There are old numbers in terms of the overall infrastructure deficit: $123 billion is the number dating back to 2007. We did not update those numbers; we focused on the efficiencies of having upgrades to our infrastructures today rather than waiting until the end-of-cycle costs that are incurred. Those are 10 times more expensive than upgrades earlier on in the process.
All of this is to say that we are at the edge of infrastructure that is aging. Most of our infrastructure was built in the 1950s and 1960s. Municipalities own about 60% of the infrastructure in Canada. We are tasked with replacing and upgrading the infrastructure that is now at or near the end of life cycle. If we don't make near-term investments today, the costs to do replacement will be significantly higher than to maintain it. It's not dissimilar to road infrastructure. Rather than replacing a road, if you fix a road it's about 10 times cheaper.
