But shortly after the news conference Thursday when he said that, a tweet appeared with a photo of him wearing a white Winnipeg Jets jersey while standing next to Winnipeg South Centre MP Joyce Bateman.
The bright red and white Team Canada jersey Harper wore to Wednesday night's game ruffled the feathers of a number of Jets fans and made the prime minister stand out against a background of white.
Harper was speaking at a Winnipeg business, FC Woodworks in Transcona, about his plan to reduce business taxes for small businesses, when reporters asked him about his choice of jersey.
"I'll tell you the whole story," he said. "We were headed out [and] we decided to come out a bit early so we could attend the Jets game at the last minute. So I went up to my wardrobe, going through my hockey room ... and they said, 'Well, you got to wear white.' I didn't have a white Jets jersey. So they threw in the white jerseys [for] when I got there."
But he said he really had only one option when he touched down.
"I opened the case and there were two white jerseys. One was the Team Canada jersey that I wore, and how can you go wrong ever wearing a Team Canada jersey in any city?" he asked.
"But to my horror, I got to tell you this story," he continued. "To my horror, the other jersey they put in was a 1972 Team Canada jersey from the Great Summit Series, given to me and signed by Paul Henderson himself," he said, referring to the battle between Canada and the Soviet Union for hockey supremacy more than four decades ago.
Henderson led Team Canada to victory in that series.
"His jersey— there's no way I'm going to wear a Paul Henderson-signed jersey to the game," Harper said. "So I wore the more recent one."
Harper also paid tribute to the Jets and to their fans, whose support seemed to grow stronger throughout the playoff series despite the Jets losing four straight games to the Anaheim Ducks, knocking them out of the series.
Harper said the team and the fans shouldn't be too disappointed.
"I think it's an up-and-coming team," he said. "The fans last night, the experience, Winnipeggers, Manitobans were just on fire. So look, I think a big hand for the Jets for a successful season and good luck for next year."
