01Three floors, three uses
Three floors of the Main Building are named for visitors. The 1st floor is the casino, open 24 hours a day. The 2nd floor holds the Raceway Lounge, which belongs to the Western Fair District rather than to the casino. It shows simulcast horse racing from Canada and the US seven days a week, year-round. The 3rd floor is the Top of the Fair Restaurant.
Lounge hours run Monday to Wednesday from 5 pm to 11 pm, and Thursday to Sunday from 11:30 am to 11 pm. It may close earlier, depending on that day's simulcast schedule. The casino does not publish its own holiday hours, so a call to 519-672-5394 is the check for the 1st floor. The same address, 900 King St., is also home to The Raceway at Western Fair District, a Standardbred harness racing track run by The WFA Raceway Corporation.
02From 70,000 to 84,000 square feet
Work began on September 7, 2023, and the casino stayed open while it went on. The renovation and expansion were done in phases over 27 months, at a cost of over $50 million. Floor area was the plainest result. The building grew from 70,000 to 84,000 square feet.
A new name came at the end. On June 23, 2026, the casino was renamed Cascades Casino London. Before that date it was Gateway Casinos London, and the operator is still Gateway Casinos & Entertainment Limited. Readers searching under the old name will find the same casino, which now has a PROLINE+ sportsbook lounge and two places to eat.
03What the host community received
Since 1999, London has received more than $107 million from OLG as a host community for the gaming site at the Western Fair District. Gateway's role came later. Before May 2017, OLG itself ran the slots on the fairgrounds. That month Gateway took over the Western Fair slots from OLG as part of the Southwest Gaming Bundle. The arrangement runs under a 20-year Casino Operating and Services Agreement.
04Roads, parking and buses
The main entrance to the Western Fair District is on Rectory Street. Drivers coming along Highway 401 from the east take the Highbury Avenue exit. From Windsor or Sarnia, the exit is Wellington Street. Parking anywhere on the Western Fair District grounds is free. Once on the grounds, the casino is on the 1st floor of the Main Building (Grandstand).
London Transit runs three routes to the fairgrounds: 2 Dundas, 7 Wavell and 20 Cherry Hill. Riders from London International Airport take route 36 Industrial, which connects to route 2 Dundas. Stop locations and timetables are not given on this page and should be checked with London Transit before a trip.
