Both, really. The old BABN printing of 1872 was used for decades, but such demand as existed was supplied mainly by the chartered banks. See page 88 in Charlton - the $100 denomination was too small to be convenient for bank Dominion note reserves (bank legals of $500 to $50,000 met that need) but too big for the general public, when $100 could well have represented 3 to 6 month's income. The last $100 Dominion note was redeemed in 1918; they are now extinct except as proofs.
