A budget shortfall occurs when projected revenues are insufficient to cover planned expenditures, creating a gap that must be addressed before a balanced budget can be approved. Shortfalls may arise from declining revenues (economic downturns, reduced provincial transfers), rising costs (inflation, contractual wage increases), or new expenditure pressures. Municipalities must close shortfalls through some combination of revenue increases (tax hikes, fee increases), expenditure cuts, or drawing on reserves. Addressing shortfalls involves difficult choices about tax impacts versus service reductions. Early identification of shortfalls allows more time to develop thoughtful solutions rather than rushed crisis responses.
