Ehh, I live car-free downtown and a 12min walk to the grocery store is my reality.
In fairness, that's like an assertion that biking 20km to work is your reality........
It may well be.........
But it isn't the reality of many others, nor is their desired outcome.
You have to assume people will commute to work, and in a more suburban location, many of their destinations will also be suburban, but not on the subway or GO line.
Likewise, many people do not walk to grocery stores, even in areas where it's highly walkable. There is on-site parking for the Maple Leaf Gardens Loblaws, and for the City Market and Eataly at Manulife etc etc.
Even right next to the subway, a statistically significant portion of customers arrive by car.

To be clear, I am and remain very pro-pedestrian, pro-cycling and pro-transit.
I'm all for discussing ways we can better sculpt existing and new communities to promote that.
But I do think we need to temper expectations on what's feasible in the near to medium term.
As others have pointed out, this would just be the starting condition. A community built sufficiently dense and well-connected to the lands east of the barrie corridor would eventually develop robust retail of its own
Ah, but the bolded is key. People will not give up a second car, never mind a first...........for it will be convenient 5, 10, or 20 years from now. They want convenient on move-in day.
