A Canadian census must be read with its year and administrative geography. LAC’s search covers censuses from 1825 to 1931; early series and territories differ in content and survival.

The method, step by step
- For pre-Confederation censuses, establish whether the series names individuals or only household heads. LAC’s guide distinguishes formats and exceptions. A child missing from a heads-only list cannot therefore be assumed absent from the household.
- Identify province or territory, district and sub-district for the census year. A small locality may have been enumerated within its surrounding township or civil parish. Keep the historical name and area number instead of relying only on the modern municipality.
- If name searching fails, try other known household members, then browse the area. Read column headings before comparing years: questions change. Record people, ages and occupations as written, without smoothing differences.
- For the citation, keep year, province, district, sub-district, page, household or dwelling number where present and reproduction reference. Compare the household with civil or church records; adjacent lines alone do not establish kinship.

Frequently asked questions
Why might an early Canadian census omit children’s names?
Some early series name only household heads, not every person. Check the year and area’s format before concluding a child was absent.
