Let's try simplifying it even further.
Did you go to the consulate and did they ask you to place your fingers on a scanner?
Cant remember if this happened last 3 years ago.
Edit:
As of now, I assume I have given it before because IRCC website says that it is mandatory to give biometrics to get a visitor visa. If I have been issued a visa, that means I have given my bio metrics before, right?
Will I encounter issues if I say I have given before, but during review, IRCC does not find any biometric details on their side?
