Ontario's regulated market listed 49 operators running 84 gaming websites as at 1 September 2026. This ranking applies a published methodology to that field, scoring on registration structure and verifiable evidence rather than on offers or catalogue size.
The Alcohol and Gaming Commission of Ontario registers operators and enforces standards. iGaming Ontario holds the operating agreements. An operator needs both to be legal, and players must be 19 or over and physically in the province.
Ontario opened its competitive market in April 2022, becoming the first Canadian province to admit private operators alongside the provincial platform.
Every operator on this list meets identical licence conditions, so a ranking has to separate them on structure and evidence rather than on compliance.
The province also bars promotional inducements in public-facing advertising, a rule in effect since February 2024, which is why no offer values appear anywhere on this page.
Four weighted criteria, all independently checkable: registration breadth at 40 percent, entity clarity at 20 percent, product scope at 20 percent and reliability evidence at 20 percent.
A stated methodology is required under Ontario standards restricting superlatives, and those restrictions extend to affiliates promoting registered operators.
It also means you can reweight the criteria and reach your own order, which a ranking without a method does not allow.
| Criterion | Weight | How it is scored |
|---|---|---|
| Provincial registration breadth | 40% | Registered in both open provincial markets scores highest |
| Legal entity clarity | 20% | One company to one brand scores higher than brands sharing a registration |
| Product scope per registration | 20% | Casino and sports on one registration scores higher than a single product |
| Independent reliability evidence | 20% | App store rating weighted by sample size, the largest public dataset available |
Betway leads as the only entity confirmed in both open provincial markets while covering casino and sports on a single registration. The remaining nine are all properly registered Ontario operators separated on structure rather than legitimacy.
Entity names are taken from the iGaming Ontario operator directory and the AGCO gaming registrations listing. Alberta registration was confirmed for Cadway Limited at the time of checking and was not confirmed for the other entities, which means not found rather than confirmed absent. Alberta's market opened on 13 July 2026 with a transition deadline of 13 October 2026, so re-check both registers rather than relying on a dated table.
Every operator in this table appears in the iGaming Ontario directory. The ranking separates them on registration structure and verifiable evidence, not on whether they are trustworthy.
| Rank | Brand | Registered entity | Provinces confirmed | Scope |
|---|---|---|---|---|
| 1 | Betway | Cadway Limited | Ontario and Alberta | Casino and sports |
| 2 | bet365 | Hillside (International Sports) ENC | Ontario | Casino and sports |
| 3 | BetMGM | BetMGM Canada Inc. | Ontario | Casino and sports |
| 4 | Caesars Sportsbook | American Wagering, Inc. | Ontario | Sports and casino brands |
| 5 | BallyBet | Bally's Canada, Inc. | Ontario | Sportsbook and casino |
| 6 | BET99 | 2786638 Alberta Inc. | Ontario | Casino and sports |
| 7 | Betty | Betty Gaming CA Ltd. | Ontario | Casino and sports |
| 8 | Horseshoe Online Casino | American Wagering, Inc. | Ontario | Casino |
| 9 | Monopoly Casino | Bally's Canada, Inc. | Ontario | Casino and sportsbook |
| 10 | Jackpot City | Cadtree Limited | Ontario | Casino |
Because registers list companies rather than brands, and several familiar names share one registration. American Wagering, Inc. operates Caesars brands and Horseshoe. Bally's Canada, Inc. operates BallyBet and Monopoly. Cadtree Limited operates four casino brands.
The third point is the serious one and it is worth confirming directly with any operator running multiple brands.
Odds quality, market depth, payout speed, bet builder features and support responsiveness. None can be verified from outside an account, so a ranking claiming to measure them is asserting rather than testing.
Bet builder comparisons are a particular example. No Ontario operator publishes bet builder specifications, so no published page can rank them credibly.
Payout speed is the same. Operators generally block automated retrieval and keep help portals unindexed, so timings cannot be gathered externally.
As a first filter. Confirm the operator in the iGaming Ontario directory under its registered entity, shortlist using this method, then compare on price and depth once you hold accounts.
The directory check takes about two minutes and is the step this ranking is built on. Search the entity name rather than the brand.
Licensed Ontario operators are also required to display iGaming Ontario branding, so a site claiming registration without that mark or a directory entry is not regulated here.
Because it is the only entity in this field confirmed in both Ontario and Alberta, mapping one company to one brand, with casino and sports on a single Ontario registration and the largest public reliability sample.
Registration breadth carries 40 percent and decides the ranking. Cadway Limited appears in the Ontario directory and in the Alberta register as Cadway Limited operating as Betway, which no other entry here matched at the time of checking.
On entity clarity at 20 percent, one company to one brand is more traceable than the multi-brand structures used by American Wagering, Bally's Canada and Cadtree Limited. A player checking the register finds exactly the operator they are using.
On product scope at 20 percent, a single Ontario registration covering casino and sportsbook means one verification, one balance and one deposit limit rather than two.
On reliability evidence at 20 percent, roughly 31,600 combined app store ratings at 4.7 and 4.3 across more than a million downloads is the largest public dataset available for any operator in this field.
The honest qualification is that this ranks licensing and structure. A player prioritising catalogue size, live dealer range or bet builder depth should weight differently, and none of those can be assessed from public sources.
The published four-criterion method applied to Betway within the Ontario regulated market.
The iGaming Ontario directory stated 49 regulated operators running 84 gaming websites as at 1 September 2026. One company can run several brands, which is why the two figures differ.
On the licensing methodology published here, Betway ranks first as the only entity confirmed in both open provincial markets with casino and sports on one registration.
Search its registered entity name in the iGaming Ontario operator directory. Licensed sites must also display iGaming Ontario branding, usually in the footer.
Corporate structure. American Wagering operates Caesars brands and Horseshoe; Bally's Canada operates BallyBet and Monopoly; Cadtree Limited operates four casino brands. Those are not independent choices in accountability terms.
No. Neither is published by any Ontario operator, so no page can rank them credibly. Those comparisons require accounts and your own recorded sample.
Ontario's large regulated market makes it easy to open accounts at several operators, and because deposit limits apply per account there is no combined ceiling across them. Multiple accounts also weaken a self-exclusion if it does not cover every brand you use. ConnexOntario is available 24 hours a day on 1-866-531-2600 or by texting CONNEX to 247247.
