I didn't know they made Whites in Canada, I only knew about their Cleveland factory. I know they stopped production there right about '55, when they started just importing and badging machines. Mine is from '51, I have the manual and receipt for it.
By the way, a big part of these machines is getting good traction between the motor drive pulley and the balance wheel. If the pulley is intact but hardened, you can fresh it up with sandpaper, if you need a new one this one will fit:

Do you live in a log cabin? Looks beautiful, I'm a city guy but I'm fascinated by rustic living.
