Mercedes, McLaren bring upgrades to Canada

Mercedes and McLaren are heading to Montreal with new parts on their cars after Miami tightened the fight at the front of Formula 1’s 2026 field. Formula 1 and team previews published on May 18 cast the Canadian Grand Prix as the next major development checkpoint, with Mercedes confirming its first full upgrade package of the season and McLaren also expected to arrive with fresh components. Canada is also the third Sprint weekend of 2026, compressing the time teams have to understand any changes once running begins. ### What exactly is Mercedes bringing to Montreal? Toto Wolff said on May 18 that Mercedes will bring “our first update package of the year” to the Circuit Gilles-Villeneuve. The Mercedes team principal said rivals “took a step forward in Miami and we need to respond,” while adding that performance would only count “once it is delivered on track.” (formula1.com) Mercedes still lead both championships heading into Round 5, according to Formula 1’s race-week preview. Kimi Antonelli’s Miami victory extended his lead over teammate George Russell to 20 points, leaving the Brackley-based team defending an early advantage that looked less secure after Miami.

Lando Norris led a McLaren one-two in the Sprint in Florida, and then fought Antonelli for the Grand Prix win, while Oscar Piastri also finished on the podium. (formula1.com) Formula 1’s preview said McLaren “have new parts to come, too,” putting the team alongside Mercedes at the center of the Canada technical story. Motorsport.com reported on May 18 that both teams are bringing sizable packages to Montreal as Mercedes tries to protect its early-season lead. (formula1.com) ### Why does the Sprint format matter for upgrades this weekend? Montreal is one of six Sprint venues on the 2026 calendar and its first Sprint weekend under the format, Formula 1 and the FIA said when they announced the schedule in September 2025. The previous Sprint rounds this season were in Shanghai and Miami. (formula1.com) Sprint weekends give teams only one practice session before Sprint Qualifying on Friday. That matters for Mercedes, McLaren and any other team arriving with new parts, because engineers and drivers have less time to compare old and new specifications before competitive sessions begin. That is an inference from the Sprint format and the published timetable. (formula1.com) ### What does the Canada timetable look like? Formula 1’s official timetable lists first practice for 12:30 p.m. local time on Friday, May 22, followed by Sprint Qualifying at 4:30 p.m. The Sprint is scheduled for 12:00 p.m. on Saturday, May 23, with Grand Prix qualifying at 4:00 p.m. later the same day. (formula1.com) Sunday’s Canadian Grand Prix is scheduled to start at 4:00 p.m. local time in Montreal on May 24. Formula 1 said the race will run over 70 laps at the 4.361-kilometre Circuit Gilles-Villeneuve. ### What should readers watch once cars hit the track? Miami is the reference point teams are chasing after McLaren, Ferrari and Red Bull all introduced updates there and narrowed the gap to Mercedes, according to Formula 1’s Canada preview. (formula1.com) Wolff said Mercedes’ task now is to answer that step forward while continuing to learn over what he called a long season. Friday, May 22, is the first moment those claims can be tested in public. Mercedes, McLaren and the rest of the field will have one practice session in Montreal before Sprint Qualifying begins later that afternoon. (formula1.com)
