Motorsport.com revealed earlier that both Honda and Ferrari have elected to use some of their token allocation ahead of the race in Montreal.

Ferrari has used three tokens while Honda has elected to use two tokens.

Although Ferrari has declined to elaborate on its exact plans with its upgraded engines, Honda confirmed to Motorsport.com that it will be using the new parts immediately.

It is unclear in which area Honda has elected to use its tokens, but it will likely be revealed in official FIA documentation over the Canada weekend.

Power circuit

Honda’s F1 engine chief Yasuhisa Arai said in Monaco that his company was mindful of the horsepower requirements needed for Canada.

It is those demands that could have prompted the push to bring in tokens earlier than originally expected.

"Canada is a power circuit, so we need more power," he said. "But it is also a heavy stopping circuit, so braking and energy recovery is very important.

"I know that we need more power, but it is not so easy to get that. So it is how to deliver the MGU-K power for that kind of high-speed circuit.”
