Not a new office conversion, but one done pre COVID.
The old Imperial Oil office building in Toronto was converted to condo apartments.
A guy I know used to work there.
His former boss has bought one of the units.
It is right where his office was. The living room was where his desk once sat.
As to the current situation, the one feeling it the most IMO are the former shops in the PATH.
Lots of entrepreneurs used to seasonally lease there and now tons of these sorts of shops are shuttered.
