Gillis was hired by the Canucks in April 2008.
"On behalf of my entire family, I would like to sincerely thank Mike Gillis for his hard work and the many contributions he made on and off the ice during his tenure," Francesco Aquilini, chairman of Canucks Sports & Entertainment, said in a statement. "The Vancouver Canucks had success under Mike's leadership, and we nearly reached our ultimate goal. But I believe we have reached a point where a change in leadership and new voice is needed."
Under Gillis, the Canucks reached the Stanley Cup Final in 2011 and won the Presidents' Trophy in back-to-back seasons (2010-12). Gillis won the GM of the Year award in 2010-11. The Canucks were knocked out of the playoffs in the first round each of the previous two seasons, winning just one game in the process.
