Community Update: Final Phase of Work to Begin September

Rideau Canal National Historic Site

Edmonds Weir

September 14, 2018 – The final phase of work at Edmonds Lock 25 on the Rideau Canal National Historic Site will begin in mid-October. This phase will focus on additional repairs to the historic masonry of the weir. Work will include grouting, repointing and dutchman repairs – where portions of stone are replaced – along the weir.

The first phase of work began in fall 2016, with repairs to the lock masonry. The full project is expected to be completed in spring 2019.

This 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. These historic investments will mitigate health and safety risks, halt the loss of nationally significant built heritage and stimulate the economy in communities across the country.

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 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.
