I was lucky enough to find the 12 inch version of this.
The number on the back is "Limited Edition X 13129". I'm assuming that mine is the Australian release.
It has the black and white ballet shoes (same as 7 inch version).
I don't know whether this will help you because I know it doesn't specifically answer your question with regards to the Canadian release, but the catalogue numbers are different so unless they decided to use the same cover on all releases, maybe there's hope yet that you'll be proved wrong.
