The Team Penske driver was challenging Andretti Autosport’s Colton Herta for third on the streets of Toronto when the call came that he should be on the second-to-last lap.
Power was fourth and less than a second behind Herta at the time and passed him a few seconds before entering the pit lane.

A hole-in-one stopped him in his tracks, as the Aussie star finished the race 14th.
Power wasn’t the only driver caught, with Chip Ganassi Racing’s Marcus Ericsson also making a splash-and-dash at the end.
“For Power and Ericsson, it’s amazing,” said IndyCar driver-turned-commentator Townsend Bell.
“Something has gone terribly wrong with the comparison.”
Power wasn’t too happy with the call, making his feelings clear.

The leader of his group said, “We have to make a hole this time to fall in.”
“You didn’t give me a f—— number,” Power yelled.
“Why didn’t you give me the f—— number?
“I don’t know what you’re doing on the f—— stand.”
After the checkered flag, Power came back on the radio.
“If it was F—- easier for me to save some oil, you’d just tell me.
“You got a f—— 1:10s, I wish I had a time of 1:10s. It’s ridiculous. I could get it.”
Speaking after the race, Mr Power said the course needed to be reviewed and given to take some of the blame if he pushed too hard too soon.
Asked after the race if he was surprised by the phone call, Power said, “Yes I was.”
“Give me a number and I could easily find that number and make it,” he said.
“We’ll just have to review all of that. I’m not sure what happened there.
“It was good. The car was great. The track was right. I could have got a really big number and I didn’t know we could.
“If I didn’t get the numbers and attack hard early on it was my fault.
“I was trying to force the two guys in front to fuel them, maybe not keeping a close eye on mine.”
Power wasn’t the only Team Penske driver thwarted by the course.
Scott McLaughlin raced between the top two until just before the halfway mark when the decision was made not to sit under the safety car as most of those around him did.
This made him dry and meant he had to stop under green conditions, which took him out of the top 10.
He eventually recovered to sixth behind teammate Josef Newgarden.
