I’m sure this has already been talked about, but I’m curious as to why they left this – but torn down the rest of the building?
I heard somewhere it’s because there’s a rare bird living in there ??
& Anyone know what will they will be building in the lot?

This is the old lot of Central collegiate Highschool on Dunlop st.
