For several years I worked on ore boats on the Great Lakes.
Yes they are called boats not ships even though some are 1000 feet in length. The most beautiful trip was to an iron ore dock in Georgia Bay. There was deep water but trees overhung the water and we picked leaves from them as we sailed by.
I'm just trying to think where you might be talking about. Are you referring to a dock in the Sault? I can't imagine a dock in the part of the bay enclosed by Tobermory-Collingwood-French River which is what most people think of as 'Georgian Bay'. I don't think there are any steel plants there and any ore going to Hamilton from the Iron Range would stay on the ship until it goes south on Huron and across Lake Erie through the Welland Canal to Lake Ontario....
