Battered by the elements, notably the cold winds and rain that sweep off the Bay of Fundy, and stressed by the weight of the two-storey concrete fire command post added to the top of the tower in the Second World War; Carleton Martello Tower has been plagued by leaks for a number of years. Investigative work in 2015 revealed the tower to be in a state of critical failure. In response to the urgent work required to conserve Carleton Martello Tower, the Government of Canada committed $13 million in 2016 to rehabilitate this national historic site.

The recommended conservation option will preserve the 1812 martello tower by repairing its walls and vault, and by removing the original concrete fire command post. The command post will be replaced with a light-weight replica, which will ensure that the site’s connection to the Second World War will continue to be shared with Canadians.

Investigative work will begin during the 2016 operational season and will be followed by restoration and reconstruction activities that are expected to be completed by 2020. During this period, the 1812 tower will be closed to visitors; however, Carleton Martello Tower National Historic Site will remain open to visitors to enjoy and explore the Visitor Centre, Exhibit Gallery, and grounds.
