Greber Plan

The General Report on the Plan for the National Capital (1946–1950), or Gréber Plan, was a major urban plan developed for Canada's National Capital Region in 1950 by Jacques Gréber, commissioned by the Federal District Commission of Ottawa, Ontario.
The report was ordered by William Lyon Mackenzie King at the end of the Second World War and was used as the model for the development of the National Capital Region for more than 50 years. Parts of Gréber’s Plan were made into reality, and have since contributed to some of Ottawa’s most iconic areas: the landscaping and plaza surrounding the National War Memorial, the design of Major's Hill Park and Confederation Park, and the reorganization of traffic in the city center.
In February 2019, Ottawa mayor Jim Watson began the process to develop a modern version of the Gréber Plan.

History.
During World War II, most of the downtown Ottawa's green spaces was filled with "temporary" wooden office buildings hastily constructed to house the Capital’s burgeoning civil service. The city’s natural beauty was also threatened with unplanned urban sprawl, while its waterways were fouled by the detritus of the area’s extensive wood-products industry and the untreated sewage of its growing population. At the time, the Government of Canada was entertaining the idea of creating a federal district like Washington, D.C.
In 1936, Prime Minister William Lyon Mackenzie King invited Jacques Gréber, a French town planner, to act as an advisor for planning in Ottawa. A couple of years later, in 1938, Gréber was commissioned by Mackenzie King and the Federal District Commission to develop a vision and urban plan for the National Capital Region. However, war broke out before much could be achieved beyond the construction of the National War Memorial.
Following the War, the report was again ordered by Mackenzie King in 1946. As Gréber never actually came to Ottawa at the time, Public Works Canada was tasked with photographing almost all of the intersections in downtown Ottawa in order to provide Gréber with a sense of the atmosphere and feel of Ottawa.
Gréber published his 300-page "General Report on the Plan for the National Capital" on 18 November 1949, recommending large-scale networks that would alter the face of the national capital. Mackenzie King, who had retired as prime minister the previous year, wrote the foreword to the report. (MacKenzie King passed away two years before the final report was submitted, however.) In 1958, Parliament passed the "National Capital Act", establishing the National Capital Region and a new National Capital Commission (NCC) to bring Gréber's plan into reality. The Gréber Report would serve as the NCC's planning guide into the 1970s.
In February 2019, Ottawa mayor Jim Watson began the process to develop a modern version of the Gréber Plan, a 25-year plan for the city, anticipating breaching a population of 1 million residents, and foreseeing a part of a megaregion to also encompass Toronto and Montreal.
