1 Dollar = 5 Shillings

The Niagara Suspension Bridge Bank was never a functioning financial institution in any conventional sense — it was a wildcat bank, chartered in Upper Canada but operating near the U.S. border specifically to exploit the gap between American and Canadian banking regulations. Queenston, sitting at the foot of the Niagara Escarpment just above the river, was chosen for its jurisdictional convenience, not its commercial importance.

The dual denomination — one dollar equated to five shillings — reflects the chaotic currency arithmetic of pre-Confederation Canada, where American dollars, British shillings, and Halifax currency all circulated simultaneously, often at contested rates. A bank willing to print both units on a single note was positioning itself for cross-border use by design.

No record of this institution holding meaningful specie reserves survives.
