You sure about that? Because my point was that it's not reasonable expect to win every game of every tournament. Here is a recap for you, try to use your excellent reading skills to follow along:
By my math, Canada has lost something like 23 of 92 WJC games since 2010. That's a .750 win percentage - clearly an impressive winning record. But probabilistically, a .750 team would have, on average, a 13.3% chance of going undefeated in a given 7 game tournament.
Interestingly enough, this seems to be supported by the data, as Canada has only swept the tournament twice in that span (14% of the time).
Even for an elite team like Canada, sweeping back to back tournaments would only happen about 1.8% of the time:

Realistically, we'll probably never see a team sweep 3 tournaments in a row. Heck, as "weaker" nations like Slovakia, Germany, and Switzerland continue to close the gap, we'll be lucky to see 2 consecutive sweeps in our lifetime.
