"England are very much the team to beat in Women's rugby and playing in the senior side which ran them so close in Holland recently will be a real inspiration," said Stephens.
"We have lost twice to them so far this season in the U20s, but we have some new faces in the squad, some good youngsters coming through and we have a chance to test ourselves again.
"Canada will also supply two teams for the tournament and they will be a tough prospect as well. We haven't had much time to rest on our laurels since the season finished but we wouldn't have it any other way and are all very much looking forward to getting out there now to play.
"The long term aim for us all has got to be the 2010 World Cup, it is certainly a personal aim of mine to be there and we all know we have to perform at this level first to give ourselves the chance of stepping up.
"If we can emulate and even improve on what the senior side did against England this season then we will be on the right track."
