The idea of providing a toll subsidy for trucks on 407ETR during busy hours is being proposed as an alternate to building the GTA West (Highway 413) expressway. An analysis by Transport Action Ontario shows that the costs of such a truck subsidy are less than half the costs of constructing and maintaining Highway 413. Furthermore, due to its better location, 407ETR would also be more useful to truckers, with commensurate benefits to air quality and climate change.
The analysis can be viewed below.
