The Arboretum
Arboretum could be in danger. There's a chunk of that that is part of the arboretum, a lot of rare old trees. It is a national treasure. Will there be some kind of reassurance given that when they go in there, are they just going to clear-cut or will there be some kind of protection for these beautiful old trees? Old exotic trees, hedges by the tennis courts. (Google: "As we heard it report-pdf-Kitchissippi Ward" page 10/10.)

The Queen Juliana Park is outlined in blue. At least 500 trees will be removed if the Civic builds a hospital on the Sir John Carling site, see the letter to the National Capital Commission from former Ottawa Mayors Jacquelin Holzman and Jim Durrell. "Hundreds of trees will need to be be cut down. Yes, we counted but we stopped at 500!"

This document is from a book at the Ottawa Public Library downtown.Environment Canada was located in Building #8 in 1972.

This map is not accurate because the Dominion Observatory property is in "The Danja Zone"; the hospital does not want irregularly shaped parcels of land and Councillor Riley Brockington is" hoping" that the Observatory and other heritage buildings will be spared. No, they will not be spared, councillor. Trees in the Arboretum; the greenhouses, William Saunders Building, K.W. Neatby Building and CFIA Lab are also endangered.
