The Bank of Canada is redesigning the notes and they will not be able to be read by the reader starting with the vertical note.
Also the Bank of Canada is recalling a bank note reader that it had recently introduced without much fanfare:
https://www.bankofcanada.ca/banknotes/audience-specific-resources/blind-and-partially-sighted/bank-note-reader-recall/I was told that it was simply reading the colour of the notes unlike the previous readers that were reading a printed code on the bank note.
Someone who tested the reader which was similar to the one that the Bank of Canada is recalling read a coloured paper which was the same colour as the bank note as a bank note of that denomination. I wonder if that is the reason for the recall.
