Canada could use an infusion of infrastructure spending. But, the reality is, we in Ontario are in a lot better shape than most states. While there are some roads that are a disaster, for the most part they are safe and well maintained. We don't have overpasses collapsing on people a la Quebec, or contaminated water pipes like a number of places in the US. Part of that is because our tax dollars actually work for us. Now, the GTA could use a bunch of billions to get better transit...
As for inflation, I would think most people understand that it is essential for growth. Without it, the economy would be stagnate of shrink. One of the Bank of Canada's main jobs is to maintain inflation as 2% annually. Now, I agree, food inflation is outpacing that 2%, and that is obviously not good. But, a lot of that has nothing to do with government spending. Its more an issue of climate change. California, a major agricultural exporter, is suffering from a severe drought. That is pushing up prices, as are other supply chain issues that the pandemic has exposed.
