Leave after applying for Citizenship

[phantom85]

Hi,

I know this question has been asked before but answers were indefinite and i would like to double check the recommendations from your experiences and knowledge.

1. Is it allowed to leave canada after applying for citizenship - complete 1095 days requirement met- ?
2. When is the time to leave canada after applying for citizenship (do we need to wait after we receive a confirmation on citizienship application or when exactly)?
3. would that complicate and delay the processing of citizenship application?

Thanks,
BK
