The Canadian Grand Prix will be held in late May rather than early June from 2026 as part of Formula 1’s attempts to reduce carbon emissions.
The move allows the Montreal event to be run straight after the Miami Grand Prix, which avoids freight being sent back and forth across the Atlantic.
Montreal will now be held on the third or fourth weekend of May each year, a statement from Formula 1 said.
Since Miami made its debut in 2022, there have been a number of races in Europe between it and Canada.
F1 saw this anomaly as a barrier to its pledge to become net zero by 2030.
F1 president and chief executive officer Stefano Domenicali said: “We applaud the tremendous effort from all involved to accelerate the temporary build of the event, to be ready to host the Formula 1 community earlier than in the past.
“The change will make the future flow of our calendar not only more sustainable, but logistically more sensible for our teams and personnel.
“Our Net Zero by 2030 commitment continues to be a priority for us as a sport.”
Canadian organisers, whose contract runs until 2031, had in the past been reluctant to move their date, arguing that they needed the extra time to prepare the track and environs after the long Quebec winter.
The event also coincided with a wider celebration of the beginning of summer in the city.
But a new promoter, which took over this year, has backed the change.
