Halloween events for grown-ups in Ontario 2026
The Haunted Walk | Visit Kingston
With ancient Celtic origins and both pagan and religious influences, Halloween has evolved into a secular holiday in North America. It’s celebrated throughout September and October with decorations and activities, culminating in the final official date of October 31.
For young children, Halloween is a fun occasion for dress-up and trick-or-treating. But the holiday also offers frightful, hair-raising entertainment for adults.
During Halloween, the boundary between the living and the dead is blurred. From immersive haunted houses, scare parks and horror film festivals to sinister walking tours and costume parties, embrace the fright-filled fun of Halloween across Ontario.
These events are not recommended for young children or the faint of heart. Check for minimum age requirements before purchasing tickets.
