Ospreys forward Tyler Ardron will captain Canada in the Rugby World Cup.
He is joined in the 31-man squad by Ospreys team-mate Jeff Hassler and Scarlets-bound wing DTH van der Merwe.
Coach Kieran Crowley's team kick off their campaign against Ireland in Cardiff's Millennium Stadium on 19 September.
"Tyler is part of the leadership group at Ospreys and captained them during the Six Nations this year," said former All Black Crowley.
"He's young but will call on the experience of Jamie Cudmore, Aaron Carpenter, Hubert Buydens and DTH van der Merwe, who all have World Cup experience, to help provide leadership."
The 24-year-old Ardron has played 45 matches for the Welsh region and stood-in as captain when Alun Wyn Jones was on Wales duty.
Hassler, also 24, has scored 14 tries in 37 appearances.
Wing Van der Merwe has yet to play for the Scarlets after transferring from Glasgow at the end of the 2014-15 season.
In his final game for the Warriors he scored a try in the 31-13 win over Ulster which saw them lift the Pro 12 title.
Coach Crowley was in the New Zealand squad that won the inaugural World Cup in 1987.
