Proline Sportsbook Review 2026 - Is OLG Proline+ any good?
Many Ontario sports bettors know the Proline brand very well from the parlay-based wagering game that launched in the early 1990s, which required players to fill out tickets in-person at local lottery retailers. Now that single-event sports betting has become legal in Canada, we can happily report that not only can you bet on single events online with "Proline+", the odds value that is now available from this OLG online sportsbook are as competitive as just about any brand within the iGaming Ontario ecosystem of legal betting operators. We get into our Proline+ review, addressing their highly improved odds & all the key points that make Proline+ a solid option for Ontario players. We start with the number one reason you should play at Proline+: It's all about where you live.
Not just another sportsbook, with Proline+, unlike all other legal brands, all proceeds stay in Ontario
In a moment, we're going to explore all the great things about the Proline+ playing experience, including odds value, betting features & more. However, the reality is that there are now dozens of betting brands in the legal iGaming Ontario ecosystem of operators. While the Proline+ experience sits right alongside the best legal Ontario sportsbooks, understand that all iGaming Ontario operator brands keep 80% of all gaming revenue, and the province itself through iGaming Ontario keeps just 20%. This revenue split is totally fair, and similar to other competitive jurisdictions in Europe that want to offer consumer choice in a regulated market, alongside their government-owned gaming brands.
Since the Ontario Lottery & Gaming Corporation (OLG) runs Proline+, you know that 100% of revenue that may be kept through your play stays in Ontario for reinvestment. So if you want to have a great gaming experience, with peace of mind in knowing that all your money stays at home, there is literally no better option for online sports betting in Ontario than Proline+.
But wait, you have concerns over whether or not Proline+ actually has a good sports betting experience, right? Yeah, we understand. The reputation they created through the old-school Proline game at lottery retailers may be something you need to overcome, but we can tell you that Proline+ isn't your dad's Proline game. Let's put your mind at ease, starting with their new platform and odds value proposition.
How is the new Proline+ Ontario online sportsbook platform?
Proline+ comes to Ontarians on the "Kambi" sportsbook platform. Within iGaming Ontario alone, there are no less than six operator brands that use it. Kambi is a B2B sportsbook technology provider, and likely the premier one at that. With it, you get solid odds value across leagues and sports, including live, in-play markets, as well as a host of futures or long-term markets. They also have a robust early cashout feature so you can take partial wins on your bets before the event has concluded. We look at these aspects in more detail below, but rest assured, Proline+ is now on a proper sports betting platform.

How are the odds at OLG's Proline+ sportsbook? Have they improved?
Prior to the legalization of single-event wagering, the next most pressing problem with the traditional Proline game was their odds value proposition, which was seen as being uncompetitive. Back in the day, the odds for the traditional Proline game were very low, but things have changed in a big way. With the Proline Plus online sportsbook, you can completely forget about the notion of uncompetitive odds when it comes to the main betting markets for the so-called "big four" sports leagues.
Proline+ has very competitive odds for NFL, NBA, NHL & MLB and top soccer leagues
For these most popular leagues, Proline+ has made a clear decision to skew toward offering significantly better-than-average odds value in terms of the "odds margin" or "sportsbook hold" they integrate into their odds. Let's start with the betting markets that matter the most for these top leagues in the province: the "money line" (game or match winner), "point spread" or main handicap market like "run line" or "puck line", and the main "totals" or "over/under" market. Proline+ uses a "hold" or "margin" on these betting markets of just over 4%.
Compare this to most other legal Ontario sportsbooks that use a "margin" or "hold" on these markets just above 5%. When it comes to odds value, don't think of this as a mere 1% difference between Proline Plus and the other sportsbooks, because it is actually a 20% price difference on average. In other words, of all the money bet on a given betting market, Proline+ uses odds that keep 20% less money for their own revenue, compared to the vast majority of legal Ontario sportsbooks.
This is a huge difference in odds value when you as a bettor are aiming to stay in profit over a long period. With Proline+, your odds will tend to be higher than average, more often, which means higher payouts when you win. So if these main four leagues of the NFL, NBA, NHL and MLB will make up the vast majority of your betting, very honestly, whether you are a recreational bettor or one that really shops for the best odds, Proline+ is really a must-have sportsbook in Ontario. For top soccer leagues, Proline+ is also very competitive and always offers a large array of markets, all with far better odds than before.
What about the Proline Plus odds value on futures markets?
When it comes to popular outright winner or "futures" markets, for the same four popular leagues, again the odds remain very competitive at Proline Plus. The beautiful thing about being on the Kambi platform is that the odds do not become skewed by bets that might be popular in Ontario. Since they serve customers around the world, not just via Proline+ on OLG, the odds reflect a much wider swath of bettors, keeping odds higher on locally "public" teams like the Leafs or the Senators or the Jays or the Raptors. This is a big plus on odds value for Ontario bettors that may want to bet on their local team.
Does the Proline+ online sportsbook offer live in-play betting?
Yes. Proline+ makes it super easy to find events that you may bet upon in the moment. As you access their platform, in the main left navigation, right near the top, you can find the "Live Right Now" icon. Click or tap this to open a page that has all the ongoing events of the moment, across all sports. If you want to see the live events for a particular league or sport, you simply navigate to that league as normal and Proline+ provides you with two obvious tabs "Live" and "Upcoming". Simply toggle between these tabs to find your in-play betting options, as well as those for upcoming pre-match betting.
Does Proline+ sportsbook have an early cash out feature?
Yes, Proline+ supports "cash out" for many betting markets on important sports and leagues so that you may secure a partial win or protect stake money before your event has reached its natural end. To find your potential cash out offers, simply navigate to your "My Bets" area. If cash out is available, you will see that the "cash out" button is active, along with the current available amount. Simply tap or click that button to request the cash out. As with all these kinds of features, it is dynamic and having a cash out value available is not always guaranteed.
Does Proline+ sportsbook have same game parlays?
Yes, they do, now on the Kambi sportsbook platform, you get a very robust ability to play Same Game Parlays. "SGP" will be displayed to you for every game or event that they are available, but this now essentially includes all major events across sports. Simply click or tap on any game with the noted "SGP" to drill-in to see all the available markets.
Does Proline+ sportsbook accept Interac? Proline+ payment methods
Yes, Interac is available at Proline+ for both deposits and withdrawals. To keep things simple, ideally, your OLG-dot-ca account uses the same email address as used for your Interac e-transfers. It just makes things easier in terms of the financial compliance checks that must be done to ensure sure the source of the money into your betting account, matches the destination for the money that gets withdrawn to the bank account. Proline+ / OLG Casino also accept Visa and Mastercard debit and credit cards. Note that debit cards are far cheaper to use, as credit cards used at any gaming site in Ontario come with "cash advance" interest rates and flat fees from the moment of your deposit. Use debit or Interac if you have those options available.
Can you play slots, online casino & live dealer games at Proline+?
Essentially, yes. Proline+ is actually the online sportsbook gaming vertical under the olg-dot-ca website. When you move to register with the Proline+ online sportsbook, you actually do so by creating your OLG online gaming account.
With this one account, you get access to Proline+, but also to the OLG Casino, which gives you access to their online slots & casino games, plus their wide array of live dealer games where a real person runs your Blackjack, Roulette or Baccarat game on-camera from their gaming studio. If you're curious about the OLG Casino experience, we've got a full OLG online casino review for you. Note that when you play at OLG Casino, while it will be under the same username and profile, and they now use a one-wallet system so you only need to fund one account balance to play across the site.
Is Proline Pools also available to play online?
Not any more. From January 2026, OLG has shut the online version of Proline Pools and they are exploring new ways to improve it and bring it back in the future.
Proline+ bottom line: a solid online sportsbook option for Ontario bettors
Proline+ has done a great job to provide Ontario players with a far better platform and value offering than players would be used to with to the traditional paper Proline game. Not only does Proline+ now provide solidly good odds value, they actually provide great odds value on the sports that Ontarians wager on the most. By using a significantly lower "odds margin" or "sportsbook hold" compared to some of the top legal iGaming Ontario operators, Proline+ often has some of the highest available odds for soccer, NFL, NBA, NHL & MLB betting, which makes for higher payouts if you win.
With an excellent overall betting platform across devices, you no longer have to sacrifice the quality of your sports betting experience when you consciously choose the option that reinvests all proceeds back into Ontario. Now, you get the best of both worlds. Even if you just want a solid sportsbook experience with great odds value and you are unconcerned with where your gaming proceeds might land, Proline+ on its own merits should be among the top few brands you consider.
When we weigh the fact that Proline+ is the only legal online sportsbook that returns all proceeds from play for reinvestment in the Province, you can understand why we at SNBET have ranked them one of our recommended sportsbook options for sports bettors in Ontario.
