History
Construction of the Couchiching lockstation
Constructed: 1914-1920

The last lock to be built, this section of the Severn Division commenced in August 1914, but work stopped in 1917 due to wartime shortages. Construction re-commenced in 1919 and the lock was officially opened in July 1920. In addition to the lock, the contractors also built a new railway bridge for the Candian National Railway that was diverted because of the canal.
