The night was opened with Canadian Gord Bamford, who thrilled the dancefloor with drinking songs like Is It Friday Yet? and Drinking Buddy, and touched the hearts of parents with slower songs like My Daughter's Father and Little Guy.
Lambert was also joined by the other two members of her country supergroup Pistol Annies, Ashley Monroe, and Angaleena Presley, in the middle of her set.
Dawson Creek was one of only three Canadian stops on her On Fire tour, on the way to the Canadian Country Music Awards in Saskatoon later this week.
