Ottawa is about to stay up all night for art. Nuit Blanche is returning to the city for the first time in roughly a decade, transforming the ByWard Market into a free, immersive nighttime art experience from Saturday, September 26 at 7 p.m. through Sunday, September 27 at 7 a.m.
Here's what to know before you head downtown.
1. It's been 10 years since the last one
Ottawa last hosted Nuit Blanche in 2015. The 2026 edition is produced by Les Forains, the same company behind Nuit Blanche in Toronto and Montreal, and comes with support from the City of Ottawa's Nightlife Office.
2. Admission is completely free
Everything on offer during the overnight event is free to attend, from the installations to the performances spread across the festival footprint.
3. The ByWard Market becomes the main stage
Organizers say the ByWard Market will be transformed into a vast, immersive nighttime art experience for the night. Beyond the Market itself, venues stretch to York Street, William Street, ByWard Market Square, Confederation Park, Arts Court, and the National Arts Centre.
4. Eventi Verticali: CUBO is a live performance piece
One of the festival's marquee installations is a suspended cube of light and shadow where dancers become part of the structure itself. CUBO performances run three times through the night, at 7:20 p.m., 9:20 p.m., and 11:20 p.m., so it's worth timing a visit around one of those slots.
5. PRISMATICA turns light into a maze
Another featured piece, PRISMATICA, is a glowing labyrinth built from 25 rotating prisms, meant to be walked through rather than simply viewed.
6. IMPULSE and MONUMENTS round out the big installations
IMPULSE is a giant seesaw that generates waves of light and sound as people use it, while MONUMENTS projects monumental human portraits onto trees around the festival grounds, turning the city's own greenery into a canvas.
7. This year's theme is "Where Innovation Meets Art"
The 2026 event is built around the theme "Where Innovation Meets Art," tying together the light-based installations, live performance, and public space design that define the festival's return.
Why organizers say it matters
Les Forains executive director José Bertrand said the appeal of Nuit Blanche is that it has no barriers to entry. "What's beautiful about Nuit Blanche is that it's open to everyone. It's art without walls, music without tickets, imagination without limits," he said.
Ottawa Mayor Mark Sutcliffe pointed to the event as part of a broader push to keep the city's event calendar full, saying the city plans to "keep that momentum going by adding more great events like Nuit Blanche in 2026." Ottawa Tourism's Catherine Callary framed the night as a showcase opportunity, calling it "a great spotlight for local artists and cultural institutions to showcase their work."
For Ottawa residents who missed the last one in 2015, or who weren't around for it, Saturday night is the first chance in a decade to see the ByWard Market reimagined as an all-night art walk, free of charge and open to anyone willing to stay up for it.
