I haven't the foggiest. Those are questions for an actuary.
I only used the region as example because that was the one I could find the costing for. The data is there to do it for the city streets too and just assume similar costs.
The point about the winter maintenance is a good one. A large percentage of the cost is labour and machinery, both of which are still needed even if the road is narrower.
A really good example of the difference narrowing makes is the essentially parallel streets of Brock St vs. Homewood Ave.
Brock is a bit more than two car widths wide (~5.5m) and there is hardly any speeding. Homewood is only about a metre wider (~6.5m) and they've had to install 3 speed humps and additional speed limit signage (without much effect).

Everyone move to the back of the bus and we all get home faster.
