby is synonymous with a large casino. After being wooed by the generous welcome packages, Canadian players are spoilt for choice when it comes to game selection.

The games lobby of a large casino will mainly consist of an incredible selection of high-quality games from leading software developers using the latest technology.

And most of the games offer huge payouts. To take it a step further, large online casinos have the resources to design high-quality websites for easy navigation by making use of the necessary filters.

You’ll find games neatly categorized based on software providers, alphabetically, popularity, category, and features.

Another benefit of large casinos is that there are fewer restrictions in terms of betting sizes and minimum/maximum wagering stakes.

Big casinos can afford to offer low minimum deposits and high maximum withdrawals. Still, on the financial aspect, big online casinos can use their influence and presence to partner with reputable payment platforms.

Canadian players can expect to see a long lineup of familiar, trusted, and credible payment processing services like Interac, iDebit, INSTADEBIT, and Paysafecard.

In essence, that means Canadian players have the liberty to choose their preferred payment platform from the available list depending on factors like payment timeframes.

Also, large online casinos can afford to employ the latest security features to keep players’ sensitive data private and secure.


No doubt, you’ll find countless gaming sites claiming to be the biggest online casinos on the iGaming scene. Thanks to our expert research, only the best of the best end up in this casino list.

All casinos that make our list go through an intense and thorough screening process by zeroing in on key factors highlighted earlier to give you a high-quality review.
