Narrows Lock 35 Masonry Repairs

Rideau Canal National Historic Site

February 16, 2018: Community Update: Repairs are Now Complete 

In spring 2018, Parks Canada completed heritage masonry repair work at Narrows Lock 35 located on the Rideau Canal National Historic Site. Work included stone replacement, grouting, and repointing to ensure the continued structural integrity and functionality of the lock.

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 Narrows Lock 35

In 1830, Colonel By developed a plan to build a dam and lock across the Upper Narrows forming a new lake – Upper Rideau Lake. The lock was built on a solid rock foundation with gate sluices on both the upper and lower gates. The gates were created with oak sills bolted to rock. A dam was built on either side of the lock, and a waste weir included on the south side of the lock. In the early 1830s a blockhouse was built at the site.
