A PCC older than the commonly cited 6-month window doesn't automatically become invalid — it depends on your travel history to that country since the certificate was issued.
What group members advised:- Pair an older PCC with a letter of explanation. Members said this combination should work in most cases.
- The real trigger is whether you've revisited the issuing country for 6+ months since the PCC was issued — per IRCC guidance, if you visited but stayed under 6 months, the original PCC generally remains valid; a fresh PCC is typically needed if you've spent 6 months or more back in that country since.
The practical takeaway: don't assume an older PCC is automatically rejected — check how long you've spent back in the issuing country since it was issued, and if it's under 6 months, submit it with a short letter of explanation rather than requesting a brand-new certificate.
