Canada have made two changes to the line-up for their World Cup opener against Tonga in Whangarei on Wednesday.

Ryan Smith starts at inside centre having come off the bench in both warm-up matches against the Americans, while Ed Fairhurst is back at scrumhalf after missing the final warm-up fixture because of work commitments.

Ciaran Hearn and Adam Kleeberger are retained at right wing and blindside flank respectively after coming on as replacements in the first of these warm-up matches.

There are four survivors from Canada's last match against Tonga, a 24-7 victory in their final pool match of the 2003 World Cup.

Jamie Cudmore is again in the starting line-up, this time as a second row, while Fairhurst, Smith and James Pritchard are now in the starting XV having all come on as replacements in 2003.
