A Boutique Venue & Production Hub
Where Mississauga's speakeasy culture meets modern event versatility.
Our Story
One room, two identities
Below street level on Hurontario, the Underground Event Lounge is a boutique private venue designed for premium social, corporate, and entertainment events. The speakeasy spirit runs through everything — moody red light, a real stage, and rooms that convert from cabaret theatre to open celebration floor.
The space operates in two ways: as an exclusive private rental for your own event, and as a producer of original ticketed entertainment under Underground Productions.
