Rideau Canal - History - Construction Deaths

Construction Deaths

As many as one thousand of the workers died from malaria, other diseases and accidents. 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 magnitude; in 1827 there were 7 accidental deaths recorded. Inquests were held for each accidental death. The men, women and children that 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.

There are three canal era cemeteries that 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 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.
