I'm not an expert in how the funding in infrastructure agreements works, but I think the normal process would be to agree on a project with the province or the municipality, together with a payment schedule. Progress must be made, but once the agreement is in place and the project starts, the billing will depend on the agreement struck between the province, the municipality, and the federal government. Generally, you'd have some kind of billing process.
