It really depended upon the "what, where and whens" with the figures. Sometimes different toy stores in the same city would get the same figures, but the packaging from their suppliers could be either US or Canadian.
Back in the late 80's one store I knew of in Vancouver, used to get all US packaged stuff, and another store a block away would get the goods from Hasbro Canada. Sometimes even the same store would get different sourced stuff from one wave to the next.
Woodwards, which used to be a chain up here, would get waves like that.
I do not recall Spirit being named otherwise, but that could be just an example of the different distributed toys.
Only a few of the Joes were given altered file cards up here though, but most of the vehicles sold would have Canadian flag insignia, or both Canada and US flags.
What used to ticked me off what the dual language file cards, which always edited out stuff to accommodate both languages. That's why I always preferred the US sourced stuff myself.
