Fernando Alonso set the fastest time of FP1 for the Canadian Grand Prix as he edged out the two Mercedes cars.
On a track expected to play to Mercedes' strengths, Alonso set a time of 1:17.238 to top FP1 for the third time this year. Alonso beat Lewis Hamilton by just 0.016s, while Hamilton's team-mate Nico Rosberg was third quickest and within 0.15s of the best time as the top three set times comfortably clear of the rest of the field.
Sebastian Vettel was fourth quickest in the opening session but almost 0.9s slower than Alonso, with the Renault power unit set to be Red Bull's Achilles heel on the long straights of the Circuit Gilles Villeneuve. However, Vettel was still quicker than the rest of the Mercedes-powered cars, with Valtteri Bottas fifth quickest and over a second off the pace.
Daniel Ricciardo ensured both Red Bulls were in the top six as he ended the session 1.2s slower than Alonso, beating the two McLarens, while Kimi Raikkonen and Jean-Eric Vergne rounded out the top ten.
With the circuit in Montreal requiring a good top speed and braking stability, there were a number of instances of drivers running off-track and locking up in the opening session. The close walls also saw drivers trying to control slides on the exit of corners, with only one making contact during the 90 minutes.
Jules Bianchi hit the wall exiting Turn 4, damaging the right rear of his Marussia. It was a relatively glancing blow and Bianchi pulled to a halt at Turn 7 but then was able to limp back to the pits very slowly as the car vibrated due to the damage.
Felipe Massa also had a difficult session as he was limited to just seven laps, finishing FP1 in 17th place ahead of Esteban Gutierrez, the two Marussias and two Caterhams. Alexander Rossi ended his first practice of the year slowest, 0.4s off Marcus Ericsson in the other Caterham.
