Career
He currently plays lead for the Brad Gushue rink. As a junior, Walker played for the Charley Thomas Grande Prairie, Alberta rink. Walker was too old to stay with the rink for the 2007 Canadian Junior Championships.
The World Juniors allows curlers to be one year older than the Canadian Juniors.
After Juniors, Walker joined the Kurt Balderston rink as his second. The team missed the playoffs at the 2008 Boston Pizza Cup (the Alberta provincial championship), but qualified for the playoffs at the 2009 Boston Pizza Cup, where they lost to James Pahl.
After missing the playoffs again at the 2010 Boston Pizza Cup, Walker left the team to form his own rink. Walker would do well on his own, and went all the way to the semi-final of the 2011 Boston Pizza Cup, where he lost to Kevin Koe.
After the 2010-2011 season, Walker left Alberta to join the Brad Gushue rink in Newfoundland as his lead.
Walker is employed doing golf course maintenance.
