A toll road is a highway where drivers pay fees for use, with tolls funding construction, maintenance, and operations. Tolls may be collected at booths, through electronic systems detecting transponders, or via license plate recognition and billing. Canada has relatively few toll roads compared to other countries—Highway 407 in Ontario is the most prominent example. Toll road debates involve questions about equity (whether lower-income drivers are disadvantaged), congestion management (tolls as a tool to manage demand), and appropriate funding sources for transportation infrastructure. Tolling can generate dedicated revenue for specific roads but shifts costs from general taxation to direct user payment. Electronic tolling has reduced collection costs and delays that characterized traditional toll booths.
