The modern Welland Canal is actually the fourth version to be built since 1829. Unlike the later government-operated canals, the First Welland Canal was built by a private company.
The outline on the ground represents a typical lock from the First Canal. Compare the outline to Lock 3. How have the locks changed?

Dressed stone was used to build the Second Canal (1845) and Third Canal (1881). The gates of the early canals were manually opened and closed. Large balance beams, or levers, projected out from the top of the gate to help 'balance' the mass of the gate leaf and facilitate its movement by locktenders and ship crew.
Early canals were too narrow to navigate a sailing ship. Teams of horses, mules or oxen - driven by a towboy - would move along a towpath beside the channel, towing vessels with their sails furled. The Third and Fourth Canals were built for steam and diesel ships capable of transiting the Canal under their own power.

Adjacent to the lock outline, the stone blocks define the increased width of the Second Welland Canal. The subsequently enlarged width of the Third Welland Canal (1887)
is approximately 1 m (39 in.) from the fence. Similarly, the length of the locks for the Second and Third Canals are shown to the north by stone blocks measured from the upper gates of the First Canal outline.
Remants of the stone locks from the Second and Third Welland Canals can be found throughout St. Catharines and neighboring communities. A ten-minute drive from Lock 3 will take you to the location of an excavated lock from the First Canal - Lock 24 off Merritt Street. Sections of the Second Canal can be found in Mountain Locks Park on Glendale Avenue.
Caution! climbing on the artifacts can be hazardous
Learn about the earlier Canals on your visit to the St. Catharines Museum, before you set out to explore the Canal remnants.
