Ages on Canadian Census

Ages on Canadian Census Reports | Luxegen Genealogy and Family History:

"Jean Lawson, a Genealogist on the Quebec Eastern Township Rootsweb forum brought us the following very helpful list of the ‘official enumeration dates’ for each Canadian census. It is possible these dates were ignored in some cases or ages incorrectly calculated but for the most part these would be the dates that were used to calculate ages on the Canadian Census Reports.

‘The dates traditionally given below for each census is the “official
enumeration date”. The actual enumeration could have taken weeks or months
to complete . . . . ."


1851 to 1881 Census
The age given is the age on their last birthday.

1891 Census
The age given is the age on their last birthday.

1901 Census
The 1901 Census was taken March 31, 1901.

The age given is the age on their last birthday.

This is the only census that contains actual dates of birth,
which may or may not be correct. It contains the year of immigration.
