Ottawa summers just aren't complete without a good fireworks show, and this year the sky over the Ottawa-Gatineau region is about to get a serious upgrade. The 29th edition of Les Grands Feux Casino Lac-Leamy kicks off on July 29 and runs through August 15, 2026, bringing its signature pyromusical spectacle back for another season of dazzling summer nights.
What Is Les Grands Feux?
For those unfamiliar, Les Grands Feux is one of the region's most anticipated summer traditions — a festival that combines world-class fireworks displays choreographed to music, creating what's known as a "pyromusical" performance. It's the kind of event that draws crowds from both sides of the river, with Ottawa residents crossing over to Gatineau to catch the show, or simply finding a good vantage point along the Ottawa River to watch the sky light up from home.
More Than Just Fireworks
While the fireworks are obviously the main draw, this year's festival promises to be more than a one-note spectacle. Organizers are packing the event with family-friendly programming, immersive experiences, and a lineup of local food vendors, making it an easy full-evening outing rather than just a quick show-and-go. Whether you're bringing the kids for an early evening of activities before the sky show starts, or just looking for a solid excuse to grab dinner along the water, Les Grands Feux is built to keep people entertained well beyond the actual fireworks.
Why Ottawa Loves This Festival
For Ottawa residents, Les Grands Feux has become a rite of summer passage right up there with Bluesfest and Winterlude — proof that some of the best entertainment in the National Capital Region doesn't require crossing an international border, just a provincial one. The festival's cross-river appeal means it draws a genuinely mixed crowd of Ottawa and Gatineau locals, all gathering along the waterfront or from balconies and rooftops across the city to catch a glimpse of the show. It's also a reliable go-to for anyone hosting out-of-town visitors who want to see something quintessentially Ottawa-Gatineau during their stay.
Plan Your Visit
With the festival running for nearly three weeks, there are plenty of chances to catch a show even with a busy summer schedule. Locals who've been before know that arriving early for a good spot along the river pays off, especially on weekend nights when crowds tend to swell. Pack a blanket, grab some snacks from the on-site vendors, and settle in for an evening that's become one of the Ottawa area's most reliable summer traditions.
