Roy & Bélanger
I'd love to track down some of the marketing information these companies produced, particularly regarding their distribution. I've seen some Roy refrigerators crop up for sale in the Prairie provinces, but never a Bélanger...
I know Roy also made electric ranges (had one in my 2nd apartment and it was really, really awful...) and I think they had a couple of automatic washers and dryers.
I've seen Bélanger wringer washers, but never an automatic washer or dryer. At one point, they had a line of dishwashers - when I was in high school (pre-1980...) a friend's family had a brand-new one which had to be an Inglis/Whirlpool clone.
And those L'Islet electric ranges were kinda cool - I remember seeing one model where all the surface unit controls were on the top of the control panel backsplash. The guy I knew who had it hated it 'cause he had nowhere to put his salt & pepper shaker!
