If you're looking for the best payout online casinos in Ontario, you came to the right place. The key factor to understand is Return to Player (RTP) — the percentage of total wagered money that a game is expected to pay back to you over time. A higher RTP means a lower house edge, which makes it one of the most reliable ways to measure a casino's long-term "payout" potential to you.
A quick but important caveat up front: in Ontario, fairness/RTP is regulated across all licensed operators; there is no single, permanent "casino-wide RTP." What actually drives your expected return is (1) the mix of high-RTP titles each site offers, (2) the specific game versions/paytables they choose, and (3) your choices within that library.
Ontario's regulated online casino market confirms integrity standards, but the best "payout" site for you is the one with the deepest bench of high-RTP games and transparent info per game.
Lets Dive Into Some Popular Options
In this guide, we compare four of Ontario's top licensed operators — Golden Nugget, DraftKings, Horseshoe and Bally Bet — to see which ones offer the strongest RTP line-up across slots, table games, and video poker.
Every brand here is fully regulated by iGaming Ontario, so fairness is guaranteed; what really separates them is the quality and quantity of high-RTP games available to players.
Best For High-RTP classics - Golden Nugget Casino
Golden Nugget launched in Ontario in 2025, plugged into DraftKings tech and known for curating very large libraries. Early coverage around the launch highlighted 2,000+ games and access to popular NetEnt/IGT/BTG titles—the very providers that publish many of the market's best RTPs (e.g., Blood Suckers 98%; several 96–97%+ BTG/Relax games). Functionally, that means plenty of high-RTP choices if you filter and favor the right titles.
- Verdict: If you like DraftKings' breadth but prefer Golden Nugget's UI/brand, you can still build a high-RTP portfolio here. It narrowly ranks behind DK mainly because DK's Ontario slot curation and exclusives are a touch stronger for RTP chasers.
Best overall RTP hunting ground - DraftKings Casino
DraftKings consistently fields one of the broadest high-RTP slot rosters in regulated markets, and Ontario is no exception. Independent roundups of DraftKings' highest-RTP/most efficient titles repeatedly feature evergreen picks such as Dead or Alive II (~96.8%), Blood Suckers (98%), White Rabbit Megaways, Thunderstruck II, and other >96% games—exactly the kind of catalog you want if you're optimizing for RTP. That breadth matters more than any single headline number.
On top of slots, DK typically carries multiple blackjack variants (often 99%+ with optimal play) and video poker options; if Ontario's lobby mirrors other DK markets, you'll find solid paytables somewhere in the mix. Use each game's info panel to confirm RTP; that transparency is standard in regulated Ontario sites.
- Verdict: Deepest high-RTP slot bench + good table/video-poker coverage = the strongest RTP toolkit for most players.
Best For Variety Of High RTP Slots - Horseshoe Online Casino
Horseshoe (live in Ontario since November 2024) brings a large, mainstream selection (800+ slots) plus live tables. That's plenty to find 96–97%+ slots and 99%-class table games, but Horseshoe's Ontario lobby tends to emphasize branded/popular titles over niche, super-high-RTP outliers. You'll still find efficient choices if you seek them out (e.g., NetEnt/Playtech 96%+ staples, blackjack with favorable rules), just not quite the same density of "RTP darlings" as DK/Golden Nugget.
- Verdict: A good "payout" option with brand trust and quick withdrawals; not quite the richest hunting ground for the very highest-RTP oddballs.
Best For High Payout Blackjack & Video Poker - Bally Casino
Bally Bet is licensed and operating in Ontario and continues to flesh out its casino catalog. For RTP-minded players, it's capable—especially for table games—but today its Ontario slot lobby is generally smaller than DK or Golden Nugget, so your pool of 97–98% "gems" is thinner. As Bally scales up content deals, this could change, but right now it's more of a competent all-rounder than a top RTP specialist.
- Verdict: Worth a look for blackjack/video-poker grinders; for high-RTP slot diversity, the bigger lobbies still win.
Tips For Getting The Highest RTP
Below are some tips to keep in mind when playing on any online casino -
- Slots: Prioritize titles with published RTP ≥96–97%. Examples include Blood Suckers (98%) and several NetEnt/BTG classics commonly available at DK/Golden Nugget/Horseshoe. Always check the in-game info panel because some slots ship multiple RTP profiles.
- Blackjack: Look for rulesets with 3:2 payouts, dealer stands on soft 17, double after split, and limited decks; these routinely produce 99%+ RTP with basic strategy. (Exact return depends on the rule set the site uses.)
- Video Poker: Seek full-pay variants (e.g., 9/6 Jacks or Better ≈99.54% with perfect play). If the paytable is short (e.g., 8/5), RTP falls fast—use a trusted calculator to verify.
Why You Can Trust These Ontario Casinos
All four brands cited above are in Ontario's regulated iGaming ecosystem; the province enforces standards around fairness/RNG and operator conduct. That's why operator-wide RTP claims are rare—Ontario focuses on per-game RTP disclosures, and your outcomes hinge on the specific titles/paytables you choose. Always verify the RTP shown inside each game and favor the top-returning versions.
Bottom line
If your #1 goal is maximizing expected return, start at DraftKings Ontario or Golden Nugget Ontario, filter for ≥96–97% slots (sprinkle in known winners like Blood Suckers 98%) and anchor your table-game play around favorable blackjack and full-pay video poker. Horseshoe is a strong alternative with mainstream depth; Bally Bet and PointsBet are fine but currently trail on high-RTP variety.
Responsible play reminder: even a 98% RTP still means a 2% house edge over time. Set limits and use Ontario's built-in RG tools.
