Lewis Hamilton reclaimed top spot in the second practice session at the Circuit Gilles Villeneuve ahead of teammate Nico Rosberg.
Sebastian Vettel was in third after a late run saw the German set a 1:16.573 ahead of both Ferrari drivers.
Once again, Kevin Magnussen was the first man on track setting the early pace ahead of DaniIl Kvyat.
The Williams drivers of Felipe Massa and Valtteri Bottas exchanged times at the top before Nico Rosberg restored order by setting the quickest time of the session.
Adrian Sutil was the first man on the super-soft tyres however was blocked by Kevin Magnussen at the final chicane which resulted in no action being taken from the stewards.
Jules Bianchi’s day went from bad to worse as his car suffered an engine problem which left the Frenchman with only three laps on the board.
Marcus Ericsson’s session was also stopped early as he suffered a transmission problem which forced him to stop his car at turn three.
Hamilton set the fastest time of the weekend on the super-soft tyres which was only one tenth clear of Rosberg.
Felipe Massa set the sixth quickest time with teammate Bottas in seventh. McLaren were comfortably in the top ten once again.
Force India have struggled so far this weekend and look set to struggle to qualify in the top ten on Saturday afternoon.
The final thirty minutes of the session consisted of long runs where the teams tested the durability of the tyres – it remains to be seen whether teams will opt for a one-stop or two-stop strategy.
