The machines were made at the CAMCO (Canadian Appliance Manufacturing Company) plant in my native town of Montréal, Québec. I could drone on for ages about the differences and subtleties of the Canadian-built appliances, but to try to sum up, it was done to be able to offer them at a lower price to the Canadian market (there were tarriffs and duties on items imported from the USA back then and these were added to the retail price).
