At the 2007 NAPA Auto Parts 200 Nationwide Series race at Circuit Gilles Villeneuve in Montreal, Ambrose was the dominant driver of the day, having led for 37 laps. After a caution period had finished, Ambrose had well-known Sprint Cup regular and Dakar Rally racer Robby Gordon behind him. At turn 3, Gordon successfully made a pass on Ambrose and then the yellow flag came out. At the next corner, Ambrose rammed the left-rear of Gordon's car, spinning him out under yellow. Due to a caution being brought out earlier because of a large crash behind them, Gordon sped back behind Ambrose. During the caution, NASCAR officials declared that Ambrose was actually leading at the moment of caution (even though video footage appeared to show otherwise) and that Gordon had not maintained cautious pace by stopping in the middle of the race-track after the spin. Therefore, officials ordered Gordon to move back to 14th position for the oncoming restart, but he refused and was subsequently black-flagged. When they restarted with 2 laps to go, Gordon intentionally ran into the back of Ambrose at turn 2, spinning him around. Although the win slipped away, Ambrose dropped down the field but recovered to finish in 7th. Following this incident, Gordon apologized and made a peace offering to Ambrose in the form of a ride for the Watkins Glen road race, in Gordon's No. 77 Camping World Ford Fusion. However, qualifying was rained out and the field was set by owner's points, and the No. 77 did not make the race.
