Rideau Canal National Historic Site

Enclosure for the completion of winter work at Edmonds Lock 25
April 27, 2018 – The second phase of construction at Edmonds Lock 25 on the Rideau Canal National Historic Site is now complete.

The contractor has finished stone masonry repairs within the lock chamber. They will be removing the enclosure around the lock and demobilizing from site next week. In May, they will complete site restoration in advance of the 2018 navigation season.

The final phase of work at Edmonds is scheduled to begin this fall. This phase will focus on repairs to the historic masonry of the weir. The entire project is expected to be completed by spring 2019.

The Edmonds Lock 25, Overflow Dam and Weir project is essential for preserving the historic, aesthetic, and functional integrity of Edmonds Lockstation for generations to come. The project is part of Parks Canada’s unprecedented $3 billion dollar investment over 5 years to support infrastructure work to heritage, visitor, waterway and highway assets located within national historic sites, national parks, and national marine conservation areas across Canada.

About Edmonds Lock 25, Dam and Weir

Edmonds Lock, Dam and Weir were constructed in the late 1820s to early 1830s. The lock was created with a 2.64 metre (eight foot, eight inch) lift, built on a clay foundation and wooden floor. A stone arch overflow dam was built with a waste weir installed to reduce the chance of floods. In the early 1840s, a stone lockmaster's house was constructed at the site then replaced with a two-storey house in 1905.
