Sebastian Vettel was the fastest man in the third free practice session at Canada, edging out his team mate Kimi Raikkonen by 3 tenths. Lewis Hamilton followed in third spot but saw both Ferrari's ahead of him for the first time this weekend.
Just like in previous race weekends, Ferrari seem to have unlocked a bit of additional pace, and again slightly more than Mercedes appeared to have found. Underlining this fact is Max Verstappen who managed to split the Mercedes by setting a lap on the ultrasofts that was a close match to Lewis Hamilton's best effort.
Behind Bottas in 5th, Nico Hulkenberg emerged 6th, ahead of Felipe Massa and the second Red Bull of Daniel Ricciardo.
The session was generally much cleaner than FP1 and FP2, with no spins and hardly any off-track moments. Perhaps the most important observation was Hamilton's effort on the super soft tyre, which ended up at 1m 13.516s. Given that yesterday's times appeared to indicate around a second of difference with the ultra softs, the Briton's performance was perhaps slightly better on that tyre than his eventual best effort on the purple ultra soft.
Qualifying will show the true differences later today...
