Two casinos, no rooms
Casino Ajax, at 50 Alexander's Crossing in Ajax, is open 24/7. Its floor holds 500 slot machines and electronic table games. There are no live table games and no poker room, and parking is free in an outdoor lot.
Elements Casino Mohawk stands at 9430 Guelph Line, Milton, at the Woodbine Mohawk Park harness track. Great Canadian Entertainment describes it as always open, 7 days a week. Table games run daily 12 PM to 6 AM. The poker room keeps Thursday to Sunday hours, 12 PM to 4 AM, and parking is complimentary. Neither venue has rooms of its own, and the operator's Casino Shuttle goes only to Toronto and Pickering.
The nearest bed
From Casino Ajax, the nearest casino hotel is Pickering Casino Resort, 5.1 km away. For Elements Casino Mohawk, it is Great Canadian Casino Resort Toronto, at 40.0 km. Both figures are straight lines between map coordinates from OpenStreetMap, not driving routes or drive times.
Overnight transport is uneven. The nearest scheduled stops to Casino Ajax are the DRT stops on Kingston Road at Alexanders Crossing. They are served by PULSE 900 and by the overnight route N1. Mohawk has no current scheduled public transit at 9430 Guelph Line, since all Milton Transit routes start and end at Milton GO.
