MONTREAL, Canada - Lewis Hamilton's love affair with the Canadian Grand Prix continued on Sunday as he won the race for a sixth time and slashed Sebastian Vettel's Formula One championship lead to 12 points.

After watching Ferrari sweep to a one-two finish two weeks ago in Monaco, Mercedes hit back with a dominating display as Hamilton cruised to his 56th career win, a leisurely 19.7 seconds in front of teammate Valtteri Bottas.

It was Hamilton's third victory of the season and also his third in a row at the sun-bathed but windswept Circuit Gilles Villeneuve.
