What the Property Actually Offers
Gateway Casino London operates at 900 King Street in London, Ontario, within the Western Fair grounds. The venue has been through several upgrades, and the most substantial change arrived in June 2026, when it reopened as Cascades Casino London after a full makeover. The refreshed floor now carries 891 slot machines, 18 live table games, and 28 electronic table game terminals. On top of that, there is a PROLINE+ sportsbook lounge on site and a racebook connected directly to Western Fair Raceway.
Slot play runs from low-denomination penny machines through to higher-limit units for larger wagers. At the tables, you will find Blackjack, Mississippi Stud Poker, and Mini Baccarat in regular rotation. A dedicated poker room is not confirmed here, which matters if your entire visit is planned around live poker.

The PROLINE+ lounge arrived with the 2026 renovation. PROLINE+ is the Ontario Lottery and Gaming Corporation’s in-house sports betting product, so its presence signals how OLG wagering is being plugged directly into Gateway-operated Ontario sites. Public information does not explain in detail how revenue or operations are split between Gateway and OLG in that lounge. That type of opaque arrangement is not rare for provincially linked sportsbooks, but it is worth being aware of.
The racebook deserves its own mention. It is tied into Western Fair harness racing, which means you can place pari-mutuel-style bets on live races while still having access to regular casino gaming under the same roof. That combined setup is not standard at every Ontario casino.
Regulatory Structure and Licensing
Gateway took over the London casino in December 2016 through the Southwest Gaming Bundle, a group of 11 Ontario properties acquired from OLG. Under that bundle, Gateway signed a 20-year Casino Operating and Services Agreement. OLG keeps the legal gaming mandate for the province, while Gateway acts as the commercial operator on the floor. Oversight at the top level sits with the Alcohol and Gaming Commission of Ontario (AGCO).
The end result is a layered model that looks like this: Gateway manages day-to-day casino activity, OLG retains the mandate and framework, and AGCO regulates OLG and the licensed operation. It is a two-tier structure used across Ontario’s provincially connected casinos, and the London property works fully inside that system.
| Regulatory Layer | Entity | Role |
|---|---|---|
| Commercial Operator | Gateway Casinos and Entertainment Limited | Day-to-day casino operations |
| Provincial Gaming Authority | OLG | Gaming mandate holder, COSA counterparty |
| Provincial Regulator | AGCO | Regulatory oversight of OLG and licensed gaming |
Any gambling at a licensed property involves a real possibility of losing money that you did not plan to lose. Ontario rules require responsible gambling tools and policies at provincially linked venues, but the exact list of programs active at this specific casino is not laid out in detail in publicly available documentation. Anyone who needs self-exclusion, information on limits, or help with problem gambling can approach AGCO or OLG directly. Both maintain province-wide support channels.
One practical point tends to matter more than any formal program. Setting a firm spending limit before walking through the doors generally works better than trying to improvise a stopping point once you are already on the floor. The physical environment, like most casinos, is simply not designed to make pausing easier.
Gateway’s corporate head office is in Burnaby, British Columbia. The group runs 31 casinos across British Columbia, Alberta, and Ontario. Majority control sits with Catalyst Capital Group Inc. through GTWY Holdings Limited. All gaming, dining, and entertainment transactions at Gateway Casino London are processed in Canadian dollars.
Planning a Visit - What to Confirm First
Casino hours are reported inconsistently by third-party websites, and those listings are not always updated. One source, PlayCanada, states that the casino is open 24 hours a day, with table games running roughly from midday until about 4:00 a.m. Another site, CasinosInCanada, mentions hours of 9:00 a.m. to 4:00 a.m. Tripadvisor shows patterns that look close to continuous operation but also do not fully line up. With that kind of variation, treating external listings as approximate only is safer.
The only reliable way to confirm is to contact the property itself before leaving home. You can reach the casino at 519-672-5394 or by email at [email protected]. Free on-site parking is available directly at the King Street location, which simplifies arrival.
A few points are worth settling before you show up:
- Confirm the current operating hours by phone or email, and if table games are important for your visit, verify their schedule specifically.
- Check the gaming floor information at gatewaycasinos.com so you have a sense of slot denominations and which table games are active.
- If you plan to spend time in the PROLINE+ lounge, review OLG’s current terms, markets, and eligible bet types online in advance so there are fewer surprises on-site.
- Bring valid government-issued photo ID. Staff regularly verify age at Ontario licensed casinos, and being turned away at the door is very possible without proper ID.
- If you are interested in racebook wagering, look up the Western Fair Raceway harness racing calendar ahead of time, as live racing dates influence what is available to bet.
One more practical detail: the sportsbook lounge, even though physically inside the casino, operates under OLG’s PROLINE+ framework. For detailed questions about markets, settlement rules, or wagering limits, OLG support channels are typically better sources than the casino floor staff.
