I'll mainly answer the second question, since you already know my opinion on the stability of funding for aging infrastructure.
Green infrastructure has enormous potential. It isn't for a lack of ideas. The goal is to be able to invest and get things rolling in the municipalities. My colleague Mr. Savage talked a lot about public transportation and how to improve it. Population density is a factor. Our small municipality has a population of 26,000, whereas Moncton, the city next to us, has a population of 100,000. Given that we aren't facing the same debt, or even the same deficit, in aging infrastructure, we have the invaluable opportunity to make long-term improvements on our infrastructure. We are therefore in a position to invest substantially in sustainable projects, particularly public transportation. We can also increase population density by getting help to build buildings, such as apartments and condos.
