Thank you for sharing this. There are some very interesting design decisions that are evident.
They have continued with what appears to be a full width window along with the metallic stripe.
It appears that they are continuing with the design shift they did with the counters on the face and back with the Canada-150 note.
They have continued with the tactile feature. But are my eyes playing tricks or is the tactile feature reversed. Up until now the raised portion of the tactile feature was on the portrait side (face). Now the raised portion appears to be on the prefix side (back). Of course this would not matter to the a visually impaired person but most certainly it would be noticed by a visually non-impaired person.
It does not look like they have used the magnetic ink feature in this note. Maybe that was the problematic element in Canada-150 which may have caused gaps on those prefixes.
But it seems like they may be back with the frosted maple leaf window.
And while everyone is talking about the special person who is on this note, I think this is the first time I see a recognizable building which is not part of the Parliament Buildings on the bank notes. I think this is the first time the Bank of Canada has given some weight to our urban landscape in such a significant way.
