Its a Regina made by Switson Industries in Welland, Ontario, Canada in the mid to late 1960s. Switson Industries (Later named General Signal Appliances) made similar machines under various names for many different companies.
eg: Baycrest (Hudson Bay Co), Bradford (Zellers), Coronado (McLeods), Eatonia (Eatons), Fairbanks Morse, Mastercraft (Canadian Tire), Regina, Switson, Valliant (Eatons), Viking (Eatons), Watermatic, Waverly (Simpsons).
This is a Coronado model D150 from 1964 (as yours is a D147 it would have been produced around the same time)
All the Switson machines used D prefix model numbers then changed to V prefix when the name changed to General Signal Appliances (The numbers were consecutive though so you can figure out approximate first production date by comparing them to known dates)
Note: Switson also manufactured Kirby in Canada under contract.
