Montreal’s festival calendar runs hardest from January through August, an outdoor winter light festival through the summer’s back-to-back music and comedy season. These six dates are the ones actually worth planning a trip around, plus the one weekend that pushes hotel prices citywide even though it isn’t technically a festival. Check hotel rates well ahead if your dates land near any of them.
6 festivals and events, at a glance
| Event | 2026 Dates | Note |
|---|---|---|
| Igloofest | Jan 15-Feb 7 | Outdoor winter electronic music festival |
| Montréal en Lumière & Nuit Blanche | Feb 27-Mar 7 (Nuit Blanche Feb 28) | Light, food, and an all-night city-wide event |
| Formula 1 Canadian Grand Prix | May 22-24 | Not a festival, but the single biggest hotel-price spike |
| Montreal International Jazz Festival | Jun 25-Jul 4 | One of the world’s largest jazz festivals |
| Just for Laughs | Jul 15-26 | The world’s largest comedy festival |
| Osheaga | Jul 31-Aug 2 | Music and arts festival on Jean-Drapeau Park’s island |
Winter: Igloofest and Montréal en Lumière
Igloofest, January 15 to February 7, 2026, is an outdoor electronic music festival that runs regardless of the cold, dress for it. Montréal en Lumière, February 27 to March 7, pairs light installations and a major food program with Nuit Blanche on February 28, a single night where museums, galleries, and venues across the city stay open until the early hours. Winter in Montreal is genuinely cold, -10 to -20°C, but the RÉSO underground city keeps both festivals reachable without much time spent outside.
Late spring: the Formula 1 weekend
The Formula 1 Canadian Grand Prix, May 22-24, 2026, isn’t a cultural festival, but it’s worth flagging on its own: hotel rates across the city spike hard around it, and it’s the single event most likely to wreck a budget trip if you don’t book around it deliberately. Formula E, for what it’s worth, hasn’t run in Montreal since 2017, so don’t plan around that instead.
Summer: Jazz Festival, Just for Laughs, and Osheaga
Summer is when the calendar stacks up. The Montreal International Jazz Festival, June 25 to July 4, fills Quartier des Spectacles with free outdoor stages alongside ticketed indoor shows. Just for Laughs, July 15-26, is the world’s largest comedy festival, having recovered from its well-publicized 2024 financial trouble to run a full program again. Osheaga, July 31 to August 2, closes out the summer run on Jean-Drapeau Park’s island with a multi-day music and arts lineup.
The rest of the year’s calendar
Beyond these six, Montreal’s event calendar keeps going: Fierté Montréal, the city’s Pride festival, fills downtown each August, and the fall brings film and cultural festivals as the foliage turns. None of these carry the same booking pressure as the six above, but they’re worth checking against your dates if the timing happens to line up.
For where to stay around any of these dates, see our full Montreal guide , and for a day-by-day plan that doesn’t depend on festival timing, our 3-day itinerary works year-round.
One concrete tip: if a trip has any flexibility at all, avoid stacking a first Montreal visit on top of the F1 weekend, hotel rates and crowds both spike, and none of the sightseeing itself changes because of it.
