Verstappen wins 'crazy' rain-hit Canadian GP ahead of Norris
George Russell, of Mercedes, took third in Montreal.
After the race, Verstappen said: “(It was a) pretty crazy race, a lot happening and we had to keep on top of our calls.
"As a team, we did really well today, we stayed calm - and we pitted at the right time, the safety car worked out nicely for us but even after that we were managing the gaps quite well.
“I love it, that was a lot of fun, those kind of races you need once in a while.”
Norris added: "It was (wild), it was chaos, it was eventful to be honest. I felt like I drove a good race, the whole time, from start to finish.
"The first two stints were strong, I had amazing pace, then the safety car had me over.
"Honestly, I thought it was a pretty perfect race from my side, just a bit unlucky - it was good fun overall."
'That's racing'
Pole-sitter Russell resisted Verstappen before the champion ran wide at turn two and fell within Norris' reach, the McLaren man passing on lap 20, using DRS to sweep by. He then passed Russell on lap 21.
Behind the top four, Alonso in fifth resisted Hamilton before Sargeant crashed his Williams, prompting a safety car intervention. Norris stayed out, but Verstappen, Russell and Piastri pitted for inters, as did Alonso and Hamilton.
As the marshals struggled to remove Sargeant's car, Norris pitted from the lead and re-joined third behind Verstappen and Russell, a harsh setback for the McLaren man.
"The safety car helped me in Miami, but now it held me. It happens, that's racing," Norris, who enjoyed good fortune on the way to his maiden win in May, said after the race.
The race resumed on lap 30 with Leclerc gambling on hard tyres, but as rain arrived again he dropped to 19th. Alonso then ran off and Hamilton surged to fifth, just behind Piastri.
As the track dried, Leclerc pitted again before retiring.
As the other leaders pitted, Norris staying out to pad his lead and build an 'over-cut' before pitting on lap 47.
He took mediums, but as he re-joined Verstappen speared through.
"The ride is bad, like a locked suspension," grumbled the Dutchman with 20 laps to go in dry conditions. "I can't touch any kerbs, it almost knocks me out."
Another crash on lap 54 brought out a second safety car, Albon and a spinning Carlos Sainz tangling after Perez had smashed into the barriers and broken his rear wing.
Mercedes promptly pitted both cars, Russell for mediums and Hamilton for hards. They were fourth and fifth behind Verstappen and the two McLarens when racing resumed and the late drama unfolded.
