There are a couple of things.
One of the issues we're hearing about as we work with municipalities on the infrastructure program is that, even though the 10-year program has $181 billion committed—$19 billion of which has gone out the door, which is a lot more than 6%, and even more when you add the gas tax of $2 billion a year and the $5.7 billion on housing—we know that the money is allotted when receipts are received from municipalities.
In other words, we'll grant a $6-million construction approval to a municipality, but if they can't get workers to build it, we don't pay the bills until the bills go out. The money stays in the treasury until such time as a municipality submits a bill. If municipalities aren't getting workers, the project stalls. In other words, the $6 million is still going to be spent, but it won't be spent building stuff until the workers arrive.
How often have you heard about municipalities not being able to find workers and therefore not being able to invoice the federal government for money we've committed to them?
