From the high of Monaco, to the low of Montreal. Charles Leclerc is out of the Canadian Grand Prix.

A twitch for Lando Norris and the McLaren locks up and runs wide. He rejoins the action but he has lost ground on the Mercedes of George Russell and now team-mate Oscar Piastri has gained on the Briton.

The question now is with the rain stopping and the track getting dry again, do we see the same pattern of car performance that we saw in the first stint?

Do we see the McLarens of Norris and Piastri start to come back? If they do so, they are doing so from much closer behind than they were doing in the first stint.

Meanwhile, Logan Sargeant is watching on from the sidelines...

Alpine have gone for it. Pierre Gasly has switched onto the hard compound.

"It's going to be turn one and two again. It's still very wet, everywhere else is drying."

DRS is now enabled and George Russell and Mercedes are debating when the right time will be to switch to the slicks. Lando Norris continues to knock out the fastest laps but oh no, there is a dirty-looking cloud hovering above the circuit.

Yuki Tsunoda and Esteban Ocon are holding firm in the top 10, both drivers still using their starting intermediate tyres.

Below the points scorers, Carlos Sainz is leading a train that includes Pierre Gasly's Alpine and the Red Bull of Sergio Perez.

It has stopped raining here in the paddock but still large dark grey clouds looming around the Circuit Gilles Villeneuve.

Charles Leclerc is trundling along in 19th place, trying to stay out of the way of the likes of Max Verstappen as they pass his Ferrari. The Dutchman, in P1, is over two seconds clear of George Russell and his Mercedes.

With the additional rain the conditions are worsening once more.

The purple stopwatch is a permanent visitor to the name of Lando Norris on the timing tower. The McLaren is chasing down George Russell for second but if he looks over his shoulder he'll see team-mate Oscar Piastri and now the second Mercedes of Lewis Hamilton, vying for his podium place.

Sergio Perez has been absolutely nowhere in this race, he started 16th and is still in 16th.

So Carlos Sainz was involved in a scuffle with Valtteri Bottas and Daniel Ricciardo, which caused a spot of damage to the front of his Ferrari. The incident has been noted by the stewards.

Bottas is one of the drivers who chose not to pit and is now under pressure from those on a newer intermediate tyre.

The front of Carlos Sainz's car comes extremely close to the rear of Valtteri Bottas' Sauber, with the Spaniard running down in 13th place. Max Verstappen up the front, meanwhile, is nearly a second clear of George Russell's Mercedes.

[On Charles Leclerc] The choice to go on to the hard tyre is going to be a very difficult one to follow through, he's so tentative through the first and second turns. It's very heavy the rain now in the paddock.

Williams are one car down after Logan Sargeant's tangle with the barriers so Alex Albon has to do the heavy lifting for the rest of the grand prix. The 28-year-old is brave enough to make a few moves when a gap opens up and now finds himself in the points in ninth place.

Leclerc: "We've got rain."

Engineer: "Copy. Two laps of rain and then it dries, keep it on track and then we'll go fast."

The rain is coming down at a fair rate of knots.
