OSHEAGA is a centrepiece moment of the best things to do in Montreal during the summer. A music festival to many and a rite of passage for others, it's a seasonal staple that brings more than 140,000 people onto Île Sainte-Hélène over one weekend for a three-day marathon of music.
This year? Lorde. Tate McRae. Twenty One Pilots. The xx. Turnstile. Three days of music and unrelenting vibes on Parc Jean-Drapeau. You either prep smart or get swallowed whole.
This guide is for first-timers and seasoned pros alike. Here's everything you need to know to survive (and maybe even enjoy) OSHEAGA 2026.
The basics: When, where, and who
The 19th edition runs July 31 to August 2, 2026, with headliners Twenty One Pilots (Friday), Tate McRae (Saturday), and Lorde (Sunday). Expect 89 artists across six stages, tens of thousands of people a day, and acts ranging from international legends to homegrown discoveries.
