Montreal ? Juan Pablo Montoya ended Michael Schumacher’s string of poles at the Canadian Grand Prix on Saturday, leading a record-breaking assault on Circuit Gilles Villeuve.

The 26-year-old Colombian driver sped through the 2.747-mile, 13-turn course in 1 minute, 12.836 seconds, 133.934 mph, easily breaking Schumacher’s year-old record of 1:15.782, 130.494.

In fact, all but one of the 22 Formula One drivers were faster than the previous record by Schumacher, who came into Saturday’s session with three straight poles and six overall on the Montreal track.

Schumacher, the runaway series leader after seven of 17 races, briefly knocked Montoya off the pole midway through the one-hour session, but Montoya came right back out of the pits to regain the top spot for good as he threw his Williams-BMW through the turns with abandon.

Schumacher, 33, goes into today’s 69-lap race with five victories, a second and a third so far this season as he tries to match Juan Manuel Fangio’s record of five Formula One championships.
