Wow! The current building at 1366 Yonge St that Bazis wants to replace with a 41-storey tower was built only in the 1990s. It's probably no more than 30 years-old. This is the second project, the other being downtown at Jarvis/Earl, where a building from the 90s is going to be demo'd for a new tower. Things happen super fast in this city!
