Duprée began training in 1955 with Maritime professional wrestling legends Vic Butler and Reggie Richard.
Duprée started in Boston, Massachusetts, and began to travel all over the continent and even went on tours to Australia and New Zealand.
Notable wrestlers who wrestled there include Edge, Christian, Killer Kowalski, André the Giant, Randy Savage, Lanny Poffo, Harley Race, and Ric Flair.
Emile claimed that the promotion ended due to heavy travelling costs.
As of May 2013, Emile and his son René decided to bring Grand Prix Wrestling back to life.
