A large portion of the payments in New France were made with papier-monnaie [paper money]: letters of exchange, treasury bills, certificates and card money. Each year, the Secretary of State for the Marine sent the currency required to redeem the notes. But the years of war proved costly, and the King of France was slow in making his payments. After the capitulation of Montréal, the inhabitants of Canada were left in uncertainty for several years, before finally, in 1764, the State Council of the King ordered that the paper money be partially redeemed. But actual repayment of the papiers du Canada [Canadian papers] dragged on, and eventually in 1771, the King decided to annul his debts. This resulted in considerable financial loss for Canadians and, to a lesser extent, for the new English occupants.
