caption_attribution_description: Brewer's Mills is a lockstation on the Rideau Canal, Ontario, Canada.
context_page_description: The Rideau Canal, also known unofficially as the Rideau Waterway, connects Canada's capital city of Ottawa, Ontario, to Lake Ontario and the Saint Lawrence River at Kingston, Ontario. It is 202 kilometres in length. The name Rideau, French for "curtain", is derived from the curtain-like appearance of the Rideau River's twin waterfalls where they join the Ottawa River. The canal system uses sections of two rivers, the Rideau and the Cataraqui, as well as several lakes. The Rideau Canal is operated by Parks Canada.
  The canal was opened in 1832 as a precaution in case of war with the United States. It remains in use today primarily for pleasure boating, with most of its original structures intact. The locks on the system open for navigation in mid-May and close in mid-October. It is the oldest continuously operated canal system in North America, and in 2007 it was registered as a UNESCO World Heritage Site.
context_section_description: As many as one thousand of the workers died during the construction of the canal. Most deaths were from disease, principally complications from malaria (P. vivax), which was endemic in Ontario within the range of the Anopheles mosquito, and other diseases of the day. Accidents were fairly rare for a project of this size; in 1827 there were seven accidental deaths recorded. Inquests were held for each accidental death. The men, women and children who died were buried in local cemeteries, either burial grounds set up near work sites or existing local cemeteries. Funerals were held for the workers and the graves marked with wooden markers (which have since rotted away—leading to a misconception that workers were buried in unmarked graves).
  Some of the dead remain unidentified as they had no known relatives in Upper Canada.  Memorials have been erected along the canal route, most recently the Celtic Cross memorials in Ottawa, Kingston and Chaffeys Lock. The first memorial on the Rideau Canal acknowledging deaths among the labour force was erected in 1993 by the Kingston and District Labour Council and the Ontario Heritage Foundation at Kingston Mills.
  Three canal era cemeteries are open to the public today: Chaffey's Cemetery and Memory Wall at Chaffey's Lock—this cemetery was used from 1825 to the late 19th century; the Royal Sappers and Miners Cemetery (originally called the Military and Civilian Cemetery and then as the Old Presbyterian Cemetery) near Newboro—used from 1828 to the 1940s; and McGuigan Cemetery near Merrickville—used from the early 19th century (c. 1805) to the late 1890s.
