Force India's practice form deserted Paul di Resta when it mattered most in Montreal, leaving the Scot facing Q1 elimination for the second race running.
Having topped the Friday morning times at the Circuit Gilles Villeneuve, and returned to the top ten in Saturday's truncated session, di Resta was unable to find any time on his last run in the opening phase of qualifying and wound up 17th, the first of those not to progress.
The Scot was joined on the wrong side of the cut by the man who finished third in both of Friday's sessions, Romain Grosjean, the Frenchman making a mistake on his last real effort and winding up 19th. After collecting Daniel Ricciardo in Monaco, however, the Lotus driver was already facing a ten-place grid penalty, and now looks set to start the Montreal race from the very back of the grid.
Along with the two bigger names, the Caterham and Marussia representatives completed those exiting stage left after the opening 20 minutes of a session which started too damp for the slicks that everyone ventured out on initially, but began improving to the point where a dry line appeared on the pit side of the circuit. The return of light rain at the end of the session, however, helped scupper those looking for a late lap.
Sebastian Vettel topped the times after a rapid-fire exchange of places with Lewis Hamilton, Mark Webber, Felipe Massa and Nico Rosberg, who all held P1 for a spell. The other Ferrari of Fernando Alonso eventually wound up second, ahead of Webber, Valtteri Bottas and Massa.
