Wandering along Toronto's waterfront to try the worlds shortest ferry ride, I trip over this building, fenced off and derelict.
According to Wikipedia, they were built in 1928 and a very early example of non-flammable concrete silos rather than wooden ones. They are 120 feet high.
In the UK, I'm sure someone would have snapped these up years ago for conversion into waterfront apartments. The Canadians seem slower at this, but then they are thinking museum, which would be much nicer. Mind you, with all the rusty mechanical bits, I think they have a charm of their own as they stand.
