Thank you very much, Mr. Julian, for both those questions. I'll take them in order.
To your question on the necessity of significant investment in infrastructure on an ongoing basis, certainly the communities you're referencing in your part of the country are not alone in looking to really advance transit system expansions, in continuing to grow their public transit systems and in doing a lot of work to that end, using, where they can, the gas tax fund transfer dollars and also the public transit fund dollars. Our recommendation is, quite clearly, to continue to double-down on the direct investments to municipalities in the areas of infrastructure through a tool that gives that long-term predictability municipalities can plan against, like the gas tax transfer, but also to implement the commitment that we saw from the federal government in the last election around a permanent transit fund on an ongoing basis.
The current plan will sunset in 2027. There is a commitment to make the public transit fund permanent, which would give municipalities across the country the certainty they need. Part of what was so significant about this transit fund, which we would recommend continue on an ongoing basis, is that it was allocation-based. Systems across the country were aware of what their allocation was, what it was going to be for the foreseeable future, and were then able to plan long-term transit expansions, like what we're seeing happen out west, which is significant.
We believe that there is a necessity for continued and significant investment in infrastructure in the country, with a particular emphasis, from our perspective, on the necessity of its being predictable and as long term as possible, and allocation-based to provide that kind of certainty to communities.
To your second question, we agree with IBC. We watched its testimony with interest and have done some work together to try to continue to assess the impact of new weather extremes and climate change on communities across the country. Municipalities are on the front lines, both in terms of being the owners and operators of this kind of infrastructure for which there is a significant dollar bill attached to upgrades to be more resilient and to adapt to climate change, but also in terms of response. As we see more floods, as we see fires continue, it's the municipalities that are on the front lines dealing with these new kinds of weather extremes.
Our recommendation, specifically, is to continue to invest in the disaster mitigation and adaptation fund. It was heavily oversubscribed in the previous iteration. We know across the country that the demand far outstrips the dollars that are available. Our recommendation is to increase it by a further $2 billion over the next four years, because the risks are real and we are seeing them unfold in communities across the country. The necessity to upgrade infrastructure to be more resilient is critical.
