I'll play. Given the timelines involved (and the horrendously expensive obstacles to overcome), by the time this becomes real - if it ever does - it would mean that the Portlands over by Cherry Street and Villiers Island would already have become much more built out and thriving with residential, commercial and the like. Given that, it would be reasonable to expect lots more amenities around than is the currently the case. People around the world tend to favor living close to the water and this is a prime stretch of Lake Ontario right here in the GTA.... proximity to exercise and nature on the Leslie Spit, proximity to the Lake Shore and Gardiner.... it's a far better prospect than most people would imagine. Transit, however, is an open question - and in this town, a lack of transit is becoming a real point of contention for shiny new builds.
In any case, right now? Nawww. It's pretty isolated and forlorn down there. Let's see what happens over the next decade. Cleaning up and revitalizing the Hearn would be a colossal task, requiring obscene amounts of money. But would I live consider living down there? Oh yeah, I sure would.
