Ecstasy to agony for Rosberg in the space of two turns
Here we ride onboard with Red Bull's Daniel Ricciardo, who - from fourth on the grid - had the perfect view of Nico Rosberg's Turn 1 drama at the start. For the first second after the lights went out, it all seemed to be going right for Rosberg. From second on the grid he made a better getaway than Mercedes team mate and polesitter Lewis Hamilton, and had the run on the world champion down into Turn 1. After that though, things began to unravel. First Ferrari's Sebastian Vettel rocketed down the inside and into the lead - and then Rosberg found himself hung out to dry by Hamilton on the outside of Turn 1, a move that had echoes - but in reverse - of the pair's first lap in Canada in 2014. Rosberg tried to stick to the outside for a moment too long, though, and had to take an emergency detour across Turn 2. He still came out ahead of the pack, but was travelling at much slower speed - and was therefore helpless as a multitude of cars, including Ricciardo's, broke either side of him, forcing him down to ninth.
Magnussen has Nasr in a spin
If Rosberg was the main loser in terms of positions in lap one, Sauber's Felipe Nasr took the biggest hit in terms of time. The Brazilian had started 18th, but was pitched into a spin as Renault's Kevin Magnussen tagged his rear through the first chicane - an 'unnecessary' move according to Nasr, but ultimately a racing incident. The upshot? Magnussen gained two places to sit 20th at the end of the lap, while Nasr fell to the back of the field - 4s behind the next car, and already 16s off race leader Sebastian Vettel.
Ricciardo's slip sets up Bottas's podium charge
Most drivers made at least one mistake coming into Turn 13 during Sunday's 70-lap Grand Prix, but not many of them proved this costly - or beneficial, for the man behind. Onboard with Valtteri Bottas, we can see the Red Bull of Daniel Ricciardo - running in third place - a fair way down the road. That is until the Australian gets it wrong at the final chicane, locking up and running over the escape road. He rejoins the circuit in the prescribed manner, but obviously at much reduced speed - reduced enough that the chasing Williams has catapulted past by the time they reach the start-finish line, putting Bottas on course for his - and his team's - first podium finish of 2016.
Perez puts Turn 1 ghosts to rest
Two years ago Sergio Perez was taken out at Turn 1 while fighting for the podium. This year he made an excellent move stick on Toro Rosso's Daniil Kvyat. It might only have been for 11th place at the time, but it would prove decisive in the fight for the final Montreal point - Kvyat was left languishing in 12th, while Perez handed Force India their second straight double-points score as he grabbed the final position in the top 10.
Raikkonen can't hold charging Rosberg at bay...
Both Kimi Raikkonen and Nico Rosberg made two pit stops in Canada. The big difference was how much later Rosberg stopped - his final pit visit (following a slow rear puncture) came on lap 51 of 70, a full 18 laps after Raikkonen's. Hence by lap 57, with the championship leader on a determined recovery drive after picking up damage in his first-corner off, the difference in tyre performance was significant. That, combined with the Mercedes' prodigious straight-line speed, meant the Ferrari was powerless to fend of this textbook pass for fifth place approaching the final chicane.
...but Verstappen blunts the Silver Arrow
Unlike Raikkonen, Max Verstappen had made his final pit call only a few laps prior to Rosberg - hence his defence of fourth place, on ultrasoft tyres to the Mercedes' softs, proved far more robust. Well aware of the looming Silver Arrow behind, Verstappen forces Rosberg to take the outside line into Turn 13 and again protects the inside into Turn 1. Keen to avoid a repeat of his lap-one clash with Hamilton, Rosberg has no choice but to run wide and then slot in behind the Dutchman's Red Bull, before regrouping and planning his next move.
Rosberg throws caution to the wind
Seven laps on, and with the chequered flag rapidly approaching, Rosberg had still been unable to find a way past the feisty Verstappen - and the frustration was starting to show. This time he at least had the speed to pull alongside the Red Bull coming into Turn 13 - only for the rear of his F1 W07 to get away from him as he turned into the corner. The resulting spin was spectacular, though ultimately not costly in terms of position, with Rosberg just about managing to hold on to fifth place from Raikkonen.
Grosjean feels the force
Daniil Kvyat wasn't the only man to fall prey to Sergio Perez coming into Turn 1 in Montreal. In a dress rehearsal of his later, point-winning move, Haas's Romain Grosjean was the Mexican's P10 target on lap 37. Perez brakes late and dives for the inside, before Grosjean sees his chance to switch back as the Force India runs deep and briefly locks a wheel. However, Perez manages to maintain enough speed that the Frenchman's attempts to fight back around the outside of Turn 2 are ultimately fruitless.
