[QUOTE=wacko;7546453]Assuming CNIB owns the building while the province owns the land: does the grandfathering allow CNIB to expand the footprint of the building or make substantial alterations to it?[QUOTE]
Anything CNIB wants to do would require WCA approval.
The current Conexus "controversy" notwithstanding, WCA has actually been quite consistent in maintaining the spirit & character of the Centre. Developments have tended to be arts/education/culture/govt, and they've typically kept with the aesthetics articulated in the Master Plans. So, I suspect WCA would approve changes/development the CNIB building, so long as they are in keeping with the Master Plan (ie: not a stuccoed monstrosity).
I think this speaks to the value of a living document like the Master Plan - it doesn't get amended on a whim, but it's also not carved in stone... it adapts gradually & thoughtfully over time. Very few examples of significant deviation from the Plan in place at the time of a given development.
I know it seems boring, but give the 2016 Master Plan a read - fascinating to see how closely the Centre aligns with the original Plan, and where it deviates (and why).
If the City could hold as tightly to the principles of the OCP - and review/update it routinely - wow, I think a lot of the complaints we see in this forum would disappear. Thinking especially of patterns of "one-off" deviations for unique opportunities. Look back 50 or 100 years & contemplate how many of the unique "opportunities" City Council has approved over the years stand the test of time.
Not to say WCA is perfect... but I'd bet on their planning & development track record over the CoR's any day.
