îLESONIQ returns to Parc Jean-Drapeau on August 8–9, 2026, marking its 11th edition with a lineup that reads like a snapshot of electronic music’s current power structure. Set on one of North America’s most striking festival sites – surrounded by water, trees, and the Montréal skyline – the festival once again positions itself as a defining moment of the summer circuit.
At the top of the bill are two heavyweights who know exactly how to command a crowd. Dom Dolla makes his return after a run of career-high moments, from stadium shows to global festival domination, bringing his bass-forward house sound back to the island where it’s consistently hit hardest. Chris Lake follows with Chris Lake & Friends, a rare, custom-built set complete with surprise guests and a bespoke Canadian production; less a DJ set, more a statement.
The rest of the lineup is equally deliberate. Canadian favorite deadmau5 anchors the bill with his unmistakable presence and decades-spanning influence, while REZZ delivers her trademark hypnotic intensity. Above & Beyond are tapped to provide the emotional lift, Wooli returns with crowd-tested bass pressure, and AYYBO represents the next wave of high-energy house. Newcomers LYNY and HAYLA signal where dance music is headed, while Boris Brejcha finally makes his îLESONIQ debut with his high-tech minimal sound and unmistakable masked persona.
And because this is Montréal, bass is front and center. Sub Focus, ATLiens, Seven Lions, Layz b2b Kompany, and more ensure the low end hits with authority all weekend long.
Big, loud, and unapologetically ambitious, îLESONIQ 2026 isn’t chasing trends. It’s reinforcing its place as one of electronic music’s most reliable proving grounds.
Full weekend GA and VIP festival passes are available for purchase online.
