I looked at purchasing a condo in North York up in Ontario a few years back. The condo was connected to a shopping center with grocery, restaurant, movie theatre and other shops. In addition it was right on top of the subway station. At that time I worked downtown in a building also with direct access to the subway as well as to the PATH network. So in this scenario I literally could never go outside and get everything I need, which is both good and bad.

I guess I had something like that in mind but minus the subway so things are in a smaller radius.
