England's Justin Wilson won his first Champ Car race at the Molson Indy Toronto on Sunday.
Wilson spent the 2003 season in Formula One
Wilson passed Spaniard Oriol Servia with 11 laps to go and the race ended under caution when Wilson's RuSport team-mate AJ Allmendinger crashed.
The American brushed a wall seven laps out when chasing down Servia and was hit by Mexico's Mario Dominguez.
Canadian Alex Tagliani finished third, while Scotland's Ryan Dalziel came in ninth on his debut.
American Jimmy Vasser wss fourth ahead of France's Sebastian Bourdais, who overcame an early accident with Paul Tracy of Canada to reclaim the lead in the overall series standings.
Wilson said: "The last few laps under caution, I was just hoping it would not go back under green. I wanted to get the first one under my belt."
Bourdais came into the race trailing Tracy by one point in the standings and both started on the front row.
But they crashed into each other following the first round of stops.
Bourdais cut his tyre when he sliced across the top of Tracy's car and had to make a second stop that put him out of contention.
Tracy continued without his left front wing and was leading until he ran out of gas and quit the race.
Bourdais now has a 15-point lead over Tracy, who finished 16th.
Wilson's victory moved him into third in the series standings, 22 points behind Bourdais.
