Ontario casino online, mapped in stars
The map draws the 30 rooms this guide tracks as stars, grouped into six regional constellations. Tap a region to light it up and see its rooms. For online play, a three-step check shows whether a site is part of Ontario's regulated market.
The sky is schematic: the west is compressed and close stars are nudged apart. Ten stars sit on their town centre. Links to venue sites are unpaid.
Toronto's resort opened at Woodbine Racetrack on June 20, 2023. Pickering, Ajax Downs, Mohawk and Great Blue Heron, on Mississaugas of Scugog Island First Nation land, follow.
Two stars sit in Niagara Falls, Fallsview Casino Resort and Casino Niagara. The third is Elements Casino Flamboro, beside the Flamboro Downs racetrack.
The largest constellation, ten rooms, runs from Caesars Windsor on the Detroit River to small-town racetrack rooms in Clinton and Hanover. London's room is freshly renovated.
Casino Rama Resort sits near Orillia on Chippewas of Rama First Nation land. Innisfil's room is at Georgian Downs, and Wasaga Beach has a slots room.
Hard Rock Hotel & Casino Ottawa opened July 3, 2025 on the former Rideau Carleton Raceway site. Shorelines rooms shine in Belleville, Peterborough, Gananoque and Kawartha Downs.
Four stars stand far apart across the North: Sault Ste. Marie, Sudbury at the former Sudbury Downs, Thunder Bay and North Bay.

Three questions · about a minute
Is this online casino site registered in Ontario?
Three questions come first, and the answer is guidance, not a verdict. iGaming Ontario's directory of registered operators is the place that decides, so keep it open in another tab.
iGaming Ontario: the regulated market ↗ · AGCO: registered operators ↗
Is the site OLG.ca, OLG's own online casino?
Is the site's name listed in iGaming Ontario's directory of registered operators and their gaming sites?
Does the web address in your browser match the gaming site in that listing exactly?
This is OLG's own online casino, run separately from the iGaming Ontario market. Play is 19+, and My PlayBreak self-exclusion sits under its own tab in your account.
A site missing from the directory is not part of Ontario's regulated market. A site no longer listed has most likely stopped operating in Ontario. The guide's advice is plain: do not deposit there.
Treat it as a different site, even if the name and colours look the same. Open the gaming site from the link in the listing, not from a search result or a message.
The site appears in iGaming Ontario's directory, which means it is part of the regulated market. Set your limits first, before any deposit. BetGuard self-exclusion covers every regulated online site at once.
Online in Ontario
Two online doors in Ontario
The Alcohol and Gaming Commission of Ontario, the AGCO, is the provincial gaming regulator. It administers the Gaming Control Act, 1992, registers operators and suppliers, and sets the Registrar's Standards for Internet Gaming.
1iGaming Ontario
iGaming Ontario conducts and manages internet gaming offered through private operators and holds the operating agreements with them. That market opened on April 4, 2022. Created in 2021 as a subsidiary of the AGCO, iGO became a stand-alone agency on May 12, 2025. The AGCO still oversees it.
2OLG.ca
OLG.ca is the second door: OLG's own online casino, separate from the iGO market. On land, OLG conducts and manages the casinos. Private service providers such as Great Canadian Entertainment, Gateway Casinos, Mohegan and Caesars run them day to day.

About the online casino link
The button below goes to an online casino run by a partner. It is not this site and not OLG.ca. The partner can change, and this site earns a commission from it.
This guide does not vouch for the partner's registration. Run the three-step check above on any site, the partner's included. No offers of any kind appear here, by choice and under Ontario's advertising rules.
Ontario only. Must be physically located in Ontario to play.
Online casino play is for people aged 19+. Play responsibly, and call ConnexOntario at 1-866-531-2600 for free, confidential help, 24/7.
OLG.ca is OLG's own site. Not paid. Check any site in three steps.
Asked under the same sky
Questions
Is this site a casino?
This site is not a casino. It takes no bets and has no accounts. It is an independent guide to Ontario's land-based casinos, with a check for online sites.
How old do you have to be?
You must be 19 to enter a casino or slot facility in Ontario. The same age applies to online casino gaming and online sports betting.
How can you tell an online casino is legal in Ontario?
Look it up in iGaming Ontario's directory of registered operators and their gaming sites. The AGCO links to the same directory. The three-step check on this page walks through it, question by question.
Is OLG.ca part of iGaming Ontario?
OLG.ca is not part of the iGaming Ontario market. OLG runs it as its own online casino, separately.
Where does the Online casino button go?
It goes to an online casino run by a partner, and it is marked Ad. This site earns a commission from it, and the partner can change. The guide does not say anything about the partner's registration, so check it yourself.
Why are there no opening hours?
Hours change, and a stale time is worse than none. Readers should check each venue's own page before setting out.
