Canada beat the U.S. team 3-2 in a tightly played overtime game Sunday.
Likely to be more visible than the beer bet was one between White House press secretary Robert Gibbs and Harper's spokesman Dimitri Soudas.
Gibbs told Soudas if Canada won he would wear one of the Canadian team jerseys at an on-camera news briefing.
There was no indication when he planned to pay off on the bet, the report said.
