There is also an official plan in which they lay out important goals for the city such as what our 'traditional main streets' will be and who can build what where. Somewhere in this they have stated that Gloucester should be some imaginary border between tall and short buildings downtown and, in order to build something taller, you have to get a minor variance....or in the case of Tribeca just promise a national portrait gallery that was destined to fail with the conservatives in power.
O-Town you're right, the view protections from Parliament Hill are one thing and they apply specifically to the Central Area, although their "projection" south of the Central Area would be taken into account. Gloucester Street was the boundary of the Central Area adopted in the early 1970's as a way to preserve a residential neighnourhood in Centretown and demarcate where office towers would be approved - kind of a "line in the sand" for the office core of downtown. At the time, the thinking was that without such a line, the office core would reach all the way south to the Queensway and there would be nobody left living downtown.
The Mid-Centretown CDP which is currently underway won't change that boundary but recognize that there is a viable residential community south of Gloucester Street and that there is also a vibrant mixed-use neighbourhood in Centretown that actually has thousands of office jobs (just not in tall towers like further north). That CDP will also address the issue of tall buildings in Centretown (where they'd be OK, under what circumstances, how to make them blend in with an established lower-rise fabric, etc.). Remember too that much of Centretown is a Heritage Conservation District. Knowing that new buildings are OK on what today are parking lots, how do we integrate new (and maybe taller) buildings into a historic district. This will be a refresher of planning policy for Centretown, which right now dates back to the mid-1970's.
