Great questions FF. You and others should be aware that the comments in Canada's nominal national newspaper, the Globe and Mail, were universally opposed to the national team wearing the Livestrong jerseys. To be frank they looked ridiculous wearing them in their first game of the woman's world hockey championships against the USA of all countries.
Since the government of Canada also provides funding to Hockey Canada, it would seem that some disclosure of the Nike deal may have to be released through the government to justify to taxpayers the amount of tax dollars paid to HC.
But in Canada we have a conservative government lacking transparency to begin with, so don't hold your breath! I suspect Hockey Canada are embarassed by the deal but are too proud to admit it.
