Halloween 2026 Celebrations In Mississauga

Mississauga has plenty of atmosphere once October arrives, with decorated neighbourhoods, seasonal community activities and Halloween events appearing across the city. Port Credit, Streetsville and the areas around Celebration Square give residents different places to spend an autumn evening, while parks and community spaces make daytime Halloween plans easy for families. Halloween 2026 falls on a Saturday, giving people a full weekend for costumes, movies, seasonal activities and local gatherings. Mississauga’s location also puts larger Toronto performances and Halloween events within reach for adults looking beyond the city for additional plans.

Fun Things To Do In Mississauga On Halloween 2026

Halloween in Mississauga can include everything from pumpkin activities and family celebrations to costume events and seasonal entertainment. Adults looking farther across the GTA will also find theatre productions, themed cruises and large costume nights in Toronto throughout October. The events below come from the provided listings and all take place in Toronto rather than Mississauga, so travel should be factored into any plans.

1) A Nightmare on Strip Street - Toronto | The Royal Theatre

Classic horror gets turned into an adults-only stage parody at A Nightmare on Strip Street - Toronto. Running from October 9 to November 1, 2026 at The Royal Theatre on College Street, the production mixes horror satire, comedy and choreographed live performance. Familiar slasher-film characters and genre clichés form the basis of the show, with multiple performances scheduled from Wednesday through Sunday. Each performance runs for roughly 90 minutes. The production is restricted to guests aged 18 and older, making it an adult theatrical option rather than a general Halloween attraction.

2) Haunted Halloween Boat Party Cruise 2026 - Toronto | The Empress of Canada

Toronto Harbour becomes the setting for Haunted Halloween Boat Party Cruise 2026 - Toronto on October 30, 2026 aboard the Empress of Canada. The 19+ event runs from approximately 8 PM to 12:30 AM and uses three levels of the vessel for music and entertainment.

The Halloween-themed cruise uses three decks, with two DJs and two separate music areas running during the evening. Costumes form part of the theme, while the route provides nighttime views of Toronto’s waterfront and skyline. The organizer lists the event as age-restricted, so it is intended specifically as an adult Halloween nightlife event rather than a family cruise.

4) House of Horrors Halloween Costume Party | Oria Nightclub
