Do you know that the province shelled out to build the 427 alone? Officially $1.6 billion but perhaps up to $100 billion when you include the cost of acquiring all the land. Even if the $100 billion is a bit of a stretch, it cost an astronomical amount of money to build the highway systems--the tolls on that road only pay for its upkeep. Gas tax doesn't even begin to cover what is spent on the road infrastructure.Have you seen how much gas is taxed?
Especially in a place like Toronto, which doesn't get any of the gas tax...
