At Poonamalie Lockstation, west of Smiths Falls, the defensible lockmaster's house stands on the north side of the lock.
The Government of Canada recognized the Poonamalie lockmaster's house as a Federal Heritage Building on April 30, 1992. The building, designed by Royal Engineers, originally had only the ground floor. The addition of the second storey came later with its roof built as an exact replica of the original roof. Now a private residence, it is the only remaining residence among those constructed on the site during the canal's military administration. Information sourced from Canada's Historic Places.
