There is a reason that when people talk about Grand Prix weekend in Montreal, they do not start with the race. They start with the Ritz.

Every year, on the Friday before the Formula 1 Lenovo Grand Prix du Canada, the Ritz-Carlton Montreal opens its doors to what has become, without exaggeration, the most sought-after social event of the Canadian summer. Not just of race weekend. Of the entire season. A single evening that draws the international jet set, professional athletes, fashion figures, media, and Montreal's elite into one of the most beautiful hotels in the country for a night that manages to be simultaneously black-tie elegant and completely untamed.

I attended last year's edition. I will be attending this year. And I can tell you from experience that what happens inside those doors is unlike anything else the city produces.

What makes the Ritz-Carlton Grand Prix party different from every other event that pops up during race weekend, and there are dozens, from New City Gas to the Maison SI takeover at Windsor Station, is that the Ritz does not just host an evening. It builds an entire world from scratch. Every year brings a completely new theme, a completely new transformation of the hotel's spaces, and a completely new sensory experience. They do not repeat themselves. They do not recycle. They reimagine.

In 2023, it was El Rincon de Havana. The hotel became a Cuban fever dream. Live Latin bands. A mojito bar. Flamenco dancers. A Don Julio 1942 bar. A Louis XIII cigar lounge and casino. A Mercedes-AMG EQS Sedan was suspended in the Ritz Garden. Isaac Delgado, the six-time Grammy award winner, performed with his full orchestra. The guest list read like a who's who of Montreal and beyond: Carey Price, PK Subban, Alex Killorn, Daniel Boulud, boxer Jean Pascal, NBA player Luguentz Dort, Olympic skier Alexandre Bilodeau, television producer Julie Snyder, and NASA engineer Julie Farah Alibay.

In 2024, they turned the entire hotel into a 1950s movie set. The Beatles. Elvis. Marilyn Monroe. A full Beatles cover band. Mercedes Canada and Christian Louboutin built era-specific curated lounges. John Scotti Classic Cars filled the space with vintage automobiles. The Don Julio bar returned. Laurent-Perrier champagne flowed. Capacity was deliberately reduced that year to make the experience more intimate. And it sold out.

In 2025, the transformation went even further. Ritz Royale, presented by Visa, powered by Mercedes-Benz Canada, in collaboration with National Bank of Canada and BFL Canada, took over two full floors of the hotel with a Casino Royale-inspired evening that was equal parts Bond film and fever dream. Laurent-Perrier champagne until 9 PM. An Antonius caviar station. Gourmet food stations from the Ritz-Carlton's executive chef team. DJs Yo-C and Fafa Khan kept the crowd moving until the small hours. Felix Fournier directed the artistic vision. A hidden Mercedes-Benz VVIP speakeasy called Lounge des Icônes was tucked inside the party for a select few, with DJs Yaya and Jacques Greene spinning vinyl in a velvet-draped listening lounge. Holt Renfrew curated fashion moments throughout. Nobu Toronto and Moët & Chandon hosted an intimate pre-party. And on the Sherbrooke Terrace, the Thursday kickoff drew Montreal's most elegant crowd under golden-hour light with curated beats and spritzes while the Mercedes-AMG SL Roadster and GT Coupe turned heads on the street below.

Patrik Laine of the Montreal Canadiens walked the pink carpet with his fiancée. The crowd was black tie from first guest to last call. It was, by every account, the best edition yet.

And now comes 2026.

This year's edition is called Le Bal Interdit: Soirée After Dark. It takes place on Friday, May 22, 2026, at the Ritz-Carlton Montreal, presented by Mercedes-Benz Canada. The Grand Prix itself has moved earlier this year, with the race on May 24, and the Ritz has moved with it, ensuring that Friday night remains untouchable.

The theme is the Seven Deadly Sins. Two opulent floors of the hotel will be transformed into distinct rooms, each inspired by a different sin. Luxure with dimmed lights and slow rhythms. Avarice with excess and opulence. The organizers describe a subtle red-light-district ambiance running through the entire experience. Deep hues, shadowed corners, and the deliberate feeling that not everything is meant to be revealed. It is, in their words, not simply a party. It is an experience reserved for those who understand that true luxury is never advertised. It is discovered.

Black tie is mandatory. Elegance is, as they put it, non-negotiable.

Behind every edition of this event is a team led by Katia Piccolino, the Ritz-Carlton Montreal's Director of Sales and Marketing, and event designer Madeleine Kojakian. Year after year, they deliver what other venues attempt and fall short of: a complete environmental transformation that feels less like event planning and more like world-building. The artistic direction for Le Bal Interdit is by Felix Fournier. The attention to detail is obsessive. The execution is flawless. And the fact that they refuse to repeat a theme, that every single year demands an entirely new creative vision from scratch, is what elevates this from a recurring event into a cultural institution.

What I can tell you from being inside the room last year is this: the Ritz Grand Prix party is not something you attend. It is something that happens to you. The scale of the transformation is disorienting in the best possible way. You walk through the doors of a hotel you think you know and find yourself in a completely different universe. The food is not catered. It is crafted. Ritz-Carlton executive chef-level cuisine served from stations that look like they belong in a film set. The bars are not stocked. They are curated. Top-shelf everything, open all night, with signature cocktails that match the theme. The music is not background. It is architecture. DJs and live performers who understand that they are not filling silence but shaping an atmosphere.

The guest list reflects the gravity of the event. Over the years, the Ritz Grand Prix party has drawn NHL players, NBA stars, NFL athletes, Olympic medalists, celebrity chefs, television producers, NASA engineers, fashion executives, and international media. It is the room where Montreal's social, business, and cultural elite converge with the global jet set that descends on the city for race weekend. And it is, critically, a room with purpose: a portion of all ticket sales supports the Barry F. Lorenzetti Foundation, committed to improving mental health care in Canada.

That last detail matters. It would be easy, and many events do exactly this, to throw a lavish party and call it a night. The Ritz makes a point of ensuring that the evening serves something larger than itself. The glamour has substance beneath it. The indulgence comes with intention.

The 2026 Formula 1 Canadian Grand Prix runs from May 22 to 24 at Circuit Gilles-Villeneuve. The city will be electric. The streets will be packed. There will be parties at New City Gas, at Bord'Elle, on Crescent Street, and everywhere in between. But if you want to understand what Grand Prix weekend in Montreal actually means, what it looks like when a city and a hotel and a moment align perfectly, there is only one room that matters.

The Ritz-Carlton Montreal. Friday night. Le Bal Interdit.

I will be there. Again.
