you need to wait for tracking number your application has been approved now wait for return tracker
 
How can you find tracking number ?
Actually you should send your passport with an unused envelope which CIC will use to send your passport back, so you are supposed to know the tracking number yourself. Did you take any picture of the used envelope?
 
Yes i took the photo of the envelope which i sent to CIC but i did not took photo of unused envelope. Now what should i do please suggest me .
