MONTREAL (AP) -- Justin Allgaier passed Jacques Villeneuve on the final lap during a green-white-checkered finish and won the Nationwide race at Circuit Gilles Villeneuve, depriving the French Canadian of his first victory at any level in NASCAR.
Villeneuve, who started third, survived three late restarts in a wild race that went seven extra laps and saw Danica Patrick lead 20 laps. But Villeneuve, who had been saving fuel on the track named in honor of his late father, slowed briefly on the final one and Allgaier slid past for his second win of the season and third of his career.
Sam Hornish Jr. finished second and Villeneuve was third, followed by Elliott Sadler and Ron Fellows.
Kyle Busch, who flew in from the Cup race in Michigan to drive his No. 54 Toyota, arrived about 2 hours before the green flag, started at the back of the field because of a driver change, and finished 10th after briefly challenging Villeneuve for the lead with 20 laps left around the tricky, 2.7-mile 14-turn layout.
Patrick led 20 laps and ran second to Villeneuve for another 12 laps before she suffered track bar issues in her No. 7 Chevy after hitting a shoe thrown on track.
