The photos of the heater shows a NY town
And the cardboard box is GM Detroit
So I would suggest it is not a Canadian made heater as most anything manufacturable in Canada had to be back then
That’s why all the tiny brake parts are all marked Canada on them
The heater would not have been special enough to justify the import tariffs
As far as I think I know, the speedometers in the Canadian trucks came from the same USA source and that’s it, maybe
I could be wrong on that.
