Montréal festival calendar 2027: the dates to plan around

Montréal’s festival year starts in the cold and barely stops until fall. These are the 2027 dates published as of November 2026. Festivals change their plans, so we say where each date comes from. Confirm on the festival’s own site before you book anything you can’t cancel.

Winter

Igloofest: January 14 to February 6. The outdoor electronic music festival takes over the Jacques-Cartier Pier in the Old Port. These dates come from a festival listing, not the organizer. Dress far warmer than you think you need to.

Montréal en Lumière: February 18 to 28. The official site has these dates for the winter festival of food, music and light.

Nuit blanche: expected February 27. The all-night event is part of Montréal en Lumière and falls on its final Saturday. We found this date in only one listing, so treat it as likely rather than confirmed.

Summer

Francos de Montréal: June 11 to 19. The official site has these dates for the 38th edition of the French-language music festival.

Montréal International Jazz Festival: June 25 to July 4. These dates come from festival listings. We haven’t seen them confirmed by the festival itself.

Just for Laughs: July. The comedy festival returned in 2025 after its 2024 cancellation. Exact days for 2027 aren’t available yet.

Osheaga: July 30 to August 1. These dates also come from festival listings rather than the organizer, so confirm them before you book.

How to plan around them

• Book hotels early for summer weekends. The Jazz Festival and Osheaga dates are the ones to watch if you’re coming from out of town.
• Check for free shows. Some festivals pair ticketed concerts with free outdoor programming, but this varies by festival and year.
• Take the métro. Downtown festival sites get crowded, and the STM trip planner will get you close to most of them.

Between festivals, the city still has plenty on. Our weekend guides list what’s on for each upcoming weekend, and they update daily.
