Yes it is! Thank you very much, that fills out the Canada Post
rod222 - your's is Philatelic Exhibition Cards #1 - set of three printed by AP, BABN and CBN.
FYI - These are included in the SCCS numbering system as semi-official cards: SO-6, SO-7, and SO-8. You will find a number of other Canadian cards in the Semi-Official category -- http://www.souvenircards.org/gallery/SO/SO.html
And while we are on the subject, there is another Canadian card we are planning to add to the SCCS catalog, which slipped through the cracks 20 years ago! This was produced by Canadian Bank Note for Royal Royale in 1998. I would love to get a better scan if anyone has one. (Both sides if there's anything on the back.)
