I only wrote the name of the city where the office is located. In your case, New Delhi.
If you are really uncertain of how to edit the answer just wait a few more hours so everyone in Canada begins their day and then you should get some answers from more experienced members.
However:
New Delhi is a Visa Office and not a CPC. And the question asks you for a visa office. So should you want to be complete and precise, you must write "Immigration Office" or "Visa Office" New Delhi.
CPCs:
- Mississauga is for outland sponsorship approval [stage one] and PR application completeness checks only
- Vegreville is for inland sponsorship applications
and
- CPP Ottawa is for pre-screened [by CPC-M] applications for US sponsored persons only - in regards to PR applications, anyway.
The question you mentioned is being asked because some people [principal applicants] have resided in more than one country throughout their life and those applicants are able to chose their Visa Office [based on where it takes less time to process stage 2, in most cases - lucky them!].
