Justin Wilson took his first pole in the IndyCar Series with a commanding performance in Toronto.
The Dreyer & Reinbold driver cruised through the first two segments of qualifying without even having to use Firestone's softer red tyres - going fastest of all in the top 12 session on the harder black-walled rubber while all his rivals tried in vain to beat him on reds.
Wilson then swiftly produced a 1m00.2710s lap in the Fast Six session to secure provisional pole, and that time proved unbeatable.
Championship leader Will Power was Wilson's nearest rival, just under 0.2 seconds adrift. Power's Penske team-mate Helio Castroneves took third, despite having to park in the run-off at the end of the pole shoot-out.
Ryan Hunter-Reay took fourth for Andretti Autosport, ahead of Ganassi duo Dario Franchitti and Scott Dixon, with Penske's third driver Ryan Briscoe just missing the top six cut in seventh.
Although only Hunter-Reay reached the Fast Six, all four Andretti cars got beyond the group stages, with Tony Kanaan, Marco Andretti and Danica Patrick to start in eighth, 10th and 12th respectively - a significant improvement on the latter's recent road/street course pace.
Alex Tagliani kept up his strong form at home to take ninth on the grid for Fazzt, although fellow Canadian hero Paul Tracy had a disastrous session - ending up 24th for KV Racing after spinning in the first part of qualifying. Vitor Meira (Foyt) crashed at the same time and will start last, while Tracy's KV team-mate Takuma Sato's car came to a halt on track with a mechanical problem, leaving him 18th.
Raphael Matos (De Ferran Dragon) recovered from his morning crash to take 12th, while EJ Viso (KV) - who had been rapid in practice - and returnee Graham Rahal (Newman/Haas) were the fastest drivers knocked out in the group sessions and will share row seven.
