Russell had been leading in Montreal following a tense battle with teammate Kimi Antonelli before suffering a sudden power unit failure on Lap 30.
The Briton was visibly furious after pulling over at the side of the circuit, throwing his headrest onto the track and banging his car in anger before climbing from the car.
The incident quickly spread across social media, prompting a response from Red Bull’s official X account underneath a fan post showing Russell tossing the headrest away.
“Borderline something something,” the team replied.
The post was widely interpreted as a reference to Russell’s explosive feud with Max Verstappen during the closing stages of the 2024 Formula 1 season.

Tensions between the pair escalated after qualifying for the Qatar Grand Prix, where Verstappen received a grid penalty for impeding Russell.

The fallout intensified a week later in Abu Dhabi, when Russell accused the Dutchman of reacting with “borderline violence” when things did not go his way.
“As soon as something doesn’t go his way, he lashes out with unnecessary anger and borderline violence,” Russell said at the time.
The FIA stewards investigated the Mercedes driver after deeming the act of throwing his headrest unsafe, ultimately issuing Russell a €5000 ($8100 AUD) fine suspended for 12 months.
That means the penalty will only be enforced if Russell commits a similar offence over the next year.
In their report, the stewards confirmed Russell had apologised and admitted embarrassment over the incident.
“The driver explained that he was extremely frustrated having failed to finish the race, and expressed his embarrassment at what subsequently followed,” the report stated.
“He apologised to the stewards for his action and acknowledged that it did not set a good example and offered to apologise publicly.
“The stewards acknowledged this and accepted his apology.”
Russell later publicly apologised to marshals and FIA officials on social media.
“Apologies to the marshals & FIA for making their job harder than it needed to be,” Russell wrote.
“Lots of emotions in the moment.”
Russell’s retirement handed victory to Antonelli, who claimed his fourth consecutive grand prix win and extended his championship advantage over his Mercedes teammate to 43 points after five rounds of the 2026 season.
