The Vancouver-born Comeau, raised in Meadow Lake, Saskatchewan, was selected by the New York Islanders in the second round (No. 47) of the 2004 NHL Draft. Having played in the Memorial Cup three times with Kelowna of the Western Hockey League, winning it once, the forward arrived in the NHL with a blistering shot, good speed and strong offensive instincts.
From 2006-09, Comeau split time between Bridgeport of the American Hockey League and the Islanders. He made his NHL debut against the Montreal Canadiens on Dec. 7, 2006, the first of a three-game run with New York that season.
