I am sorry to know that you had lost your important documents including the passport.
Passport is a crucial document (mainly stamps) to show entries and exits. Did you by any chance have recent photocopies of all pages of your passport, and if yes, did you submit them along with RQ or with the application?
You can search online and this forum for such scenarios happened with other people too( I am talking about lost passport).
At the end it is upon Citizenship Judge's discretion to grant you citizenship or not. It will depened upon how strong your ties are with canada and what supporting documents you have submitted.
Good luck!
thank you so much for your answer thecoolguysam,unforunitlly , i lost my passport , i just have the copies of 3 first pages
