For context 200m would be somewhat taller than Marriott, 252m would be barely taller than Stantec and 300m would be taller than anything Toronto has currently, save the CN Tower. I expect it would be in the range between Marriott and Stantec. The term "ultra tall" gets tossed around fairly loosely but it is a standard that includes buildings over 300m (as 'O' has noted).
