no, not usually, ime. where the tor imprint mmpb printing bears both the u.s. cat# & cover price and a slightly different canadian cat# (with hence a different checksum digit appended) and cover price on the cover, the back cover prices-&-bar-code block bar-code isbn numbers° are usually(/always?) not varied.
this is generally true of other mmpb publishers too, even where the carcass (carcase) of the mmpb is printed separately in canada for the copies distributed north of the parallel - if they share the merkin-printed covers with the wholly merkin-printed copies, the bar-code block bar-code price numbers and isbn numbers are unchanged.
most other mmpb publishers don't have alternate cat#s for canada & canadian-carcassed copies even where they bear two different numerical value cover prices (i.e. quote two cover prices, one u.s. and one canada or can, which is normal now, though it wasn't always so).
i don't know how canadian book retailers and their news wholesalers cope with this - which they presumably do - perhaps the software for the computers recording sales is set to automagically translate to the $.¢ canadian figures (??)
(° - i don't know whether the bar-code itself is identical, as i'm not personally bodily physically equipped to read bar-codes...)
