Montréal club culture has always been hot, and every August îLESONIQ boosts electronic and hip-hop clubbing to legendary summer-festival sonic heights. This year’s festival lineup brings electro stars Alesso, Steve Aoki, Illenium, and many more to Montréal’s sunny shores on August 9 and 10, 2025.

Electro park life

A fierce lineup of widely celebrated artists, high-powered speakers and subwoofers, an idyllic island park, and you: celebrated EDM festival îLESONIQ returns for its 10th season the weekend of August 9 to 10 among the forests and flowers of Parc Jean-Drapeau on beautiful Île Sainte-Hélène, plus a bonus night of music at îLESONIQ IN THE CITY on August 8.

On the heels of indie-rock heavyweight weekend Osheaga, îLESONIQ doesn’t miss a beat with internationally acclaimed artists showcased on three outdoor stages, from early afternoon to well past sunset. While this Montréal festival has made a name for itself first and foremost for its globally recognized electronic talent, its consistently breathtaking audiovisual experiences and impressive stage setups have contributed to its continued draw. Sensory experiences aren’t limited to the stages either, with interactive games, high-tech art, a mini water park, and plenty more activities to stimulate the senses on site. Choose to go for one day of fun, experience the wild weekend in its entirety, or go all-out and treat yourself and friends to one of the festival’s premium experiences.

Eat and drink

While your soul is being nourished by the beat, keep your body nourished by the incredible food trucks and caterers at îLESONIQ — all kinds of food kiosks and gourmet-level food trucks await on site. Grab yourself a tasty burger and classic poutine, a top-tier sandwich, made-to-order pizza, or any one of the treats on offer to give your dancing body the calories it needs to keep going strong. Stay hydrated with water (and plenty of it!) and indulge in a few specialty soft drinks, or some beer and spirits if you’re keen. (Bring two valid pieces of ID to prove you’re over 18!) Water consumption truly is paramount, so bring your own water bottle and be sure to fill it at the water stations onsite. Water bottles should be empty, clear, and plastic.
