1852 Census of the Province of Canada
The census planned for 1851 was not carried out until 1852, so it is variously referred to as the 1851 Census and the 1852 Census. It is important to note that many parts of the 1851/1852 Census were lost or destroyed and are therefore missing from the indices.
