He dropped out of school at age twelve and worked on his family's farm from 1889 to 1894, when he moved to Montreal.

Georges Gauvreau, who owned the Theatre National before selling it and retiring, attempted to reenter the film industry by buying the Ouimetoscope.

[8][2] Ouimet established one of the first Canadian film exchanges in May 1906, with its first branch office being in St. John, New Brunswick.

He sold Quebec: The Tercentenary Celebration (1908) to Charles Urban and The Eucharist Congress in Montreal (1910) to Butcher's Film Service.

[10] He reentered the industry and formed the Specialty Film Import in 1915, and became Pathé's representative in North America.

Its middling reviews and poor financial performance ended Ouimet's filmmaking career.

Starting in 1943, he and Albert Brault attempted to create a camera that could record separate right and left eye images on the same piece of film.
