Sak, that weird new Maple Leaf background has been in use on Canada Post
stationary cards for several years now. I had a few friends save me theirs as well as checking the local postal counters at PO boxes and got a couple more left behind by persons not wanting them. After talking to postmasters apparently the P.offices did get a sorted variety, but not necessarily all. I now have all 6 english versions. About 13.5 million issued.
Edit: Removed the pictures of Postcards as they are in the link the original poster supplied.
