Is this an modern urban rapid transit system built to serve the city or a ridiculously expensive commuter rail for suburbanites needing views of the river while bypassing 50000+ people?

We could just build a regular Go Transit style comuter rail to serve the suburbs outside the greenvelt (noting that Orleans and Rockland would be more comlicated since they don't have any tracks) and save the rest for a true rapid transit inside the greenbelt like Montreal's dense centre island Metro.
