MONTREAL (Reuters) - Lewis Hamilton won the Canadian Grand Prix for Mercedes in controversial fashion on Sunday after Ferrari's Sebastian Vettel crossed the finish line first but was given a five-second penalty.
Vettel, who started from pole, took the chequered flag ahead of Hamilton but there was no celebration in the Ferrari garage as the furious German was demoted to second after being slapped with the penalty for a dangerous re-entry after running off the track.
