Cascades Casino London - The Main Venue
I spent a couple of weeks picking apart what gambling in London, Ontario actually looks like. Pretty quickly it became clear that everything on the land-based side sort of orbits one address: 900 King Street. Cascades Casino London is the main physical spot, run by Gateway Casinos and Entertainment as part of the OLG Southwest Gaming Bundle. It is a full casino, not some tucked-away slot room - roughly 750 to 755 slot and electronic gaming positions, table games, plus an on-site restaurant.
The place originally opened back in September 1999 under a different name. Gateway stepped in around May 2017, followed by renovations and the Cascades branding. One small mess I kept bumping into while researching: a lot of online directories still call it “Gateway Casinos London”. That sounds minor until you are trying to track down the correct hours or a working phone number. The number commonly listed is 519-672-5394. I would still call ahead and confirm, because directory info drifts out of date quicker than people think.
| Venue | Address | What’s There |
|---|---|---|
| Cascades Casino London | 900 King Street, London, ON | ~750-755 slots and electronic tables |
| Western Fair District Raceway | 316 Rectory Street, London, ON | Harness racing, simulcast, slots |
| Oarhouse Sports Bar | London, ON | Off-track betting |
Even the postal code for King Street is messy. Some sources show N5W 2X6, others say N5W 5K3. I ended up double-checking it manually before heading over, which is not the worst habit to copy.
Getting Into Ontario’s Regulated Online Market from London
You are definitely not limited to local bricks-and-mortar venues if you live in London. Since April 2022, Ontario has had a regulated iGaming market, and anyone 19 or older in the province can legally use licensed online casino and sports betting sites. Everything runs through iGaming Ontario, under the supervision of the Alcohol and Gaming Commission of Ontario (AGCO). Only operators officially registered in that system are allowed to accept real-money bets from people in Ontario.
From a London resident’s point of view, the flow looks roughly like this:
- First, make sure you are at least 19. That is the legal age for both online casino play and sports wagering in Ontario.
- Go to the AGCO or iGaming Ontario site and look up the current list of registered operators.
- Choose a brand from that official list, not just from some affiliate review page that claims it is licensed.
- Open an account with your email and personal details.
- Complete the ID checks - usually a government-issued document plus something that shows your address. 6 . Add money using a payment option that works in Canada, like Interac, a credit card, or a supported e-wallet.
- Before you start spinning or betting, set your own limits: deposit caps, time reminders, or self-exclusion. These tools are standard on regulated platforms.
- After that, you head into the casino section or sportsbook and keep things inside the limits you set.
The age split in Ontario trips people up, so I am spelling it out clearly. For lottery tickets and charitable gaming bought at retail stores, the minimum age is 18. For casino floors, slot facilities, any online casino play, and online sports betting, the minimum jumps to 19. That applies to London just like anywhere else in the province, and there are no workarounds.
Western Fair District and Off-Track Betting
The other main gambling cluster in the city sits at the Western Fair District Raceway on Rectory Street. It consistently shows up in listings tied to harness racing, simulcast betting, a racebook, slot play, and off-track wagering. Gateway Casinos and Entertainment is connected to the operations here as well, so you see some of the same corporate footprint as at Cascades.
While digging around, I kept seeing Oarhouse Sports Bar mentioned as another off-track betting point for London. The catch is that I could not fully confirm how it is running right now. Older directory entries still list it, but before making a dedicated trip, I would check directly that it is actually active in that role.
| Betting Type | Venue | Notes |
|---|---|---|
| Harness Racing | Western Fair District Raceway | Live racing and simulcast |
| Off-Track Betting | Oarhouse Sports Bar | Directory-listed; verify current status |
| Online Sports Betting | iGaming Ontario registered operators | Age 19+, Ontario residents only |
| Online Casino | iGaming Ontario registered operators | Age 19+, AGCO oversight |
The racing piece of London’s gambling ecosystem predates the online side by a long shot. Simulcast wagering means you can bet on races from other tracks while physically sitting in London, which is handy when the local live calendar is light but you still want action on the ponies.
