McLaren is set to unleash a sweeping upgrade package at the Canadian Grand Prix, with new components spanning seven distinct areas of the MCL40 as the Woking outfit doubles down on an aggressive development push that began in earnest at the Miami Grand Prix.
The team has confirmed new parts covering the floor, chassis, front and rear wings, bodywork, halo and roll hoop for this weekend's race at Circuit Gilles-Villeneuve — mirroring the scale of the seven separate updates it debuted in Florida.
"As established at the beginning of the season, Miami served as the first big step in our plan to add performance to the MCL40," the team said ahead of the Montreal round. "This continues this weekend in Montreal, with a number of new components across the floor, chassis, front and rear wings, bodywork, halo and roll hoop."
The most eye-catching addition is the rear wing, which is believed to represent McLaren's interpretation of the so-called "Macarena" wing concept — a design detail that will draw considerable attention in the paddock. For a deeper look at how McLaren's technical thinking evolved through Miami, this breakdown of their Miami Grand Prix upgrades provides valuable context on the aerodynamic direction the team has been pursuing.
The timing of McLaren's update makes the Canadian Grand Prix a pivotal moment in this season's development race. Mercedes deliberately withheld its first major upgrade package from Miami — unlike McLaren, Ferrari and Red Bull, who all brought significant developments to Florida — in order to concentrate its firepower on Montreal. The Silver Arrows now arrive at Circuit Gilles-Villeneuve with their own headline package, setting up a direct performance shootout between the two title contenders.

The stakes are underscored by comments from McLaren team principal Andrea Stella, who acknowledged that Mercedes held a two-tenths-per-lap advantage in Miami. The team will be hoping that its double upgrade push — combining the foundations laid in Florida with the new Montreal specification — can either close that deficit or, at minimum, neutralise whatever performance gain the Silver Arrows unlock this weekend.
McLaren arrives in Montreal with genuine confidence after a strong performance in the Sunshine State. Lando Norris and Oscar Piastri secured a sprint one-two in Florida, and both drivers reached the podium in the grand prix itself, finishing second and third respectively behind Mercedes' Kimi Antonelli.
Despite that, the reigning constructors' champion finds itself third in the standings with 94 points — 16 points behind second-placed Ferrari and 86 adrift of championship leaders Mercedes. The urgency to find performance is clear.
"The competition in Miami was close, but the team secured a sprint 1-2 and a double podium," McLaren said. "The team is recharged after the two-weekend break from racing and is prepared to carry this momentum into the next North American round at a track favoured by many drivers."
With both McLaren and Mercedes now bringing major development packages to a single venue, the performance swing at Circuit Gilles-Villeneuve could prove genuinely decisive in how the constructors' championship unfolds over the coming months.
