Casumo Ontario Review 2025 - Is Casumo legal in Ontario?

On the Kambi sportsbook platform, Casumo is now also one of the available legal Ontario betting sites, which also offers casino gameplay from the same account. As a mobile-forward provider, they are a reasonably unique option available in Ontario. In general, we are positive about the Casumo sportsbook and casino offering. However, there is one caveat with Casumo that should be highlighted before moving ahead with the review, especially for sports bettors: 

You should only look to make a deposit if you are 100% sure that you will play your deposit fully, at least once through. For example, if you deposit $200, you'll have to make $200 in wagers, whether in the sportsbook, casino, or a mix, before you will be able to make a withdrawal.

As part of our review process, we look to deposit funds to then see how fast a given operator will process a withdrawal. When we did this at Casumo initially, they canceled our withdrawal, because we had not yet played the full amount of our deposit, once over.  Casumo's terms don't specify this explicitly, but they do have somewhat nebulous terms and conditions that talk about the level of play needing to match the deposit level before withdrawal will be allowed.

So be sure you're ready to play your deposit amount at least once through. If you're more of a casino player, this is really less of an issue, as Casumo is built for casino players first, which you'll learn about below.  If sports betting will be important for you, Casumo might not be your top option.

Casumo Ontario allows for free casino play without registration

Note one thing about Casumo Ontario if you intend to visit and browse around their casino before you sign up.  They have over 1600 games, many of which you can preview and play for free.  However, in order to preview or browse all the games at Casumo without full registration, find the "Explore Our Casino Games" link in large text. Once you find this page, you will be able to search and browse most RNG-style games for free, without signing up.  Not all legal Ontario online casinos offer this ability for free play previews.  Just note that the access and preview of games is a bit different than you might expect at Casumo. Prior to your registration, the preview area is a text-based search of games, rather than a typical interface where you might browse game tiles or categories. Once you sign up, you will have a full, graphical interface of their online and live casino to browse games, in addition to a search bar.

Does Casumo serve the rest of Canada?

The iGaming Ontario version of Casumo only serves players that are 19+ and physically present in Ontario.  However, Casumo does serve the rest of Canada from their international website that operates within the Malta Gaming Authority's jurisdiction.  The MGA is home to top casino brands (like Betway and Betsafe) that serve the provinces of Canada outside Ontario.  As a plus-point for players in the rest of Canada, this Malta-based version of Casumo also offers a solid sportsbook platform, which is good if you simply wish to complement your primary casino play.  It has most of the features for which you could ask. However, if sports betting is your primary interest, we do not have Casumo among our top betting sites for Canada, outside Ontario, given your options in this space.  

About Casumo as casino company, operator & brand

Casumo's parent company is based in Malta, which makes sense given this is the location of their main site's international gaming jurisdiction. Since 2013, Casumo has won over a dozen EGR awards, for things like innovation in gaming, their mobile casino and more.  This also makes sense, as Casumo is what we would consider to be a very "mobile-forward" online casino gaming brand.  We get into this more below.

Know that Casumo is not just some random brand that decided to serve Ontario. Casumo's Malta-based site serves a select few markets around the world that have yet to properly regulate their home online gambling markets.  These include Japan, India, Norway and Canada (outside Ontario).  They also have local licenses to operate in the UK, Ireland, Sweden and Spain, in addition to Ontario.  If you are a UK soccer watcher, you may recognise Casumo as a recent shirt sponsor of Reading FC in the EFL Championship. 

Casumo Ontario: a mobile-forward casino

Casumo has a fully responsive design.  This means that no matter your device resolution, whether computer, tablet or mobile, you get an experience that feels like it was designed for it.  A lot of online casinos really only feel best from a larger display, with you sitting in front of your computer.  But with Casumo, no matter where you travel or how you like to play, you get the same consistent and intuitive interface that feels and works the same as you navigate the menu, browse games, play games or use the search utility.  A unique, well-designed and well-thought-out platform.

Casumo Ontario gaming types: live dealer & online RNG casino games

As a gaming brand that was born as an online casino first, you would be correct in thinking that they might offer one of the more compelling legal Ontario online casinos.  Casumo of course provides a light and fun way to play RNG (Random Number Generator) online casino games or live-dealer casino games where a real-life person runs your game on camera from a studio.  When it comes to RNG games, they have nearly 1,600 to play.  Something for everyone.

In terms of live casino games, Casumo Ontario also has them in abundance from suppliers like Evolution Gaming and Pragmatic Play.  This means that you get full access to several variations of blackjack, roulette, baccarat and poker games like 3 card brag.  They also have live game shows like Monopoly, Spin a Win, Money Drop and more.  Live dealers and hosts take you through everything and interact with all players live in the chat. 

Casumo Ontario payment methods

Casumo Ontario accepts Visa & Mastercard credit and debit cards, Interac e-transfers and MuchBetter.

How fast are Casumo withdrawals in Ontario?

Once we had played our deposit amount once over and requested a withdrawal, our money landed in the bank in under two hours, via Interac. This is essentially as fast or faster than any other casino or sportsbook brand in Ontario - very good.

Casumo Ontario sportsbook review

Casumo is on the Kambi sportsbook platform, which is essentially the best sports betting tech stack that a gaming brand can go out and "rent" for use with their brand. Casumo has a really nice rendition of this platform. It's very simple to use and everything is really easy to find.  Use of your screen real estate is also good, so there is little wasted space, which makes for finding things more quickly. On the Kambi platform, you get access to a nice array of leagues and betting markets. You also get fully featured early cashout and Bet Builder, for same game parlays across leagues.

On the downside, Casumo tends to offer odds value that is below our top-rated brands for Ontario for important leagues and markets. For example, you will note that odds that look like 1.87/1.87 or -115/-115 on NBA or NFL point spreads or totals. Most Ontario bettors will touch these markets with their play and expect better value, given the average odds pairs tend to be around 1.90/1.90 or -110/-110.

Furthermore, if you intend to bet on markets outside the main result betting markets, Casumo does tend to accept fairly small stakes only.  So if you like to find value on less popular markets, you won't likely be able to bet as much as you might like as Casumo looks to limit their liability.  In the end, for Ontarian, the Casumo sportsbook is really about complementing their online casino, so you can get the odd bet down as you like. We wouldn't say that it's for hardcore sport bettors.

Casumo Ontario bottom line

Casumo is now a fully legal online sportsbook and casino option for players located in Ontario that could be an interesting option. However, all players should note the policy issues we highlighted having to play your deposit once over. If you can see past this, as you know you'll be playing your deposit fully, you may enjoy Casumo for a consistent user experience across devices, that will essentially feel the same from either your mobile, or your computer. Casumo is an interesting option, especially for casino or slots-focused players. 

As a brand born as casino-first, they are a good option for fans of all types of slots games, with a huge array of choice in this respect.  In Ontario, they do now offer sports betting, so if you want to place a sports wager from the same account alongside your casino play, you may do so from their intuitive platform. However, if sports betting will remain a focus point for your gaming pleasure, our top-3 sportsbooks offer more balance between sports and casino gaming offerings. For Casumo, the casino is the real deal, whereas the sportsbook is the side dish. So if you really care about the casino only, it might be great for you.
