Coach Kieran Crowley has summoned 36 players for a week-long camp ahead of the Pacific Nations Cup.
"Our aim is to get players going head-to-head to see where the fitness is with the guys," Crowley said in a statement Thursday. "We want to get things in place for the summer and moving forward."
The forwards have been in camp since Monday, with the backs joining them Wednesday.
Crowley will trim the roster and name his Pacific Nations Cup squad Monday. Canada, ranked 17th in the world, opens against No. 13 Japan on July 18 in San Jose before playing No. 12 Tonga on July 24 in Burnaby, B.C., and No. 9 Samoa on July 29 in Toronto.
All six tournament teams — No. 11 Fiji and the 16th-ranked Americans are also in the field — then wrap up play in Aug. 3 in Burnaby.
The Canadian camp roster includes such World Cup veterans as James Pritchard, Ciaran Hearn, Hubert Buydens, Aaron Carpenter, Phil Mackenzie and Tyler Hotson.
But John Moonlight, Phil Mack and Nathan Hirayama are among those missing due to Pan American Games sevens commitments.
Veterans Jamie Cudmore, Jebb Sinclair and Nanyak Dala are currently injured.
Canada will announce its 31-man World Cup roster at the end of the Pacific Nations Cup tournament. The team will then face the U.S. on Aug. 22 in Ottawa and the Glasgow Warriors on Aug. 29 in Halifax before heading to England to play warmup matches against No. 14 Georgia on Sept. 2 and Fiji on Sept. 6.
Playing in a pool with No. 3 Ireland, No. 7 France, No. 15 Italy and No. 18 Romania, Canada opens World Cup play Sept. 19.
