Toronto’s free all-night celebration of contemporary art returns Oct. 3 at 7 p.m. to Oct. 4 at 7 a.m., transforming the city’s public spaces and familiar place into extraordinary landscapes. Celebrating its 20th anniversary, this year’s theme is “Tomorrow’s Memories” reflecting on two decades of Nuit Blanche while looking toward the future.

The program features projects from local, national and international artists, including curated exhibitions presented by the City of Toronto. Expect monumental installations, live performances, participatory works and unexpected encounters—all free.
