The Monegasque driver, who is fighting Max Verstappen for the F1 world title, was already set for a 10-place grid drop on Saturday as a result of a new control electronics.
However, during the final free exercise on Saturday morning, the FIA announced that Leclerc Montreal would be carrying a number of new power unit components for the remainder of the weekend.
The new internal combustion engine, Turbo, MGU-H, MGU-K is enough to mean that the Leclerc will start from the back row of the grid with AlphaTauri’s Yuki Tsunoda also fitted with a new engine.
Leclerc’s teammate Carlos Sainz also carried a new internal combustion unit, his third and final of the season, so he is not subject to any penalties.
Ferrari’s decision to give Leclerc a new engine for the Canadian GP comes after two failures in the last three races.
He retired from leadership at both the Spanish and Azerbaijan Grand Prix with power unit problems.
In Spain, the issue meant it lost a turbo and MGU-H, while a failure in Baku ensured that the power unit was beyond repair.
Leclerc is moving on to his spare components at this stage of the year, which, coupled with an earlier loss, means he will likely take further penalties before the end of the campaign with more than half the season left.
While Leclerc is disappointed with the recent drop in form, he says the car’s promising pace, which has been once the fastest until recently, gives it an impetus for the future.
“We know the speed of the car. So there’s a sense of confidence in it,” he told Motorsport.com.
“We know that clearly reliability has been a problem in the last three races, but performance has. So we know that whenever we fix those issues, that’s where we will fight Red Bull for the championship.
“I have confidence in this team, because they are giving 200% as usual, obviously, and I am sure that once we fix our issues, we will be able to hold back Red Bull.”
