I'd go with Evil Romano on that. In the 70s and 80s, Hockey Canada's influence with the IIHF was the opposite. Officiating back then was entirely Euro-based (stylewise... what's a penalty and what isn't). The old Soviet Union had tremendous influence with the IIHF. Today it's the opposite. More money is made here, hence more influence... and if people don't think that Hockey Canada is above gaining any edge they can, they're underestimating Hockey Canada. Despite the odd mistakes, officiating is almost NHL quality now. 30 years ago Canadian teams were forever punished with penalties that were not consistent with their home leagues in the CHL. NA tournament scheduling are now entirely based upon suitability for the Canadian TV audience, as that's a cash cow. Even the format change from the old straight round robin tournament was changed through the influence of the Canada Cup. The current system of quarterfinals, semis and finals as per today's tournament drives a larger TV audience, and higher gate revenue. A ticket for a gold metal game goes for a far different price than a preliminary game. This wasn't possible with the old round robin format, as a final game might have been meaningless to the standings.
Money holds the leash, in hockey, politics, big business.... everywhere.
