Marconi must have had a regional distribution center in Calgary, of the pre war radios that seem to come up there a large proportion seem to be Marconis. In my area Canadian General Electric and Philco seem to be the big ones with the occasional Canadian Westinghouse (because a local hardware store sold them) the occasional RCA (because a regional music store sold them), the occasional Sparton, Deforest Crosley, and Eaton's Viking.
