$404 Million in Social Value from GTA Asphalt Harmonization
Municipal asphalt specifications across the GTA were compared under status quo, greater harmonization and further-divergence scenarios.
Headline finding
$404M social value
Toronto Area Road Builders Association (TARBA) · 2025
What the Work Shows
Greater harmonization was estimated to create about $895 million in total value over ten years: $491 million in economic value and $404 million in social value, without new public spending. Further divergence could cost about $990 million, while a slow roll-out would forgo roughly 40% of the available benefit.
A technical procurement standard can have consequences far beyond the paving contract. This case follows those effects through productivity, jobs, businesses and household wellbeing.
A Connected View of Value
The analysis follows consequences through the people affected, compares outcomes across plausible alternatives, and keeps economic, fiscal and wellbeing effects connected rather than reporting each in isolation.
