Halloween possesses downtown Oshawa
Get ready, ghouls and goblins, downtown Oshawa is turning delightfully spooky for one night only during the Oshawa Halloween Boo Bash "Spirits Rise" 2025 free event! 🎃 Join us for a frightfully fun first ever Halloween bash packed with pumpkins, costumes, music, vendors, and eerie surprises around every corner, literally! Bring the whole family for a night of not-too-scary thrills and ghostly good times!
IMPORTANT!
It's challenging to balance between people with sensitivities to scares both young and old and those who are looking for a little more fright in their night. To appeal to both, we'll have NO SCARE ACTORS in Krampus, The Saw is Family and Demon Child as well as the wandering JASON between 1PM - 3PM. READ OUR WARNINGS
Shadows get stretched as downtown is transformed into a halloween playground. Do you dare?
SCARE ZONES
Meet the Toronto Ghostbusters team, 30 ft. Stay Puft, 20 ft. high tentacles, ECTO mobile and Slimer containment unit!
Weave carefully through the whispering pine trees because you never know who, or what, may be lurking just on the other side.
Grab your friends and take your picture in front of one of the most iconic backdrops ever to hit the silver scream.
Dodge a fierce roller skater gang in this post-apocalyptic scare zone—thrills, chills, and wheels of terror await!
SPOOKY PHOTO OPS!
GALLERY OF GHOULS
Get your cameras ready... our Gallery of Ghouls offers more Instagram moments than you can shake a broomstick at! Take your pic at these PhotoOPs.
WANNA WEAR A COSTUME?
It's a Halloween event, of course you can wear a costume! In fact, we encourage it. The more creative and over-the-top, the better! But we do have a few guidelines we need you to consider. You can find our costume guidelines here.
