This is Conservatory we're talking about - the slowest developer in Toronto I'm aware of. I am surprised this building is going up at the rate that it is.
Mattamy managed to construct not one but two Vita buildings next door in the time it took Conservatory to dig the hole in the ground and then proceed to spend a couple of years on constructing the underground floors... I dread the thought that they still own one more parcel of land here in Humber Bay Shores.
So to answer your question about the April move-in: I wouldn't bet on it.
