Harper invited TSN's Gord Miller to 24 Sussex Drive on Wednesday night so he could be filmed watching Game 2 of the Stanley Cup finals.
The prime minister hasn't held a news conference in Ottawa this year, and only rarely stops on the staircase outside the House of Commons to deliver a message to the news media.
His relationship with the parliamentary press gallery is charitably described as frosty.
Last week, he flew halfway around the world to Afghanistan with a planeload of reporters and entertained only three questions during the entire three-day excursion.
But when it comes to hockey, Harper is expansive and accommodating.
The prime minister was also to give Miller a tour of the official residence, and a peek at Harper's extensive collection of hockey memorabilia.
Harper appeared on a TSN Stanley Cup preview program last month, and has also been interviewed on CBC's Hockey Night in Canada this past hockey season.
