Ontario toll roads are highways where drivers must pay a fee to use them. These fees help maintain the roads and fund infrastructure projects. The most well-known toll road in Ontario is the Highway 407, which runs east-west and offers a faster route around the Greater Toronto Area. Toll rates can vary based on the distance traveled and the type of vehicle. Drivers can pay tolls electronically using a transponder or through a pay-by-mail system. The use of toll roads can help reduce congestion on free highways, making travel more efficient for everyone.
