Not that. My 1960s IBM manuals (mostly S/360) all show coding form

OK, .. still not a Canadianism, though. Would seem like a strange
site-specific mod.
Looking at some old docs, it appears it wasn't consistent even within
IBM: an early 60's IBM brochure shows an EBCDIC table in which the
character zero has a slash, in the same table the zeroes in the punch
codes do not have a slash. A 360/370 assembler textbook (Struble/U of
Oregon) has assembler listings with the Ohs slashed and the zeroes
plain.
Are there no IBMers out there that remember whether the dot was in the
middle of the Oh or the Zero in 3270/3278 terminals?
Noper,
they just moved to Canada. ;-) (I dunno if it's really true,
but I remember printing out a page of light bulb jokes from an
individual that worked for EDS Canada (Oshawa, IIRC) (on the IBM
3090 mainframes) and found it odd that the oh's were slashed and the
zeros were not...
Nothing to do with Canada to my experience, more likely an IBMism.
