Should the federal government invest in urban, commuter rail infrastructure?

I don't think it should be a federal government decision, but a provincial or even municipal government one.

it should be provincial. if the project crosses provincial borders, the premiers of both provinces should work together to help build it. The federal government can choose to give aid money if the provincial government(s) asks for it, but only if its a reasonable amount (they are allowed to reject the request).

No, leave this to the provinces but the federal government should have incentives for provinces that invest in commuter rail.

We have alot of transport we can get by and we defenitely dont need to spend more on railway tickets when we already have that thinking years ago in question that was finished, So no.

Transit absolutely needs more funding, but it makes more sense to be on a municipal or provincial level

Yes, but make sure that there is a plan on part of municipal governments, as well as the ridership and tax base to continue funding this project.

The government should invest in commuter urban rail transposition. Trains are a great alternative to using cars. There should be more options to get around in cities such as monorail, train, subway and what not. Cities shouldn't be built around cars it's dystopian.
