PR card information change

Hi Everyone,

I received my COPR approval on Nov 21 and did my soft landing on Dec. 21. I stayed few days in Canada and returned back to united states (i was a US green card holder ) . My CoPR also mentioned my Original Country of Citizenship (Sri Lanka)

Recently i became a US. citizen . In this case , do i have to inform them (IRCC) regarding that my citizenship got changed ?

How do I get my Citizenship details changed in my Canada PR card ?

Appreciate any response.

thank you
