Extreme Dilapidation

This is a grey, rectangular 4 floor building at King st and Cowan ave. The first floor is a bit of a half-assed basement so I am unsure whether it counts as having 3 or 4 floors, but you can judge from the photos. Inside the building is in a fairly extreme state of decay. The walls are peeling, the floors are unsafe, it's a junky jungle in there. It presents some quite interesting photo ops, especially on the top floor where there might have been a fire. Unfortunately, I have been unable to find any info on this building online, probably because there is no visible street number. It was probably a residential building, since inside one can find mailboxes and a lot of steel bath tubs. I'd like to imagine it was one of those fabled Parkdale rooming houses from the 80's.
