Document Requirements
What records you need for each person in your line of descent — from you back to your Canadian ancestor.
For Each Person in Your Chain
You must document every person in the line from you to your Gen 0 Canadian ancestor. For each person, provide one or more of the following in priority order:
| Priority | Document Type | Notes |
|---|---|---|
| 1 | Birth certificate | Best option. Government-issued, certified. |
| 2 | Baptism / birth record | Widely accepted. Church records often predate civil registration. |
| 3 | Marriage record | May be acceptable if it lists the parents' birthplaces. |
| 4 | Death record | May be acceptable if it accurately lists parents' information. |
| 5 | Other records | Census, WWII draft registration, probate records, military files, etc. |
What if Records Don't Exist?
Missing records are common — especially for older generations and Quebec ancestry. IRCC understands that not every record survived.
Get a "negative search result" letter
Contact the relevant vital statistics office or archive and request a letter confirming that no record exists for the person in question. Include this in your application.
Confirm you don't qualify to order the document
Some records aren't publicly accessible yet. Get confirmation that you do not qualify to obtain the record (e.g., too recent, access restricted to immediate family only).
Write a cover letter
Explain why records are missing in a brief cover letter. You don't need to share personal family details — just explain the archival gap. IRCC reviewers are familiar with regional record-keeping histories.
Name Discrepancies
Name discrepancies are common and generally fine for IRCC — especially for:
- Nicknames vs. legal names (e.g., "Bill" vs. "William")
- Anglicized names (e.g., "Jean" → "John", "Marie" → "Mary")
- Spelling variants (e.g., "McDonald" vs. "MacDonald")
For formal legal name changes (marriage, court order), document them with the relevant certificate. For informal variations, you can explain them in your cover letter. Census records showing both name versions are particularly useful.
Age Discrepancies
Small age discrepancies between documents are expected — people historically lost track of or misreported their ages. IRCC reviewers understand this. Matching the day and month is more important than matching the year. Include all records you have and note the discrepancy in your cover letter if it's significant.
Group Applications
Family members can apply together — one package, one mailing. Each applicant needs their own CIT0001 and their own fee payment. Shared documents (e.g., a common ancestor's birth certificate) need only one copy. Organize the package with each applicant's forms together, labeled clearly.
