June 26, 1959
Queen Elizabeth II and American president Dwight D. Eisenhower dedicated the new St. Lawrence Seaway. The dedication ceremony took place at St. Lambert, Quebec. President Eisenhower described the Seaway as a "magnificient symbol" of what two democratic nations could do "for the common good," reports the New York Times.
The Royal yacht, Britannia, with the British Soveriegn and the US president on board was given special precedence through the locks on the Seaway. The new St. Lawrence Seaway will allow large vessels to travel from the Atlantic Ocean to the Great Lakes. This will be done through a series of canals and locks.
