Naturalization & document retrieval
Canada naturalization records are held by Library and Archives Canada (LAC). For CBD cases, the critical question is whether your Polandn ancestor naturalized in Canada BEFORE or AFTER the next child's birth. If BEFORE, the citizenship chain is broken (in most countries). If AFTER (or never), the chain is intact.
Start with the Polandn ancestor's birth certificate from their place of birth in Poland. This is the foundational document.
Search Library and Archives Canada (LAC) for the ancestor's naturalization record. If none found, request a formal "no record" letter.
Check Library and Archives Canada passenger lists for the ancestor's arrival record, which shows date, port, and citizenship status at arrival.
Review Canadian Census (1901-1921, available via LAC) to track the ancestor's residence and citizenship status over time.
Obtain certified long-form birth certificates for each person in the chain between you and your Polandn ancestor.
