(Are your bills still all the same size, or have you
copied everyone
else and made the larger dominations bigger to stop people bleaching
small bills to print big ones?)
Not quite everyone else. Canadian paper money is still all the same
size independent of denomination.
We have, however, recently started issuing new $20 notes (and
presumably higher denominations) with metallic inks and raised printing
and watermark pictures and such that are approximately impossible to do
with consumer-grade printers.
