The 25-year-old Leclaire is coming off his best season, going 24-17-6 with a 2.25 goals-against average, .919 save percentage and nine shutouts in 54 games. He ranked second in the NHL in shutouts, seventh in GAA and 11th in save percentage. Leclaire's record was the best in franchise history and his shutout total nearly doubled the previous club mark of five set by Marc Denis in 2002-03.
After the season, Leclaire helped Canada win a silver medal at the world championships, going 4-0 with a 2.00 GAA and one shutout in four games.
"He is an important part of our team and we think he will continue to improve and play a significant role in helping us reach our goals," Blue Jackets general manager Scott Howson said.
Leclaire, the Blue Jackets' first pick and No. 8 overall in the 2001 draft, owns a 41-49-11 record with a 2.71 GAA and 10 shutouts in 113 career NHL games. He missed most of the 2006-07 season with a knee injury.
