Broadly speaking, municipalities are still facing a huge infrastructure deficit. Yes, over the last number of years, in partnership with the federal government and here in the province, we are trying to close that gap, and it is being closed.
Federal investments into the Yellowhead expansion are making a difference, as are federal investments in expanding the LRT system in the city and some of the trade corridor improvements in Edmonton, again, with federal-provincial-municipal partnerships. It's very important that we continue to explore partnerships and clear the way to invest in infrastructure to close that gap.
We have an ambitious goal of electrifying the entire fleet for our public transit. That's close to 900 buses. Canada Infrastructure Bank was helpful for us to initiate that work, and we look forward to that partnership in the future. We also have a huge lead in retrofitting our old buildings to better energy standards as well as repurposing them, maybe for housing to meet that housing infrastructure gap, so I think there's a role for the Canada Infrastructure Bank to play in that area. We have huge issues with our flood mitigation because of climate change, and there have been federal investments in that area. We look forward to working with the CIB in that as well.
There's a lot of potential for municipalities to tap into the billions of dollars that are available that we don't have. As a municipality, we don't have the resources. We have a very limited borrowing capacity, so that's where we want to focus.
