When to surrender PR card?

[juicemango]

Hi all,
We are currently PR and planning to apply to be a citizen in the future. My understanding, at one point, we have to surrender our PR card. Anyone can tell me when do we need to surrender the card?

Currently, it takes 15 months to be a citizen, I'm assuming, we should surrender PR card toward the end of the 15 months process?

Thanks all!

You surrender the PR card on the day you get sworn in as a USC.
