Confirmed NEW prefix "EAU" on $20 note

New prefix received today. Confirmed prefix this time to ensure correctness.
Prefix: "EAU"
It has been stamped and passed on (no photo, sorry)
Please add "EAU" to system

it will be a while for this one, I am afraid, because that prefix just does not fit the sequence of banknotes being issued by the Bank of Canada (there are no other "EA" notes and the sequence begins at the top of the alphabet, for example, amongst the first banknotes issued in an "EA" sequence would be "EAA"). It really would behoove you to provide some evidence because it may well have been counterfeit.
