[English form of the name used by French-Canadian firm,] see Compagnie d'Orgues Canadiennes.

The Canadian Pipe Organ Co. was located in St. Hyacinthe, Quebec. The Casavant historian Simon Couture writes:
In the [twentieth] century, the Compagnie d’orgues canadiennes/Canadian Pipe Organ Company, founded in St. Hyacinthe in 1910 by two former Casavant employees, J.N. Daudelin and Ludger Madore, was quite active until 1930. As far as I know, this firm built mainly relatively small tubular organs. The chancel organ at St. Roch Church in Quebec City is in my opinion the best example of this company’s work.
