Points of Interest

  • Chaffey’s Lock Community Hall – This Historic Building was built on bake sales, dances, and raffles, and with nails, boards and labour donated by the community. At the helm of this tremendous community effort was the Chaffey’s Lock Women’s Institute, which succeeded in its goal of opening the Hall in time for the 100th anniversary of the Rideau Canal in 1932. 
  • Chaffey’s Lockmasters House & Museum (seasonal) 
  • Chaffey’s Lock Memory Wall & Outdoor Chapel - Heritage Plaque - Located at the entrance to Chaffeys Lock cemetery, the memory wall was erected by the Chaffey’s Lock and area Heritage Society to commemorate the founding, building and continuing life of the community. Buried in this cemetery are Samuel Chaffey and his wife, Mary Ann as well as 79 individuals including Rideau Canal labourers, mostly Irish immigrants, who died in the construction of the Rideau Canal. The stones of the masonry wall hold plaques inscribed with the names of families who settled in this area. 
  • Chaffeys Lock is home to Queen's University Biological Research Station (QUBS), an offsite campus dedicated to nature studies and host to North America's largest Herbarium
  • Heritage Plaque: Chaffey’s Mills A provincial plaque erected at Chaffeys Lock commemorates Chaffey’s Mills. Falling water powered Sam Chaffey’s extensive milling complex here on the Cataraqui system in the 1820s and a small settlement known as Chaffey’s Mills flourished briefly. However, construction of the Rideau Canal necessitated the demolition and flooding of Chaffey’s mill sites.
