Long-term debt refers to municipal borrowing that will be repaid over many years, typically 10 to 30 years, used to finance major capital projects like buildings, roads, and water systems. The extended repayment period aligns debt payments with the useful life of infrastructure, spreading costs across current and future taxpayers who will benefit. Provincial legislation limits how much long-term debt municipalities can carry, usually as a percentage of revenues. Common forms include debentures (municipal bonds) issued to investors. Managing long-term debt responsibly requires balancing infrastructure investment needs against debt service costs that reduce flexibility in future budgets.
