Final laps and controversy

With 29 to go, Niclas Jönsson took the lead after Carpentier pitted. With 27 to go, Jönsson pitted and gave the lead to Marcos Ambrose. But Jönsson's chances of winning vanished as he had a catch can violation and had to do a drive through. Ambrose was looking for his first ever win in all of NASCAR in his 23rd Busch Series start which would be perfect for him since Ambrose was a veteran at the road courses after he drove in Supercars from 2001–2005. But with 17 to go, Jorge Goeters spun in turn 1 and would eventually bring out the caution for the 3rd time when his car stalled in turn 2. During that time, his teammate at Brewco Motorsports Greg Biffle went off track in turn 10 and into the gravel traps but was able to get his car going with no incident. The race would restart with 13 laps to go with Ambrose leading. At around 9 to go, two incidents occurred. The first being when Patrick Carpentier spun in turn 2 after contact with Brad Coleman with the second being when Scott Pruett spun in turn 10 while racing with Ron Fellows. With 8 to go, the 4th caution would fly when Boris Said's engine blew. Before the caution, Robby Gordon made his way up to second passing Fellows which had a chance to see two road course veterans in Ambrose and Gordon battle it out. The race would restart with 4 laps to go. But on the restart, the controversy would begin. The 5th and final caution would fly for a 6 car crash in turn 2 when Kevin Harvick came up into Scott Pruett after Pruett made contact with Harvick in turn 1 almost sending him off the track and Pruett spun up into Ron Fellows and both of them spun. The wreck also collected Ron Hornaday, Jeff Burton, and Brad Coleman after Hornaday and Coleman went too far off track off of turn 1 and ended up running into the pile up. Meanwhile, Robby Gordon battled Ambrose for the lead. Before the caution flew, Gordon had passed Ambrose for the lead and was ready to slow down for the caution after they went through turns 3 and 4 but Ambrose got into the back of Gordon off of turn 4 and turned Gordon around during the caution. An angry Gordon would speed back up and catch up to Ambrose and showed his displeasure by hitting him in the door during the caution. The wreck would set up a green-white-checkered finish extending the race by a lap. But during the caution is where controversy ensued. NASCAR's rule states that "when the caution comes out, the field is immeadietly frozen" which means whatever position the cars were at during the caution stays in that position. The rule was implemented at the end of the 2003 season. The rule also had that "if you don't maintain pace car, speed you lose your spot" which wouldn't be for Gordon since he got intentionally spun out by Ambrose during the caution. This means Robby Gordon should be the race leader. But for some reason, NASCAR said Robby Gordon did not maintain pace car speed and should be placed back in the 12th position (Robby later said he was forced to go back to 17th). It confused a lot of people as they saw Ambrose dump Gordon during the caution and thought Gordon was the leader. Instead of listening to NASCAR, Robby Gordon refused to go back and decided to keep his car in the second position behind Marcos Ambrose. That should have been a black flag by NASCAR. Instead, NASCAR decides to throw the green flag and restart the race with Gordon still holding his car in the second position. Eventually, both Ambrose and Gordon went through the first turn and Gordon would be able to get his revenge on Ambrose as Gordon get into the rear of Ambrose, turned Ambrose around in turn 2, and ran off towards the sunset with the lead, or so he thought. Instead, NASCAR decided to disqualify Robby Gordon and not score him for the last two laps after 73 laps ran by Gordon and said Gordon is not the leader which meant the car that was behind Gordon on the restart in Andy Pilgrim was the new leader. Eventually, Pilgrim would get passed by Kevin Harvick for the lead after Pilgrim got loose off of turn 3. Harvick had a challenger in Niclas Jönsson before Jönsson got loose and got passed by Patrick Carpentier for second. Carpentier tried to pass Harvick in the last two laps but couldn't and Kevin Harvick won the first ever race in Montreal and Carpentier finished in second. Max Papis, Ron Fellows, and Stephen Leicht rounded out the top 5 while Kyle Krisiloff, Marcos Ambrose, Brad Coleman, David Reutimann, and Jeff Burton rounded out the top 10.^[3]

Despite being scored in 18th, Robby Gordon decided to do burnouts with Harvick claiming he was the race winner even though he was disqualified. In his interview, Gordon quoted "If you want to know my opinion, I won the race. I completed all the laps, and if you seen this happen before, guys get spun out when they slow down that's exactly what happened with Marcos. He spun me when I slowed down, and they tell me I'm gonna back to 17th. It's not the way it is. It's happened many times– they set the precedence before, and we'll appeal it. We won the race." NASCAR suspended Robby Gordon for the Cup Series race at Pocono the following day replaced by P. J. Jones, fined $60,000, and placed on probation until the end of the year. Eventually, Gordon would make it up to Ambrose and allowed Ambrose to attempt to qualify for the Watkins Glen Cup race the following week in his No. 77 RGM car which Ambrose failed to make. In 2010, Gordon announced he was going to compete in the Montreal race and he also announced he decided to make himself a banner and a makeshift trophy similar to the one from the race to claim he won the 2007 NAPA 200. When asked about how he was going to recover in that race, Gordon chuckled and said "You mean since I won? We've still got the banner hanging on our wall. We came back for redemption, and we'll do the best job we can."^[4][5]
