I have a mid '60s Snap-on box (KC 532) and it was made in Canada. I'm pretty sure that it was made in Toronto (Mimico / Long Branch) but I don't know for sure.
There's more info in the
What's up with canadian SO tools thread from a couple of years back...
In 1946, the manufacturing plant was in rented premises in Long Branch, ON (in the most south-west corner of Etobicoke). I'm not sure if this was the first year at this location or as a manufacturer in Canada.
In 1951, a brand new company-owned building housing Manufacturing & Canadian Administration was built at 41 Cranfield Road, Toronto. This remained the plant address until 1967.
I
believe the HQ and manufacturing then moved to the Concord location at 8271 Keele Street (even though this location was already occupied by Snap-on from 1956) in a building now occupied by
Clover Tool Manufacturing. I know Snap-on was still present at this location in 1979.
I do not know what occurred after that...
Here's some dates I've compiled as I was planning an article on the topic...:
