[1] Auld played in the National Hockey League (NHL) with the Vancouver Canucks, Florida Panthers, Phoenix Coyotes, Boston Bruins, Ottawa Senators, Dallas Stars, New York Rangers and the Montreal Canadiens.

[2] Auld started junior career with the North Bay Centennials of the Ontario Hockey League (OHL) at the tail end of the 1997–98 season, appearing in six games without registering a win.

[3] In his final season, Auld was named to Team Canada for the 2001 World Junior Ice Hockey Championships, where he backed up Maxime Ouellet, winning a bronze medal.

An ankle sprain sidelined Auld during training camp, however, and upon his return, he was assigned to the Columbia Inferno of the East Coast Hockey League.

[9] Following injuries to Canucks goaltenders Dan Cloutier and Peter Skudra, Auld earned a start at the NHL level, a 4–2 victory over the Dallas Stars on January 23, 2002, after which he returned to the AHL.

[13] Auld spent the 2004–05 NHL lockout back with the Manitoba Moose in the AHL, this time pairing with veteran netminder Wade Flaherty.

Despite holding on to the starting role for much of the season, Flaherty took over as starter at the beginning of the Calder Cup playoffs, helping the team reach the third round.

However, on November 20, 2005, Cloutier injured an anterior cruciate ligament (ACL) in a collision with Mighty Ducks of Anaheim forward Rob Niedermayer.

[16] The hope initially was that the injury would heal during the season, but on December 13, Cloutier opted for surgery, leaving Auld as Vancouver's starting goaltender.

[20] In June 2006, Auld was involved in a multi-player trade that sent him, Todd Bertuzzi and Bryan Allen to Florida in exchange for Roberto Luongo, Lukáš Krajíček and a sixth-round draft pick.

As the season progressed, Gerber was placed on waivers[28] and ultimately was claimed by the Toronto Maple Leafs,[29] while rookie Brian Elliott would split the goaltending duties with Auld in Ottawa.

[33] An unrestricted free agent at the end of the season, on July 1, 2010, he signed a one-year, $1 million contract with the Montreal Canadiens as backup to Carey Price, replacing Jaroslav Halák who had been traded to St.

Again an unrestricted free agent at season's end, on July 1, 2011, Auld re-joined the Ottawa Senators, signing a one-year, $1 million contract, replacing Curtis McElhinney as backup to Craig Anderson.
