2026 Ontario Honda Dealers Indy at Markham Results

Marcus Ericsson started the inaugural Ontario Honda Dealers Indy at Markham in fourth and withstood the chaos to win for the first time in nearly four seasons. Ericsson led 21 of 90 laps, including the final five and captured his fifth NTT INDYCAR SERIES victory (101st drivers with at least five victories), fourth on a temporary street circuit and first with Andretti Global in his third season with the organization, who earn their 79th INDYCAR victory.

Andretti Global now has multiple drivers with a victory in one season for the first time since 2022.

The Kumla, Sweden-born driver also took victory at the inaugural street race in Nashville five years ago.

The Andretti Global driver, who snaps a 63-race winless streak (St. Petersburg 2023), held off Dale Coyne Racing’s Romain Grosjean by 7.5305 seconds on the 2.19-mile, 12-turn street circuit in Markham, Ontario. Grosjean now has six runner-up finishes but has yet to reach victory lane during his INDYCAR career,

Will Power climbed from 25th to third, earning his third podium of 2026, matching his best finish of 2026 in third and bookending the podium at Markham for Andretti Global. Chip Ganassi Racing’s Alex Palou finished off the Top Four sweep by Honda-powered entries and extended his points lead to 133.

Arrow McLaren’s Pato O’Ward led Chevrolet in fifth after starting in 23rd due to a late engine change and subsequent penalty. Despite running out of fuel on the final lap, Grosjean’s teammate Dennis Hauger finished 15th and holds onto the Rookie of the Year lead by 31 points with four races to go in the 18-race NTT INDYCAR SERIES campaign.

Recap

Foster began to distance himself from the field shortly after the green flag at the alternate start line by Turn 6. Further back on the grid, Caio Collet’s weekend saw another tough break. During the opening lap, the A.J. Foyt Racing rookie punctured tire and toe link damage. Meyer Shank Racing’s Felix Rosenqvist also would suffer a puncture that led him to an early pit stop following the contact.

Collet would return to action but finished 23 laps down in 19th.

On Lap 15, the race would come to an early stop for Mick Schumacher, as Foster’s RLLR teammate made heavy contact with the outside wall in Turn 4.

Meyer Shank Racing’s Felix Rosenqvist fell out of the race with a fuel pressure issue shortly after the Lap 19 restart. Collet would get back on track but was 17 laps down.

On Lap 31, his MSR teammate would see his day unravel as well. Marcus Armstrong stalled and spun in Turn 5. Armstrong would later be given a 10-second stop-and-hold penalty for not following instructions from the AMR Safety Team. While Foster and the other leaders had not made their stop, the ensuing cautions mixed up the running order.

Nolan Siegel and Romain Grosjean shuffled up to the lead ahead of the Lap 36 restart. Soon after, the “cautions breed cautions” adage rang true again. After contact with Hauger, Scott Dixon would spin in Turn 8 and Christian Rasmussen was collected, ending the Ed Carpenter Racing driver’s race, while Dixon would head to pit lane.

Siegel led the field back to the green flag on Lap 40 but was quickly overtaken for the lead by Grosjean. After making a bold pass on Ericsson for third, Foster skirted into the outside wall inTurn 3, ending his day with a massive impact to the outside wall on Lap 43. Foster climbed from his car but his day ended after leading a career-high 32 laps, most of anyone this afternoon.

Grosjean would hold the lead through the ensuing restart on Lap 54, when he pitted from the lead. Kirkwood had a similar crash to Foster in Turn 3, resulting in another caution. Kirkwood finished 21st but still remains second in points.

Ericsson. led at Lap 60 but the carnage would continue further back in the field, as Siegel and Newgarden made contact in Turn 5, resulting in an another caution. Siegel would also be given a drive-through penalty for the avoidable contact.

On Lap 70, Ericsson made his final stop of the day and would give the lead to Grosjean. Grosjean’s fuel-save got him to the end of the race but Ericsson would take over the lead with four laps to go and held on to become the seventh different winner (matching 2025’s total) in the 2026 season.

Five drivers swapped the lead a total of seven times during the 90-lap race, which featured six cautions for 25 laps. The average speed of the first race at Markham was 83.156 mph.
