Russia outplayed Canada by a small margin. Canada got much better goaltending.
Caveat on Russia outplaying Canada
Its hard to tell if Russia would've dominated play for so long in the 2nd period if Canada didn't break out to a 5-1 lead. Also, Ref called chintzy penalties on Canada and none on Russia.
Some casual observers claim Russian hockey is in decline. In the past 5 years Russia has been the best team in this tournament. Also, Russia's juniors come over to North America to play in the "Subway Series" against the OHL, WHL and QMJHL. They play great in this event as well. Russian hockey is alive and well.
with respect to the finns, swedes, and americans...
the best hockey games ever played are Russia/U.S.S.R. versus Canada... and the score is 6-5 or 5-4.

Congratz to Canada; they never trailed in the 2014 Olympics and now they went the entire 2015 World Juniors while never trailing. 39 goals for... 9 goals against over 7 games.
Mike Babcock and Benoit Groulx deserve a lot of credit for the above mentioned 2 accomplishments.
