The Prime Minister has spoken.

In an exclusive interview with Breakfast Television, Stephen Harper told host Kevin Frankish his new book A Great Game: The Forgotten Leafs & The Rise of Professional Hockey was a “diversion” from his political duties.

He also joked that in his three years with Toronto hockey club Leaside Lions, he scored just three goals.

It was Harper’s first Canadian morning television interview for the book, which hit store shelves on Nov. 5.

A Great Game: The Forgotten Leafs & The Rise of Professional Hockey looks at the early days of hockey along with heroes of the sport, business leaders who helped build the game and the never-ending pursuit of Lord Stanley’s Cup.

Harper has called the book, which he spent years researching and writing, a labour of love. This is his first published work on hockey.

Meeting his deadlines was a challenge, he said, and another was the time frame. The book looks at hockey before WWI. In those days, Harper said, clubs didn’t keep records and there was no television footage. But there were newspapers, he said.

All proceeds from the book will go to the Canadian Forces Personnel and Family Support Services.
