A claim to citizenship by descent is proved on paper, one generation at a time. The paper exists more often than families expect. It is just rarely in one place.
Start with what the family knows
Before any archive, collect what is already at hand: a full name, including a maiden name; a town or county; a decade; the names of brothers and sisters. A rough date and a place turn a search of millions of records into a search of a few hundred.
Old letters, family bibles, funeral cards and photographs with a studio address all count. They are not proof, but they tell a researcher where to look.
Civil registration
Provinces and territories register births, marriages and deaths. This is the strongest evidence of a birth in Canada, and the first thing to look for.
Two limits apply. Registration began at different times in different provinces, and in the early decades many births went unregistered, especially in rural areas. And recent records are released only to the person named, close relatives or someone they authorize.
Parish registers
Before civil registration, and alongside it for a long time, churches recorded baptisms, marriages and burials. For a birth in the nineteenth century, a baptism entry is often the only record there is.
Quebec is the richest case: its Catholic parish registers run back to the 1600s and served as the civil record. A baptism entry usually names both parents, including the mother's maiden name, which is exactly what a line of descent needs.
Census returns
Census returns list a household: names, ages, birthplaces and how each person was related to the head of the house. They don't prove a birth, but they place a family in a location and confirm who the parents were. Library and Archives Canada holds the historical returns that have been opened to the public.
Border and passenger records
Families that left Canada usually crossed into the United States, and families that arrived came by ship. Passenger lists and border entry records can show when someone entered or left, with whom, and where they said they were born. They help connect a person in Canadian records to the same person in another country's records.
Naturalization and citizenship records
If your ancestor immigrated to Canada and became a citizen, the date they did so decides whether citizenship passed to their children. Historical naturalization records are held by Library and Archives Canada. More recent citizenship records are held by Immigration, Refugees and Citizenship Canada, which can search them on request.
Records from outside Canada
A line of descent doesn't stay in Canada. Each generation born abroad needs a birth record from the country of birth that names the parents, and marriage records where a surname changed. These come from the civil registries of those countries, and may need certified translation.
When the record isn't there
Registers were lost to fire and flood, and some births were simply never recorded. When that happens, researchers look for the next best evidence: a baptism instead of a birth registration, a marriage record naming parents, a census entry, a delayed registration made later in life.
Whether a substitute is accepted is the government's decision, not the researcher's. An honest file states plainly what was found, what wasn't, and what stands in its place.
