Just to clarify, I know that with the gas tax fund, the federal government does not approve projects. As you say, this is a program to support municipalities' core investments and infrastructure. The funding is transferred from the federal government to the provinces, territories, or municipal associations in certain cases, and then transferred to municipalities, and they decide on projects. You're correct that, as of 2014, there are broader objectives in place, and the gas tax fund is there primarily to support municipalities address their core municipal infrastructure needs.
