Thanks to its win over Tonga at the Rugby World Cup, Canada has moved up three places to No. 11 in the world rankings.
It's the highest Canadian position since the International Rugby Board began regularly ranking teams in 2003.
Tonga, which lost 25-20 to the Canadians last Wednesday, dropped three places to No. 15.
Canada lost 46-19 to fifth-ranked France on Sunday, a loss that will be factored into next week's rankings.
Canada takes on Japan on Sept. 27 in Napier, New Zealand. The Japanese remain 13th in the rankings.
In other changes, Australia fell one spot to No. 3 in the wake of its loss to Ireland. South Africa moved up to No. 2, behind New Zealand.
Ireland climbed two spots to No. 6. Wales and Scotland fell one place each to No. 7 and 8, respectively.
Moving up were Italy (No. 10, up one), Fiji (No. 14, up one), the U.S. (No. 17, up one), Namibia (No. 19, up one) and Portugal (No. 20, up one).
Going in the other direction were Samoa (No. 12, down two), Romania (No. 18, down one) and Russia (No. 21, down two).
