Mail between American and Canadian post offices, which were separated by the Niagara or St. Lawrence Rivers had to be ferried across because there were no existing bridges at this time. From January, 1829, until their termination in March 1837, the Canadian Deputy PMG levied a 2 pence "Ferriage" fee to be added to the appropriate Canadian postage due.
