The team won their second straight provincials in 2008, sending them to the 2008 Tim Hortons Brier. On March 13, 2008, Martin's team from Alberta became the first team since 2003 to go through the round robin at the Tim Hortons Brier undefeated. They finished the round robin with a perfect 11–0 win-loss record. They knocked off Saskatchewan 8–7 in the 1 vs. 2 game, and then beat rival and defending champion Glenn Howard of Ontario 5–4 in the final. With that perfect finish, Martin won his third Brier title. Martin finally won his first World Championship at the 2008 World Men's Curling Championship in Grand Forks, North Dakota. After finishing the round robin with a 10–1 win-loss record, he lost to Scotland, skipped by David Murdoch, in the 1 vs. 2 game, only to beat them in a rematch in the final 6–3. This was the first time Kevin Martin won a gold medal at an international curling event. The Martin rink finished the 2007–08 season with two more Grand Slam titles. Due to his Brier and World Championship successes in 2008, the Canadian Curling Association selected Kevin Martin's team (along with Jennifer Jones, Kevin Koe and Stefanie Lawton) to be Canada's representatives on "Team North America" at the 2008 Continental Cup of Curling.
