It sounds almost dystopian: One of North America's largest cities handing over a key neighborhood to a tech giant so it can be rebuilt from scratch. That, however, may be exactly what is about to happen. Recently, it was announced that Sidewalk Labs, a division of Google-parent Alphabet, will (pending approval) lead the creation of about a 12-acre district called Quayside in a prime area of Toronto's newly revitalized waterfront area. But if the plan immediately sounds like the beginning of a sci-fi movie in which things are about to go very wrong, Sidewalk Labs' vision at least is distinctly utopian.
