Honestly, if you are counting on Silos to become travel-to-see-landmark on your waterfront, then you need Jesus to save your city's architecture.
Silos belong to farm lands not urban centers and I don't think anyone would wake up in the morning anywhere in the world and scream in excitement to their kids that "We are going to see silos"
Toronto has already missed several opportunities to make our waterfront an envy of the world but admitting several bland gray glass slabs that should have been built in Markham or Milton
We cannot become a joke of the world by embracing old farm land structures containing dangerous gases to litter out waterfront
