Your guess is wrong.
1. A 160 acre site, formerly a lumber yard, that has had almost all of its buildings removed. It is currently subject to a private-sector proposal to build a large mixed-use development (primarily office buildings aimed at the booming mining sector). A Toronto/Thunder Bay architecture firm has a vision regarding the red iron ore trestle on the southeastern edge of the property, which won an award last fall. Hopefully this project is successful.
2. Manitoba Pool (Agricore). Abandoned suddenly in 1995. If you go in there, you'll find everything in the spot it was when the employees went home the day they were laid off. The property owes $260,000 in back taxes and is for sale by the city.
3. Canada Malting Elevator. Still in operation.
4A and 4B: The Viterra (formerly Saskatchewan Pool 7) complex. Viterra B (labelled 4B) is the largest single grain elevator in Canada, and the third largest in the world. (Unless China has covertly built a larger one.)
5: A portion of a grain elevator that has been left standing for some reason. There are a couple examples of this here and I am not sure why it is done.
6: United Grain Growers Terminal M, operational but not in use. Currently subject to a proposal to be turned into a demonstration grain elevator museum, which would be functional and educational. The elevator is a backup-backup for Viterra's local operations.
7: This entire pier is subject to two proposals: One from from a community group to turn the UGG elevator into a demonstration elevator and the grounds into a sort of festival ground, and one from the owner of the land around the eleevator, the city's port authority, to turn it into a cargo loading facility. The latter proposal will probably prevail.
8: Agricore S Terminal. Owned by Viterra, and used when Viterra's other three operational elevators are at full capacity. When this one is also at full capacity, the UGG elevator to the north is used as well.
9: Parrish and Heinbecker Elevator, the oldest, smallest, and longest operating locally owned elevator in Thunder Bay.
10: The footprints of two elevators that are long gone.
Of the 7 elevators in that area (not counting the silo stub), when that satellite photo was taken, 5 were operating and 2 weren't. I think currently it is 4 and 3. Only the Manitoba Pool is inoperable. There are another 9 elevators in the city. Two are condemned due to fire/explosions (one explosion overshadowed the bombing of Nagasaki in many newspapers; an arson in another 9 years ago put two teenagers in jail and left the facility unusable), two are abandoned, and the other 5 are in operation. So of 16 elevators, 9 are currently running, 4 cannot be used, and 2 are idled. At the harbour's peak, we had 34 elevators.
