"\ {0,1}(\d[ABCEGHJKLMNPRSTVWXYZ]\d)$"
seem to work as it is.

Thanks for that, but this is a perfect example of an API use instead of
other methods of checking postal code validity. I haven't mentioned a
few things because I didn't want to become involved in a long session of
e-mail about their postal codes.
There is a lot of confusion in all these areas in Canada, not the
least of them being the law-suit over the "list" copyright being
violated so much. I pretty much at this time consider Canada Post to be
the "bible" for information, as loose and lacking as their information
is. It's pretty clear why the general concensus is to use A-Za-z for the
alpha part of the codes.
For instance, in a few pages on their site, it says "New Postal
Codes are added every month." but nowhere is there any information on
what's been added or where either.
And, a lot of postal zones have created their OWN postal codes,
without the blessing of Canada Post, and they work just fine because
that particular area is known to that office and thus delivers to it.
They're even trying to trade-mark "Canada Post" according to more than a
couple sources, meaning no one carrying their "list", meaning those
carrying their "lists" couldn't say that's where the codes originated.
Lot of miscellaneous wrong-headedness is going on too but I have to
draw the line and be realistic.
That I can find the post doesn't evein indicate the need for the
space in the postal code. Looking at their images sure isn't definitive,
at their website, that is. And at one time it started to be a dash, then
reverted to a space again, and so on.
This is probably the last I'll have to say on this subject. suffice it
to say I settled on all letters and all digits with a space in the middle.
Regards,
Twayne`
