Just a precision, based on what I heard, I
assumed there will be a totally new serie, and that they won't just upgrade the actual banknotes. I'm translating you a part of the interview so you can judge for yourself.
Starting at 6:22 in the interview, here's what Mr. Lebeau says :
"[...] en 2011, on va émettre une nouvelle série qui sera plus sécuritaire. C'est la condition ultime pour la Banque du Canada, d'émettre une nouvelle série. C'est pas une coquetterie qu'on a de changer le design des billets [...] donc en 2011, vous devriez voir apparaître une nouvelle série de billets de banque qui vont être, on l'espère, encore plus sécuritaires."
translation...
"[...] in 2011, we will issue a new serie that will be safer. It is the ultimate condition for the Bank of Canada, to issue a new serie. We're not being fancy by changing the design of the banknotes [...] so in 2011, you should start seeing a new serie of banknotes that will be, we hope, even more secure.""New serie", "change of design"... I assumed this ain't just an upgrade of security elements.
I wonder if they would dare making different sizes for every denomination?
Or go ahead an create the 200$ banknote...
