No good. I contacted them directly and they don't ship to Canada; or at least not to individuals.

That seems wierd since their web page indicates they do ship internationally and charge for the photo cert where required.

Anyway, you might find a seller on ebay willing to sell you one. A search for 'sunburst canna' yielded the result below. No idea if this seller will sell to Canadians or not, but with a bit of persistence someone there surely will.

Try Claines Cannas out of the UK. Look under contact in the left column and email them to see if they ship to Canada. Good Luck!
