The urban technology subsidiary of Google parent Alphabet released a four-volume, 1,500-page master plan detailing its intentions for a brand-new neighborhood.

Google's urban-innovation offshoot also said 40 percent of residential units in its Quayside development will be priced at below-market rates, but a housing expert said that won't solve Toronto's housing problems.

The technology partner for the smart city project has been quiet on data storage and privacy issues in the past.

The group released an updated development plan earlier this week that reveals a much smaller development area than what was originally sought.
