Australian Daniel Ricciardo celebrated his first Formula One victory on Sunday in a Canadian Grand Prix that put Red Bull back on top of the podium and dealt Mercedes a first defeat of the season.
An afternoon of high drama at the Circuit Gilles Villeneuve ended behind the safety car after Brazilian Felipe Massa's Williams smashed into the back of Sergio Perez's Force India as they entered the final lap.
Ahead of them, Ricciardo cruised to the chequered flag with championship leader Nico Rosberg second for Mercedes after starting on pole position in what turned out to be a thriller in Montreal.
Last year's winner Sebastian Vettel, the quadruple world champion, was third for Red Bull.
"I'm still a bit in shock," beamed Ricciardo from the podium, where he was interviewed by 1995 Canadian GP winner Jean Alesi. "It's an amazing feeling right now."
Rosberg still stretched his lead to 22 points after team mate Lewis Hamilton, his closest rival, retired with a rear brake problem.

The Mercedes pair had built up a comfortable lead but reported power problems half way through the race, with Rosberg holding out until he was passed by Ricciardo with two laps to go.
"The boy has been brilliant all year," declared Red Bull boss Christian Horner. "It was an incredible drive. It's been a great team effort. We beat them (Mercedes) at the most unlikely track. We are closing the gap."
RED BULL REALISTS
Until Sunday, Mercedes had won every race and finished one-two in the last five.
Red Bull, who won the last nine races of 2013 with Vettel, have been racing to catch up after engine partner Renault started the year on the back foot.
"It's the first time we have beaten Mercedes this year and we managed to get a victory," said Horner. "We're realists, we know we have a massive challenge ahead of us but there is still a long
