Saunders Farm FrightFest
Dates to be announced
Five immersive haunts, haunted hayrides and live performance on a farm outside Ottawa.
Nightmares Fear Factory
Niagara's permanent haunted house, running year-round at the top of Clifton Hill.
One of the few haunts in Canada that operates all year rather than just in October, and famous for photographing visitors at the moment they break and run.
Short compared with a full scream park, but the reputation is earned — the counter of people who did not finish is a real thing.
Also in Ontario
