Walk into the Glebe on the third Saturday of October
Bank Street is closed to traffic and lit for the evening, and the storefronts along Glebe Avenue and Bank Street have been given over to the Glebe Halloween Village. Costumed families drift between porches and shop windows; the neighbourhood's restaurants stay open late, and the whole strip becomes a slow-moving promenade rather than a street you pass through. It runs on a single October day — the 17th in the 2026 season — so plan your trip around it rather than hoping to stumble onto it.
Two neighbourhoods over, Hintonburg runs its own version the same day: Hintonburg Howl-O-Ween takes over Parkdale Park on October 17. Come in costume, expect a crowd of local kids and dogs, and treat it as the west-end counterpart to the Glebe's evening. If you're in the city for only one weekend in October, this is the one where both happen at once.
Let Saunders Farm scare you, then feed you
Saunders Farm is where Ottawa does Halloween at scale, and it runs two overlapping productions. FrightFest, the farm's scare event, opens September 26 and runs through October 31 — haunted trails, actors in the dark, and the kind of line-up that rewards arriving early. PumpkinFest occupies the same grounds from September 26 to November 1, an autumn festival built around the pumpkin harvest and daylight hours. You can pair them: an afternoon at PumpkinFest with children, then hand them off and return after dark for FrightFest. Both are seasonal fixtures rather than one-night events, so a weekday visit is quieter than a weekend.
Spend Halloween week between the market and the museum
The last days of October are the densest stretch of the season, and most of it happens indoors or under market awnings — useful if the weather turns.
- Day of the Dead Festival, October 30 to November 1, in the ByWard Market. Three days of altars, music and food in the stalls and streets around the market, timed to run through Halloween itself. This is the closest thing the city has to a public street celebration that week, and it's free to walk through.
- Nature Nocturne – Black and White Ball, October 30, at the Canadian Museum of Nature. The museum's after-hours party, dressed for the occasion, with the galleries open and a bar in the middle of it.
- The Phantom of the Opera: Silent Film with Live Soundtrack, October 25, at the Ottawa Art Gallery. The 1925 film with a live score in the room — the most atmospheric single ticket of the month, and it sells on the strength of the organ alone.
- Elmvale Ward Seance, October 9 to November 30, at 2935 Conroy Road. A seasonal production running right through the period rather than on one night, which makes it the easiest thing to slot in when everything else is sold out.
Fill the rest of October with music and small halls
Halloween isn't the only thing on. Capital Music Week runs October 2 to 10 across downtown Ottawa, with venues within walking distance of each other and a programme that rewards wandering between sets. Live from the Booth takes over Sparks Street from June 4 to October 10 — catch it in its final week if you're arriving early in the month. Janina Fialkowska Celebrates 75 plays the Carleton Dominion-Chalmers Centre on October 13. The Gatineau Hills Fiddle Festival runs October 22 to 25 at La Fab sur Mill Arts Centre, just across the river and worth the drive for the contrast alone. And the Ontario Festival of Small Halls spreads across venues province-wide from October 2 to December 5, which means there is almost certainly a hall within reach wherever you're staying.
If you want a single evening that isn't Halloween-themed at all, ShakesBEER 2026 lands at Beyond The Pale on October 18, and the Ottawa International Writers Festival runs October 22 to 25 at Library and Archives Canada.
Know when to come, and what to eat while you're here
Book for the middle two weekends of October if you want the neighbourhood events; book the final weekend if you want the ByWard Market at its busiest. The 17th carries the Glebe Halloween Village and Hintonburg Howl-O-Ween, and the 18th brings Geek Hoard Haul-oween to Sensplex Kanata, so choose your base accordingly, and expect west-end and east-end events to be an hour apart by car.
For food, follow the markets rather than a restaurant list. The ByWard Market is where you'll eat during the Day of the Dead Festival, with the stalls and surrounding kitchens doing the work. Parkdale Market hosts Vegans Who Snack on October 24, a good excuse to graze your way through a Saturday morning. And One World Bazaar, running September 17 to November 22 at 6110 Mitch Owens Rd, is the long-running seasonal market on the city's southern edge — the kind of place you go for gifts and end up staying for lunch.
Start with the calendar, then book the weekend
Ottawa's Halloween season is long — Saunders Farm opens in September and the ByWard Market festival closes it out on November 1 — which means you have real choice about when to arrive. Pick the weekend of October 17 if you want street-level neighbourhood energy, or the final days of the month if you want the market, the museum party and the silent film in one stretch. Check the Ottawa Festivals calendar for exact times and tickets, book Saunders Farm and Nature Nocturne early, and build the rest of your days around whichever neighbourhood you're sleeping in.
