From the start, polesitter Herta was unthreatened, while Dixon swept across from the outside to ensure Newgarden couldn’t sneak up from third to claim second. Newgarden checked his momentum and that allowed Alexander Rossi around his outside to try and claim third, but Newgarden had put the matter beyond dispute by the end of the lap. Scott McLaughlin, his teammate, passed David Malukas for fifth, but there was even worse luck for the other Dale Coyne Racing-Honda, that of Takuma Sato who was shoved into the wall at the Turn 1 kerfuffle, and limped his very broken car back to the pits. The debris left behind obliged Race Control to throw the full-course caution.
Following the Lap 4 restart Felix Rosenqvist demoted Malukas down to seventh, while Power had already taken advantage of his alternate tires to move into 12th, from 16th on the grid, but rather than burn up all his push to pass trying to stay ahead of Romain Grosjean who he’d passed on the opening lap, he let the Frenchman back past on Lap 11 and pitted next time by to grab primaries. Defending champion Alex Palou, who had started 22nd, had pitted a couple of laps earlier to take on primaries and such had been his pace, the undercut ensured Power emerged behind him. To avoid the risk of getting jumped should a yellow fall, the leaders rapidly started pulling in, Newgarden remaining ahead of Rossi but now split by rookie Malukas. Herta and McLaughlin stopped on Lap 19, a lap after Dixon and found himself being outbraked by the six-time champion into Turn 1, to effectively take the lead. Behind them, Newgarden and now Rossi were ahead of Malukas, while Rosenqvist had turned in fast enough laps at the end of his stint to emerge ahead of McLaughlin and hold off the Penske driver.
However, Dixon wasn’t yet in the lead, for Graham Rahal, Rinus VeeKay, Pato O’Ward, Jimmie Johnson and Conor Daly had risked running a long first stint on their primaries to try and make a net gain.
Rahal finally pitted from the lead on Lap 25, emerging in 14th which would become 10th once his fellow long runners stopped. Further back, Power was only 19th, and not even threatening the Andretti cars of DeFrancesco and Grosjean ahead.
On Lap 30, Rosenqvist moved ahead of Malukas and onto the tail of future Arrow McLaren SP driver, Rossi, who was applying the pressure to Newgarden while the Penske driver stayed bottled up behind the yet-to-stop Daly.
O’Ward finally stopped on Lap 32, leaving Dixon out front with a 2.5sec lead over Herta, the pair of them in a race of their own as 14sec behind them, Daly continued to hold up a train of cars led by Newgarden, Rossi and Rosenqvist. Finally Daly uncorked the bottle on Lap 36 and pitted.
Not that Newgarden then made any notable progress thereafter because he was in fuel-save mode having been one of the early stoppers. On Lap 43, just past half distance in this 85-lap race, Dixon was 2.3sec ahead of Herta, with Newgarden still 14sec back, with Rossi and Rosenqvist 2sec further back disputing fourth.
That dispute ended in tears on Lap 45, just as Rosenqvist was encouraged by his strategist to make the pass. At Turn 3, the AMSP driver flicked to the inside of the future AMSP driver, and he was fully alongside as they exited the turn but as Rosenqvist floored the throttle his car slid sideways and the contact sent the Andretti car hard into the wall. Race Control would say the attempt was legit and so there was no penalty for the AMSP driver.
The drivers wended their way into the tortuous pitlane, and Newgarden suffered a horrible stop as he stopped too far from his crew, and the refueler struggled to get the nozzle engaged nad Newgarden was down to 11th.. With VeeKay and Daly having stayed out front after their late stops, Ed Carpenter Racing-Chevrolet had a 1-2 – VeeKay on reds, Daly on blacks – ahead of Dixon, Herta, Rosenqvist, McLaughlin, Rahal, Pagenaud, Ericsson and Palou. Following the restart, Newgarden lost out further to Christian Lundgaard and O’Ward.
Up (almost) at the front, Herta was now fully able to stay in Dixon’s wake, but then the yellow flew for debris at Turn 1 – concrete debris, caused by the track breaking up – compressed the field once more.
Following the Lap 59 restart, Ericsson had a couple of wheel banging moments with teammate Ericsson over eighth place but failed to make a move stick. He only had to wait a few seconds to gain eighth anyway, because the yellow had to be thrown once more due to Kirkwood and Johnson coming together at the back of the field and stalling. That yellow saw VeeKay duck into the pits, but because the field had to go so slow through the incident scene, the Dutch driver was able to emerge in 13th despite the field being bunched together.
The next restart came at the end of Lap 66, with 19 laps to go, and into Turn 1, Rahal muscled down the inside of McLaughlin to snatch fourth and the Penske driver got out on the marbles through Turn 2 and lost places to Ericsson, Palou, Lundgaard and Pagenaud. On Lap 69, Pagenaud passed Lundgaard for seventh. Another Penske driver, however, moved forward, getting ahead of O’Ward and Malukas to grab 10th.
Up front, Dixon pulled away from Herta who was having to watch his mirrors for Rosenqvist. Some 1.7sec back, Rahal was fending off the Ericsson vs Palou battle.
In the final 10 laps, Palou eased off from the back of Ericsson, allowing the championship leader to focus on trying to find a way past Rahal. Three seconds further up the road, Rosenqvist’s efforts to get around Herta redoubled, but he couldn’t quite get it done, and he fell half a second short. Ahead of them Dixon scored his first win of the year, after leading 40 of the 85 laps, and ensuring he has now scored at least one win in 18 seasons.
Rahal was great fourth ahead of Ericsson, while Palou can be proud of his charge from 22nd to sixth place, the highest finishing driver of those who had never seen Toronto before this weekend.
Lundgaard was a fine eighth ahead of Penske drivers McLaughlin and Newgarden who completed the Top 10.
