Toledo uses the old AMO “river book” for connecting waters of the Lakes. For the Welland Canal, almost all pertinent info cam be extracted from the Canadian chart of the Welland and the Canadian Sailing directions. Lake pilotage is LCA courses amd distances right of the general lake charts while local knowledge is from the Coast Pilot.
That being said, everybody has the own wrinkles once you start working on your license. The REC uses the River Book because they can grade your sketches and narrative from a reference; not because what you put on the exam is how you will actually run the rivers.
