St. Lawrence Seaway
The St. Lawrence Seaway opened in April of 1959 with two Canadian Coast Guard vessels
leading a ship through the St. Lambert Lock at the Montreal entry.
The official inauguration of the Seaway was held on June 26, 1959. This date is probably the most important in the history of St. Lambert. Sa Majesté la reine, en compagnie du général Eisenhower, président des États-Unis, à l'inauguration de la Voie maritime du Saint-Laurent. I can think of no other occasion when the Prime Minister of Canada, The President of the United States of America, and Her Majesty the Queen, all visited the town at the same time.
