The oldest of three sons, born in Toronto in 1954, John Massingberd established Promark Motorsport International and Raceline Motorsport Television in the late 80’s to fill a void in the televising of Canadian racing events.

In 1993, he founded, Executive Produced and co-anchored Raceline Radio, Canada’s first nationally syndicated motorsport radio program, featuring Canadian racing talent. Now in its 15th year, Raceline Radio is the most widely syndicated National Motorsport radio program in Canada.

In 1994, John launched SnowTrax Television, which is broadcasted nationally in both Canada and the United States. In 2004, Dirt Trax Television, a companion program focusing on the All-Terrain Vehicle market, was launched and has reached similar acclaim with North American enthusiasts.

His energy, infectious sense of humor and genuine charm is what contributed to John’s larger than life persona. His unique vision, business acumen and strong sense of dedication is what drove him to break new ground in the televising and radio coverage of Canadian motorsport racing and the world of snowmobiling and ATV recreation.

His efforts and legacy have been submitted to The Canadian Motorsport Hall of Fame for induction consideration.

John departed in his 54th year, losing a brief but courageous battle with ALS, Amyotrophic Lateral Sclerosis, commonly known as “Lou Gehrig’s disease”.

He was a very special and valued friend. We consider it an honor to ensure his hard work and success will continue. We've lost a good friend, but John's longstanding friendship with Supertrax serves as a constant reminder of the ‘Big Guy’ who was always a man of his word.
