Hamilton delighted after 'sensational' win
Lewis Hamilton said he is ready for the hardest championship battle of his career after leading home a McLaren one-two in the Canadian Grand Prix.
Hamilton leads the standings for the first time this season, three points ahead of team-mate Jenson Button.
He said: "It's the ultimate challenge I've experienced in F1. There are so many of us pushing right to the wire. I think it will remain close all season.
"All the best drivers are in the top teams and are all very competitive."
It was Hamilton's second successive victory and 14th of his career and came on the track where he picked up his first F1 win back in 2007.
With McLaren now 22 points ahead of second-placed Red Bull in the manufacturers' championship, Button admitted he was aware that the race for both titles was by no means over.
Looking ahead to the next race in Valencia in a fortnight's time he said: "I'm sure we'll be competitive, but we can't forget about Red Bull and Ferrari and maybe Mercedes will have sorted themselves out a bit by then.
"I'm looking forward to Valencia. I love the circuit and I think this car should work pretty well there."
Fernando Alonso finished third in Montreal for Ferrari to record his best result since Spain at the start of May, following disappointing results in Monaco and Turkey.
He said: "In Turkey (a fortnight ago) we were a little under-competitive. Here we were fighting wheel to wheel (for the lead) so it's definitely a step forward.
Highlights - Canadian Grand Prix
"We took the opportunity to be in the podium and fight for the win, so it was a positive weekend for us and we are looking forward because I think this result will be a big motivation for the team.
"We did our job here finishing in the podium, something that maybe not too many people were thinking before arriving in Canada.
"We proved we can be very strong and this second part of the championship there is a lot more to come so we are optimistic."
McLaren team principal Martin Whitmarsh admitted he was delighted with every aspect of his team's performance.
"I'm told I sometimes over-use the phrase 'fantastic job' when describing the performances of Lewis and Jenson, but I make no apology whatsoever for using that phrase again today," he said.
Alonso happy with third after difficult race
"This afternoon's race was extremely exciting from a spectacle point of view and decidedly challenging from a strategy point of view, and I think our engineers rose to that challenge supremely well.
"But, yes, Lewis and Jenson did indeed do a fantastic job here in Montreal this afternoon. They drove with controlled aggression when it was needed, tempered by patience and discipline when those qualities were required.
"I firmly believe that Vodafone McLaren Mercedes has the two best racing drivers in the world today. Now, we leave North America and head back to Europe, in first place in the constructors' world championship, and in first place and second place in the drivers' world championship.
"We never under-estimate our competitors, who are working every bit as hard to win grands prix and world championships as we are. There's a long way to go yet, but I can say without fear of contradiction that every single person at Vodafone McLaren Mercedes is working as hard as he or she possibly can to maintain our positions at the top of both championship tables from here on in through to Abu Dhabi in November."
