Prior to June 2026, Immigration, Refugees and Citizenship Canada (IRCC) didn’t describe acceptable documentation for Canadian ancestors who were born in the 1800s or earlier. Their web page “Apply for a Canadian citizenship certificate: How to apply” was silent on this issue.
An archived version of the page is available here:
As a result, genealogists could only find and supply documents that provided evidence of birth based on genealogical best practice. See, for example, When Your Ancestor Has No Birth Certificate: Genealogical Proof and Canadian Citizenship.
Around June 18, 2026, however, IRCC added detailed information that’s especially relevant for Canadian ancestors born in the 1800s.
The most useful change is this: there’s no stated requirement to search for a birth registration or baptism record before using census records to prove an ancestor was born in Canada.
The revised page is available here, but I’ve included relevant screenshots below, because it’s clear this page is liable to change.
A newly added list called “What we accept” says, “[Y]ou must provide . . . 1 of the following documents,” and then, of all the documents listed, only one would be relevant for a Canadian-born ancestor, namely, a “provincial or territorial birth certificate.” (See screenshot, below.)
What if there’s no birth certificate?
If you’re applying for a certificate under the provisions enacted by Bill C-3, your Canadian ancestor was probably born before the earliest birth year for which their province’s vital statistics agency issues birth certificates. In that case, a birth certificate is not available.
That’s because, after a legislated period of time, the birth registrations that each province’s vital statistics agency uses to create birth certificates are transferred to the provincial archives. For those years, the vital statistics agency can no longer issue a birth certificate.
The following chart shows the earliest birth years for which each province can issue a birth certificate:
| Province | Earliest year available (birth registration retention period) |
|---|---|
| British Columbia | 1906 (120 years) |
| Alberta | 1906 (120 years) |
| Saskatchewan | 1926 (100 years) |
| Manitoba | 1926 (100 years) |
| Ontario | 1922 (104 years) |
| Quebec | 1994 (birth certificates can be issued retroactively by the Directeur de l’état civil) |
| New Brunswick | 1931 (95 years) |
| Nova Scotia | 1926 (100 years) |
| Prince Edward Island | 1906 (120 years) |
| Newfoundland and Labrador | 1926 (100 years) |
If a birth certificate is not available, what document(s) will prove my ancestor was born in Canada?
IRCC’s new instructions are clear. (Well, sort of clear.) The documents you provide should probably be certified copies. And a new section called “If you’re missing any birth certificates” provides a helpful list of acceptable documents that includes records of birth, baptismal records and census records.
Certified copies are required. (Sort of.)
The new requirements don’t explicitly state you must provide certified copies. However, the documents must be issued by the “original authority” that keeps the originals (e.g., the archives), and must “clearly show who issued the document.”
So while IRCC doesn’t use the term “certified copy,” they’ve exactly described a certified copy of a birth registration, baptism or census record: the original is kept by an archives and the copy includes the name of the official who issues it.
Again, given the likelihood of web-page change, I will use a screenshot to document this instruction:
Birth registrations, baptism and census records: all the same to IRCC?
The new instructions include a section called “If you’re missing any birth certificates.” This will absolutely be the case for an ancestor born in Canada before the earliest year in the table above for their province.
In this case, IRCC will accept any of the following, as long as it was “issued by the original authority that created or keeps the record” and clearly shows who issued it:
- a record from a physician or midwife who witnessed the birth
- (Much like IRCC’s description of what are essentially certified copies (see above), this is probably “IRCC-speak” for a birth registration)
- baptismal certificate or record
- census records
Again, because these instructions may change again, here is a screenshot:
Do I have to prove I tried to get a birth registration and/or baptism before I can use census records as proof?
No. According to IRCC’s new instructions, there is no requirement to prove you tried to get a birth registration or baptism record before using census records. (You do still have to show you tried to get a provincial or territorial birth certificate, as explained below.)
The new requirements are presented in three sections:
“Documents proving Canadian citizenship of your parent, grandparent and parental ancestor”
This is the section that states the requirement for documents that are issued or kept by an “original authority” and clearly show who issued them. Here is a screenshot:
“What we accept”
This is the section that indicates you must provide a provincial or territorial birth certificate to prove the citizenship of a Canadian-born ancestor. (See the first screenshot in this post.)
“If you can’t provide official documents issued by the original authority”
In this section, IRCC’s use of the term “official documents issued by the original authority” may be confusing — until you look at the list of documents in the previous section, which includes:
- birth certificates
- citizenship and naturalization certificates
- Certificates of Registration of Birth Abroad
- Certificates of Retention of Canadian Citizenship
- British naturalization certificates issued in Canada or Newfoundland and Labrador
These are all “official documents” that were “issued” to individuals by government authorities.
On the other hand, the documents listed in the sub-section called “If you’re missing any birth certificates” were either never issued to anyone or never counted as “official documents.”
Therefore, these instructions apply when you can’t provide — specifically — a provincial or territorial birth certificate for an ancestor born in Canada. As we’ve seen, a provincial or territorial birth certificate is the only “official document issued by the original authority” in the list provided (see “What we accept”) that applies to someone born in Canada.
So if you can’t provide a provincial or territorial birth certificate — which is the case for everyone born in Canada before the earliest year their province issues birth certificates — you can move on to other types of documents. (See the third screenshot in this post.)
With these new instructions, once you work through the language, IRCC made their documentation requirements for anyone born in Canada very clear. Regardless of when the birth occurred, IRCC wants to see a provincial or territorial birth certificate.
This preference for a Canadian birth certificate is probably why IRCC doesn’t rank the alternatives they’ll accept “If you’re missing any birth certificates.” If you can’t provide a birth certificate — i.e., the only “official document issued by the original authority” they name that applies to a Canadian-born individual — an archival birth registration is no better for their decision making than a baptism record, and neither is better than census records. IRCC’s unranked list of these alternatives, and the lack of any other instructions for their use, make it reasonable to infer they are of equal evidentiary weight.
Census records: the low-hanging fruit of 19th-century citizenship proof
Canadian census records are available online for each decade from 1851 to 1931. Copies printed from Library and Archives Canada’s “Census search” database can be used to support a citizenship certificate application. There’s no need to order certified copies. This is made clear by a notice that appears at the bottom of each results page:
According to IRCC’s new instructions, to prove a Canadian-born ancestor’s citizenship using census records you must do two things:
- Explain in writing why you can’t provide a birth certificate, which would be the “official document issued by the original authority” that proves their citizenship. (Their birth predates the earliest birth certificates issued by their province’s vital statistics agency.)
- Show proof that you tried to get a birth certificate from the relevant vital statistics agency (e.g., an email exchange with the province’s vital statistics agency requesting a birth certificate for someone born in [insert year here, e.g., 1868], and their reply).
Putting it together
In other words, if census records show your ancestor was born in Canada, IRCC’s new instructions let you submit them without first searching for a birth registration or baptism. You will still need to explain why no birth certificate is available, and show you tried to get one.
A final lesson from IRCC’s June 2026 update: screenshot the instructions as they appear on the day you apply, and consider including them with your application. As of this writing, citizenship certificate applications take about three years to process. The page you relied on may not be the page your application is judged against, so keep proof of what it said.
