You do not have to contact IRCC. If IRCC needs you to provide another set of fingerprints, you will be informed.

IBIDS accepts poor quality fingerprints and provides real-time feedback to advise officers when a poor quality fingerprint has been taken.
When CIBIDS advises officers of a poor quality fingerprint, the officer should attempt to take the fingerprint again.
However, the officer can also choose to accept the poor quality fingerprint. The officer must select the appropriate reason for why a poor quality fingerprint was accepted. Officers have the option of including additional notes and should define and record alternative reasons for the acceptance, where appropriate.
The information is displayed in the Global Case Management System (GCMS) and is visible to the Immigration, Refugees and Citizenship Canada (IRCC) officer assessing the application.

Temporary conditions and poor quality biometrics
In cases where an applicant’s physical condition prevents the officer from obtaining good quality fingerprints or a good quality photograph, either of the following scenarios can take place:
- the officer may defer the biometric enrolment until the applicant’s condition improves, if there is a reasonable expectation of improvement in a short time
- the applicant may choose to defer the biometric enrolment until the condition improves
Officers should check the window of time an applicant has to enrol. If the enrolment period specified in the Biometric Instruction Letter will be exceeded, the applicant must notify IRCC.
