To use the STCA family exception, a refugee claimant arriving from the United States must prove, at the port of entry, often in a single day-long examination, that they are related to a qualifying family member in Canada. A statement that “this is my sister” is not enough. CBSA expects original identity and birth documents that show the link, and in difficult cases a DNA test from an accredited laboratory with its chain-of-custody report. If CBSA does not accept the relationship, the claimant is returned to the United States.
This article draws on the STCA panel at the CILA 2026 conference (5 October 2026), including slides by Heather Neufeld, checked against the Immigration and Refugee Protection Regulations (IRPR) and current IRCC pages on 5 November 2026.
Key Takeaways
- The burden is on the claimant. IRPR s.159.5 says the exception applies if the claimant “establishes” that a qualifying family member is in Canada.
- You must prove two things: the family relationship, and the anchor relative’s status and physical presence in Canada.
- Original birth certificates showing common parents and consistent spellings are the core evidence. Missing originals and name variations put the claim at risk.
- DNA testing is not a legal requirement, but counsel at the conference reported using it in higher-risk files, with the lab’s chain-of-custody report sent ahead.
- A wrong decision is hard to fix. Reconsideration is discretionary, and the claimant may already be in U.S. detention.
What does the STCA family exception require you to prove?
Under the STCA family exception, the claimant must establish that a family member defined in IRPR s.159.1 is in Canada and holds a qualifying status under s.159.5, such as citizen, permanent resident, protected person, or an adult refugee claimant whose claim is still pending. Two facts need proof: the relationship itself, and the anchor’s status and presence in Canada.
Which relatives qualify is covered in our hub article on the Safe Third Country Agreement and the 14-day rule. This article is about the evidence.
Two points from the panel are worth knowing early. First, the slides note that half-relatives count but step-relatives do not, so the documents must show a shared biological or legal parent, not just a shared household. Second, a spouse or child cannot rely on the principal claimant as their anchor if the principal’s own claim cannot go to the Immigration and Refugee Board, for example because they first claimed in the U.S. Each family member then needs an independent anchor.
Which documents prove a family relationship at the border?
The strongest proof is original civil documents that link the claimant and the anchor through a shared parent, with names and dates that match across every document. Neufeld’s slides list original birth certificates first, then supporting evidence such as photos together, communications, family registers, baptism certificates, and the family details each person declared in earlier Canadian immigration applications.
A practical checklist, drawn from the conference slides:
- Claimant identity: all original identity documents, with translations. If an original is missing, be ready to explain why and where it is.
- Relationship: original birth certificates for both people. For siblings, the certificates must show the same parents with the same spellings.
- Supporting proof: photos together over time, messages and call history, family books or household registers, religious records.
- Earlier Canadian applications: if the anchor relative listed the claimant on a past IRCC form, that declaration helps. If they did not, expect a question about it.
- The anchor’s status: a PR card, passport, citizenship certificate, or proof of a pending refugee claim.
- The anchor’s presence: proof the anchor is physically in Canada now, such as recent proof of address or employment.
- U.S. status: proof of any pending U.S. applications.
The panel’s advice: check every document for small inconsistencies before the client travels.
What if the birth certificate is missing, late-issued or spelled differently?
These files are most at risk. The slides report clients without original birth certificates being turned back. A recently issued certificate, or one that spells a parent’s name differently from the anchor’s, can raise fabrication concerns even when the relationship is real. Address the problem in writing before the interview.
Practical steps:
- Explain country-specific naming conventions in writing, for example where surnames are not shared between siblings or where transliteration varies.
- If a certificate was issued recently, explain why (the original was lost, or the country only issues certificates on request) and bring any older records that mention the birth.
- Gather sworn declarations from the anchor relative and others who know the family. The slides list affidavits and notarized statements as alternative evidence.
Do you need a DNA test for the STCA family exception?
No. Nothing in IRPR s.159.5 requires a DNA test, and IRCC’s own guidance treats DNA as voluntary and a last resort. But the panel said documentary scrutiny at the border is now so high that, where documents are weak or come from a country with known authenticity concerns, counsel have arranged DNA testing before the claimant arrives.
If you test, meet IRCC’s standards, because an officer is likely to measure the result against them:
- Accredited lab only. IRCC accepts DNA results only from laboratories accredited by the Standards Council of Canada (SCC). SCC publishes the current list.
- Accuracy. IRCC requires results with an accuracy of 99.8% or higher.
- Who gives samples. IRCC’s guidance asks for the child and both parents in a parent-child test, and the siblings plus, where possible, the parents in a sibling test.
- Cost. Under IRCC’s guidance, the client pays all costs, including sample collection, courier and the lab report, whatever the result.
One caveat. IRCC’s procedure is written for tests IRCC requests by letter. There is no published CBSA procedure for a test you arrange before a border claim, so discuss this use with the lab before booking and keep every document it issues.
What is a DNA chain-of-custody report and why does it matter?
A chain-of-custody record shows who collected each DNA sample, where, how it was identified and packaged, and how it reached the lab, so that an officer can trust the samples were not swapped or tampered with. IRCC’s guidance requires it to name the employee who collected and packaged the sample and the legal name of the collection facility.
The panel said many practitioners had not dealt with this document until it became necessary. The practice described was to obtain both the DNA report and the chain-of-custody report from the accredited lab and send them to the port of entry in advance of the claim, together with written submissions.
How should the anchor relative prepare?
The anchor relative should expect to be contacted by CBSA at any time on the day of the claim, and ideally should be at or near the port of entry with original documents. The interview compares answers: names and dates of birth of parents and siblings, where each person lives and works, and how and when each document was obtained.
The panel said CBSA sometimes questions the anchor in detail in a way that fills gaps in the documents, but this depends on the port and the officer. Prepare as if the paper record must stand on its own.
Other preparation points from the slides:
- The Peace Bridge crossing between Buffalo and Fort Erie has a refugee processing unit and takes appointments, and can send forms in advance. Weigh the strength of the exception against the risk of return before choosing a port.
- Have a signed Use of Representative form ready. The claimant has no right to counsel at the eligibility interview, so written submissions on how the exception is met, and how each document shows the relationship, carry more weight.
What happens if CBSA does not accept the relationship?
The claimant is found ineligible and handed back to U.S. Customs and Border Protection, where the panel reported that detention is now likely. CBSA may reconsider on new evidence, but this is discretionary and has no formal process, and the request must explain why the evidence was not available at the first interview.
In Hussein, 2018 FC 44, cited in the slides, the Federal Court described reconsideration as a two-step process: whether to reopen at all, then a fresh decision. If reconsideration is refused, leave for judicial review in the Federal Court may be possible. The slides also suggest asking, in the original submissions, for alternative relief such as a temporary resident permit where there is evidence of serious risk on return to the U.S. The Supreme Court in 2023 SCC 17 treated these safety valves as part of what makes the STCA scheme Charter-compliant. None of these routes is quick.

Frequently Asked Questions
Is a DNA test required for the Safe Third Country Agreement family exception?
No. It is not a legal requirement. It can be useful where birth documents are missing, recently issued or inconsistent, but it must come from an SCC-accredited lab and should be accompanied by the chain-of-custody report.
Can I use a photocopy of my birth certificate at the border?
Bring originals wherever possible. If you do not have one, be ready to explain why and where it is.
Does the anchor relative have to come to the port of entry?
It is not a written rule, but the panel advised that the anchor be reachable all day and ideally present with original documents, because CBSA may want to interview them.
Can I ask CBSA to reconsider if I am wrongly turned back?
You can ask, with new evidence and an explanation of why it was not available earlier. Reconsideration is discretionary, so it should not be treated as a second chance.
