With captain and fly-half Stephen Jones ruled out of tonight's game after succumbing to his knee injury, Gareth Thomas takes over the captaincy of the Welsh side.
Ryan Jones commented: "We can't afford to start slowly against Canada. We have to set our stall out early and although the boys played some good stuff last week in the win over the Pacific Islanders, we are all fighting for our jerseys. We need to put on a complete performance and a resounding victory is the only way to do that."
Meanwhile, Canada coach Rob Suggitt says his side will punish the Welsh if they focus too much on next Saturday's All Blacks clash. Canada are out for revenge after Wales trounced them 60-3 in Toronto in the summer of 2005.
Suggitt said: "The Welsh players will know that they can't look ahead to the All Blacks game because if they do, it could come back to bite them on the backside. Last time we played Wales we took one on the chin and we definitely want to improve on that performance."
