Since the source of the slideshow info is BOC.ca, I'm surprised they'd mix up an image of the 1979 note for the 1969 issue.
Since the INTRO of the "the History of Canadian bank notes" touches on the infamous Hyundai take down of "the biggest counterfeiting ring in Canadian history," I feel they could have added a slide (make a total of #8) with a photo of the first 2001 Canadian Journey $10 (#6 of #8). I expected to see the $10 note at that point- but was surprised to see the $20 there instead.
Ultimately this $10 note (plus computer scanners/high res printers) was one of the reasons there was a record breaking 470 fake notes discovered/million in 2004. The upgraded $20 (preferably slide #7 of #8) was indeed the BOC's remedy to this situation (with the updated 10's & 5's to follow). I suppose this was an embarrassing moment in the history which they preferred to gloss over. Not very objective reporting though.
Also, IMO: the $100 polymer note just looks so much better as an image on a computer screen then it does in real life (where it just appears so drab). The entire slideshow comes off like a pitch for the BOC technological innovations.
