Mercedes arrived in Montreal sitting on an 86-point lead in the Constructors’ Championship, and they brought the biggest upgrade package of the weekend to go with it. It was the Silver Arrows’ first major upgrade push of the season, held back specifically for Canada.

The expectation was that they’d stretch the gap. Instead, McLaren stayed right with them, but team principal Andrea Stella is choosing to treat that as a data point rather than a victory.

George Russell took pole for the Canadian Grand Prix, ending Kimi Antonelli‘s streak of consecutive fastest laps in qualifying, with Antonelli trailing his teammate by just 0.068 seconds to lock out the Mercedes front row.

McLaren answered with an all-papaya second row, Lando Norris edging Oscar Piastri by half a tenth.

Under two tenths separated the McLaren and the lead Mercedes – a gap Stella describes as “encouraging” given the context of what Mercedes brought to the table.

He was clear in post-qualifying interviews that McLaren also came to Montreal with upgrades, but the team made a late call to pull back one key piece.

A new front wing had been tested by Norris throughout Friday’s sole practice session, with Piastri also trialling it mid-session, but McLaren reverted both cars to the previous spec for sprint qualifying after it failed to deliver the expected performance gains.

In other words, the gap to the front was held while effectively running the Miami car.

There’s More Coming, and Stella Isn’t Hiding It

“We also had upgrades to the MCL40 and I don’t wan to miss any opportunity to thank the team for the efforts in bringing these upgrades,” he said. “There’s a little bit more that hopefully we will take to the coming races, especially there’s a couple of items that we will review for the future races. So like I say it’s very encouraging the trend.”

The Canadian package already covered substantial modifications to the floor, chassis, bodywork, front and rear wings, halo, and roll hoop – a sizeable haul even before factoring in that the headline front wing piece was effectively benched for further study. The fact that McLaren is sitting on additional parts they haven’t committed to yet suggests the development conveyor belt from Woking is still running hot.

The plan, as Stella laid out ahead of the North American swing, was always to deliver what amounted to a completely new car across the Miami and Canadian rounds.

A double DNS in China and a slow start to the season left the reigning constructors’ champions scrambling to get to grips with the new power unit architecture.

The trajectory since then has been sharp.

Whether the straight-line deficit Stella acknowledged – McLaren’s strong corner performance bleeding time on Montreal’s long straights – becomes a factor in Sunday’s race depends partly on weather. Rain is possible, and as Stella noted after qualifying, “everything is possible so we’ll certainly do our best.” The forecast alone might shuffle the deck before any of the development math comes into play.

Seven-time world champion Lewis Hamilton is in danger of losing his fifth place in Canadian Grand Prix qualifying for impeding Pierre Gasly.

Hamilton is set to face the FIA race stewards one hour after qualifying for allegedly blocking Alpine driver Gasly at the Circuit Gilles Villeneuve. On his first flying lap in Q1, Gasly encountered Hamilton - who was on an outlap - on the run down to Turn 8. Hamilton appeared unaware of Gasly approaching as he weaved to warm up the tyres before Gasly was able to find a way past. The FIA stewards are now set to investigate if the Ferrari driver's actions warrant a grid penalty.

Hamilton qualified fifth in Q3 behind the leading cars from Mercedes and McLaren, as he is set to share the third row with Red Bull's Max Verstappen.

Gasly ended up in 14th in Q2 as Alpine team-mate Franco Colapinto advanced to Q3 to take 10th on the grid. Gasly had struggled all weekend with the behaviour of his car, taking his Alpine out of parc ferme after sprint qualifying to use Saturday morning's 23-lap sprint as a glorified test run.

Aston Martin driver Lance Stroll is also set to face the stewards for allegedly impeding Audi's Nico Hulkenberg in Q1. Cadillac's Sergio Perez is also heading to the steward's office for an incident with Aston Martin driver Fernando Alonso, with the Spaniard also speaking to the stewards for a potential unsafe release out of the garage.

Mercedes driver George Russell claimed pole with a last-ditch effort, beating team-mate Kimi Antonelli's time to claim his second pole of the 2026 season. McLaren's Lando Norris and Oscar Piastri will line up on the second row on Sunday, when wet conditions are a realistic possibility.

F1 Canadian GP: George Russell beats Kimi Antonelli to last-gasp Canada F1 pole

Although Kimi Antonelli believed that he was pushed off the road at Turn 1 by George Russell in their battle for the lead of the Canadian Grand Prix sprint race, the Formula 1 stewards did not see fit to intervene.

Russell maintained position on the inside of Turn 1, with Antonelli attempting to make a move around the outside. However, the Italian found his car in a rapidly closing gap and was forced to take to the grass to avoid contact.

However, Antonelli's stance was evident over the radio; he felt that he had his wheels sufficiently alongside Russell's car to be granted room for the inside of Turn 2, in deference to F1's driving standards guidelines. 

Was he right to be aggrieved? Let's take a look at those guidelines and see whether Antonelli's point of view is justified.

The guidelines differ for overtaking around the outside and the inside. If a driver is taking the inside line, these are as follows:

"Overtaking on the inside of a corner

To be entitled to be given room when overtaking on the inside, the overtaking car must:
i) Have its front axle at least alongside the mirror of the other car prior to and at the apex.
ii) Be driven in a fully controlled manner particularly from entry to apex, and not have “dived in”.
iii) In the stewards’ estimation, have taken a reasonable racing line and been able to complete the move whilst remaining within track limits."

Antonelli stated that he had his front axle in a reasonable position alongside Russell and his argument over the radio hinged on this - but in the first instance into Turn 1, he must refer to the guidelines that cover outside moves.

"Overtaking on the outside will always be viewed as a more difficult manoeuvre to accomplish. To be entitled to be given room, including at the exit, when overtaking on the outside, the overtaking car must:
i) Have its front axle ahead of the front axle of the other car at the apex.
ii) Be driven in a controlled manner from entry, to apex, and to exit.
iii) Be able to make the corner within track limits."

Antonelli was alongside Russell on the approach, and the two appeared to be level at the apex, but the stewards may well feel that Antonelli's axle was crucially not ahead for anything beyond a split second. GPS data then shows that Russell lifts off slightly to maintain some of the momentum to ensure his front axle remains ahead into the corner.

With Turn 1 and 2 in such close proximity, Antonelli may well argue that he was attempting to prise open an overtake into Turn 2, in which the inside-line rules would apply; in that case, his axle was beyond the mirror. Yet, he was already off the circuit at this point before the change in steering direction.

Regardless, this has already been covered in the following part of the guidelines, which states: "The above guides for inside and outside may apply for each element of the combination. Generally, priority will be given to the first corner element."

While Antonelli may have a case if the inside-line guidelines applied, the difference in guidelines for an outside pass thus changes the picture, even in the event of an S-bend. 

It depends how much weight the stewards place on Antonelli being marginally ahead at the apex for a fraction of a second, and whether this was indeed measurable in the moment.

The 2026 Canadian Grand Prix Sprint at Circuit Gilles Villeneuve was, for most of its running, a Mercedes affair.

George Russell converted Sprint pole into victory, with Kimi Antonelli going off the circuit twice during their intra-team battle and dropping to third behind Lando Norris.

For the reigning world champion in the McLaren, he was waiting for the Silver Arrows’ race to come crumbling down.

Norris crossed the line 1.272 seconds behind Russell in second place, but his post-race analysis of the result said more about McLaren’s approach than the gap itself.

“It was good just to watch them go at it for a little while,” Norris said. “But of course we were just there to pick up the pieces when things happened and… they were quick. I mean, Kimmi caught me back up pretty quickly and then I was pretty worried from behind, but also I wanted to try and attack George ahead. So, it was fun.”

McLaren Was Quick – Mercedes Was Quicker

Russell came into the weekend 20 points behind Antonelli after the Italian teenager won the last three Grands Prix, and Montreal is clearly a circuit he wants back.

Mercedes’ upgrades for Montreal put them further ahead of the field , and it showed. McLaren locked out the second row, but the pair were over three tenths behind Russell in sprint qualifying. McLaren team principal Andrea Stella acknowledged the gap plainly, per Sky Sports F1:

“I think it’s a fair margin considering they had important upgrades here. We also had some upgrades. We actually wanted to take a bit more time to see the behaviour of the front wing, so we raced with the previous front wing. So, looking at the fact that the car is pretty much the Miami car, it’s a gap that remains encouraging.”

Lewis Hamilton struggled with tyre degradation in the closing laps, losing positions, while Oscar Piastri crossed the line in fourth for McLaren, just ahead of Charles Leclerc. Hamilton eventually finished sixth.

The phrasing of official communications from the FIA’s stewards tends to be deliberately dry and factual, but a note of schoolmasterish anger was manifest in the document announcing and explaining a €30,000 fine for Racing Bulls after Liam Lawson’s breakdown forced Formula 1 practice to be red-flagged in Canada.

Lawson’s car halted with a hydraulic problem within 10 minutes of the sole practice session for this sprint weekend getting under way, but the marshals were unable to move it.

That in itself presents a problem at the Circuit Gilles Villeneuve, an older venue that doesn’t have the space to accommodate the perimeter roads expected of newer tracks, complicating the task of removing stricken cars.

Even so, since all cars must be fitted with a so-called Clutch Disengagement System (CDS), which acts even if the onboard hydraulics and electrics have failed, it should have been possible for the marshals to push the VCARB 03 into one of the gaps in the barriers while covered by a virtual safety car (VSC) deployment. Instead, the session had to be red-flagged, and race control added five minutes to the end of the session to compensate.

For breaching Article C9.3 of the FIA F1 Regulations, Racing Bulls was fined €30,000, €20,000 of which was suspended for 12 months “subject to no further breach of this regulation by the competitor, for either of their cars”. This brings an element of peril for the team, since it has emerged that FIA technical delegate Jo Bauer has previously warned Racing Bulls about its CDS design, which is unusual in that it also services the car’s anti-stall system.

Article C9.3 states: “All cars must be fitted with a means of disengaging the clutch for a minimum of 15 minutes in the event of the car coming to rest with the engine stopped. This system must be in working order throughout the competition even if the main hydraulic, pneumatic or electrical systems on the car have failed.”

Liam Lawson stopped on track in the sole practice session for the Canadian GP

The system is activated by a button that must be clearly marked, and located facing upwards on the monocoque so it can be reached and activated within five seconds by the driver or marshals. As reported in the stewards’ findings, in this case the marshal who initially tried to activate the CDS was trying to press a button in the wrong place.

But this had no bearing on the outcome, because the system had failed anyway – and this is what clearly annoyed the stewards. Not only did the dual function design prevent the car from being moved, disrupting the business on track, it created a further safety hazard in that the CDS is also supposed to shut off the car’s electrical energy recovery system.

“It was noted that the system on this car performs two roles,” said the stewards’ statement.

“The one for which is it primarily intended, namely to release the clutch when the car is stopped and the engine is not working, and the other relates to the anti-stall system. In this case, a ruptured joint caused a hydraulic leak, which caused the car to stop.

“The CDS, when activated by the marshal, then failed to release the clutch and hence the car could not be moved.

Liam Lawson, Racing Bulls

“This is a serious matter. It resulted in the session being red-flagged.

“Had the system worked as intended by the regulations, the incident could have been dealt with swiftly via deployment of the virtual safety car.

“The stewards note the concern of the FIA technical delegate, over the dual purpose of the CDS on this car. The technical delegate advised that the team had, in 2025, been warned about the CDS system design for its cars.”

Making a single component perform more than one role is a solid engineering principle but in this case, it resulted in an expensive fine and a verbal slap on the wrist from the stewards. The wording of the regulations doesn’t explicitly forbid the CDS being used for more than one purpose, but it’s understood the technical delegate’s concern related to the additional complication making failures more likely.

The choice facing the team now is whether to redesign the system – if possible, given its integration into the anti-stall mechanism – or take the risk of it happening again.

Following the significant progress made in Miami, the opening day of the race weekend in Canada proved more challenging for Red Bull. Max Verstappen had to settle for seventh place in sprint qualifying, just ahead of team-mate Isack Hadjar.

During the second segment of sprint qualifying, Verstappen had already complained over the team radio and returned to the pitlane early, despite sitting in the danger zone in ninth place at the time.

A seventh-place starting position for the third sprint race of the season is not what Verstappen was looking for, although based on his feeling behind the wheel he had not expected anything different.

“I'm not surprised. I mean, my feeling in the car was not very good. I was struggling a lot with just the ride of the car,” Verstappen said after sprint qualifying.

“So, all over the bumps, I couldn't put my foot down. Actually, my feet were even flying off the pedals. It just made it very difficult to be consistent and that's something that we need to investigate.”

Attacking the kerbs is traditionally a key factor at Circuit Gilles Villeneuve, and according to Verstappen that is precisely where he is currently losing a significant amount of lap time.

“That was not great. So, of course, we are stuck with that for the sprint, but yeah, some other things to understand and hopefully that will be done a bit better for qualifying.”

Max Verstappen, Red Bull Racing

Parc fermé will be opened once more before the main qualifying session, meaning Red Bull can theoretically still turn its weekend around. According to technical director Pierre Waché, the team at least has some ideas about what needs to improve.

“We saw a direction to go in, but putting the tyre where we want it to be was quite difficult. Sprint qualifying didn't go as we had hoped. We had an issue with Max where car performance deteriorated as the session went on, so we need to understand that.

“I think we had more performance available to us, but we just weren't able to extract it today.”

Pirelli has indicated that the Montreal circuit offered very little grip on Friday and that drivers found it difficult to get the tyres up to temperature, which also explains why almost everyone completed two flying laps on the softs in SQ3.

For Red Bull, the focus is on two things: getting the tyres into a better operating window on Saturday and solving the ride issues so Verstappen and Hadjar can push closer to the limit.
