The third Nations Cup tournament was played at Appleby College and Chatham-Kent in Ontario, Canada, in August 2011 following on from an Under-20 version which took place in California a month before. The tournaments included teams representing the USA, South Africa, England and Canada. England retained both titles.

For USA, Canada and South Africa these were the first internationals they had played since the World Cup. Although the final results in both tournaments were as expected, in the senior event England trailed to both USA and Canada before turning the games round - in the case of the USA game from the final play of the game after 7 minutes of added injury time. Canada led 5-3 at half time in the group game before conceding four second-half tries.

All teams used the group phase of the tournament to try out different formations, selecting their strongest available starting XVs in the finals.
