The idea was conceived by local business and hoteliers to boost tourism during the slower spring and summer periods to the levels they enjoyed during winter’s peak ski season.

The Player’s Quebec Sports Car race in September 1965 would be the first event on the newly-expanded 4.265 km (2.650 mi) track and was won by John Surtees driving a Lola T-70.

Many now famous drivers such as Denny Hulme, Bruce McLaren, Dan Gurney, Jackie Stewart, Bobby Rahal, Chris Amon, Mark Donohue, Roger Penske, Parnelli Jones, Al and Bobby Unser, Gordon Johncock, Alan Jones, Peter Revson, John Cannon, Elliot Forbes-Robinson, George Follmer and Gilles Villeneuve all competed at Circuit Mont-Tremblant during these years.

A CIK-FIA rated karting facility was added in 2010 to complement the Jim Russell Racing School's development of young drivers, and has played host to the Canadian nationals.

New ownership has concentrated on updating the facility to improved FIA standards by repaving and widening the track, expanding the pit lane, and creating greater run-off areas, while attempting to preserve the character of the original layout.

On July 21, 2022 the track complex was purchased by 11938053 Canada Inc.,[1] a company owned by Montreal businessman Gad Bitton of Holand Automotive Group.
