The St. Lawrence Seaway is a system of locks, canals and channels. Construction of the seaway began in 1954 and it opened on April 25th, 1959. It consists of a 189 mile (306 kilometer) stretch of the seaway between Montreal and Lake Ontario. The Seaway is considered to be an engineering feat with 7 locks in the Montreal – Lake Ontario section which lift vessels to 246 feet (75 meters) above sea level. The 28 mile (44 kilometer) Welland Canal is the fourth version of a link between Lake Ontario and Lake Erie. Today there are 8 Canadian locks which lift ships 326 feet (100 meters) over the Niagara Escarpment. The St. Lawrence Seaway Authority is a Canadian Government Crown Corporation which is financially self-sufficient. It depends on the tolls charged to the users of the Seaway for its revenue and operating expenses.

The Welland Canal Company was formed in 1824 by William Hamilton Merritt. Construction of the first Welland Canal began in 1829 and was completed in 1834. The canal ran south from Port Dalhousie along Twelve Mile Creek to St. Catharines. An extension was built in 1833 to Gravelly Bay, now Port Colborne. As ships became larger and the wooden locks deteriorated, the need for a new canal became apparent. In 1839, the government purchased the Welland Canal Company’s assets and began making plans for the construction of a second canal. Construction began in 1841 and was completed by 1845. In 1887, a third Welland Canal was completed, which operated until 1932, when a fourth canal was completed. This canal remains in operation today.
