The Toronto Brigantine vessels go through the Welland Canal at least twice each summer! This summer we go through during course 5 and course 8, not sure which one is the one where we go “down”.
Here is a picture of the Pathfinder in the Welland Canal (between Lake Erie and Lake Ontario)
Here is a picture from 1998 of the Playfair going up the Welland Canal between Lock 2 and 3 in St Catherines. The same for the Pathfinder on the Welland Canal. Does that mean that they are going toward or away from Toronto?
Here is another picture of Playfair going through the Welland Canal with a bit of a description of what it is like to go through the locks.
In Aug 2007, the Pathfinder participated in the annual Canal Days festival in Port Colborne with the Empire Sandy, The Challenge, Appledore V and the St. Lawrence II. Here was a write up of the event.
