Not to just be a huge buzz-kill but there are some potentially serious legal issues here.
You should read the PDF policy document on use of bank note images posted here:
http://www.bankofcanada.ca/banknotes...mages-gallery/
And take note that there is a specific defence to the criminal offence if the printed likeness of the bank note is shown to have "length or width...less than three-fourths or greater than one-and-one-half times" of the actual bank note
and the likeness is black and white only or is printed only on one side.
I don't want to see people getting in trouble over something with obviously the best of intentions. Especially where the Bank's policy seems to indicate it is prepared to make exceptions to its rules for educational purposes if permission is sought.
