The gas tax was always set up to be the funding envelope from the federal government that was long-term, predictable, and, importantly, flexible for the needs of local communities.
You've identified correctly that in smaller municipalities large public-transit-specific projects aren't required. In that case, through local democracy, the issues are chosen, like water systems, waste-water facilities, roads and bridges, and other municipal needs.
On the appropriateness of the gas tax, again it's a very significant portion of what is ideally a federal commitment around municipal infrastructure to provide long-term and predictable funding streams. So in that sense the gas tax, in the way it's administered and designed now, is appropriate for the various and diverse needs of municipalities. But as Brock indicated before, it is not indexed, so protecting its purchasing power in the years ahead is something FCM is looking for.
