Nearly two years after announcing its intentions to build a high tech "city within a city" along Toronto's eastern waterfront, Google's sister company, Sidewalk Labs, has unveiled a 1,524-page-long draft master plan that's proving every bit as controversial as critics would have led you to expect.

The Alphabet-owned urban innovation firm delivered its overwhelming Master Innovation and Development Plan (MIDP) to the public during an event at its headquarters near the Port Lands in Toronto on Monday afternoon.

To give you an idea of just how huge the collection of documents is, here's what a multi-volume hard copy of the plan looks like:

Sidewalk Labs says it will spend $1.3 billion on building its neighbourhood of the future in Toronto with an eventual goal of creatng some 44,000 jobs, $4.3 billion in annual tax revenues and spurring at least $38 billion in private sector investment by 2040.

Economically, it sounds great, and most people are jazzed about the promise of cool new technologies such as intelligent sidewalks, autonomous vehicles and tall-timber residential developments becoming available within our city.

Those who've had a chance to read through all the of the draft plan's details, on the other hand — chiefly members of the federal, provincial and municipal government-run Waterfront Toronto consortium, who recieved the draft last week — are wary.

Government officials and watchdog groups are already crying foul over everything from how citizen data will be stored to how large an area Alphabet intends to transform.

What was originally pitched as a 12-acre plot of land in what's come to be known as Quayside has reportedly blossomed into a 190-acre "Innovative Development and Economic Acceleration (IDEA) district" along Toronto's waterfront, just east of the downtown core.

"Waterfront Toronto has told Sidewalk Labs that the concept of the IDEA District is premature and that Waterfront Toronto must first see its goals and objectives achieved at Quayside before deciding whether to work together in other areas," reads a sharp press release issued by Waterfront Toronto on Monday morning.

"Even then, we would only move forward with the full collaboration and support of the City of Toronto, particularly where it pertains to City-owned lands."

The non-profit organization's Board of Directors, Stephen Diamond, took care to note in the press release that Waterfront Toronto "did not co-create the MIDP" and that "it is clear that Waterfront Toronto and Sidewalk Labs have very different perspectives about what is required for success."

Among Sidewalk Toronto's big ideas for Quayside, the forthcoming Villier's Island, and other parts of the city's eastern waterfront:

• Thousands of new affordable and below-market housing units in the world's first neighbourhood built entirely from timber.
• A new, Sugar Beach-like public space called Parliament Plaza, more sidewalk space an all-ages playground and "dramatically more" outdoor space that would be accessible year-round thanks to rain and wind-blocking technologies.
• New "mobility innovations" that incorporate light rail transit expansion, pedestrian and cycling infrastructure, as well as "heated bike lanes and traffic signals that adapt to real-time use for safety."
• A global hub for the urban innovation industry that would see Toronto become home to "the most innovation-friendly environment possible."
• A dramatic reduction in greenhouse gas emissions and "a path to the largest climatepositive district in North America" with an 85 per cent reduction in greenhouse gas emissions.
• "The strongest governance regime for urban data anywhere in the world" thanks to the creation of an "independent, government-sanctioned Urban Data Trust that would oversee all collection and use of data from the physical environment."
• A "first-of-its kind profit-sharing arrangement with the public sector" where Alphabet could use the Sidewalk Toronto area as a testbed for its technologies in exchange for giving shares to all three levels of government.
• A new Canadian headquarters for Google on Villiers Island

"This proposal aims to do something extraordinary on Toronto's eastern waterfront," said Sidewalk CEO Dan Doctoroff during a media event for the plan's release.

"Create the neighbourhood of the future in the right kind of way, with people at its centre, and with cutting-edge technology and forward-thinking urban design combining to achieve ambitious improvements in the urban environment and in the way we all live."

Nothing is set in stone, of course. More public consultations still need to take place and neither Waterfront Toronto and the City of Toronto are expected to weigh in with their official decisions on the MIDP until at least the end of 2019.
