Blue Jackets general manager Scott Howson announced the deal on Tuesday night.
The 26-year-old Letestu has one assist and two penalty minutes in 11 games with the Penguins this season. He had 14 goals and 13 assists and a plus-4 rating in 64 games with Pittsburgh last season and ranked fourth among NHL rookies in game-winning goals (three), seventh in power-play goals (four) and tied for 11th place in goals.
The Alberta native was signed by Pittsburgh on March 22, 2007, after he spent one season at Western Michigan.
Life's about opportunity and how you respond to that opportunity, and obviously he must have some swagger about him, some confidence about him, because he was solid. He made some good saves. He was 6-foot-3 on every shot, which is a good thing for a goalie. He played well. We got a win.
— Maple Leafs coach Mike Babcock on rookie goaltender Garret Sparks, who made 24 saves in his first NHL start, a 3-0 win vs. Oilers
