Here is my timeline for my kid's application:
Application delivered: December 29th
Called on 14th Jan as CC was not charged, came to know that application is in progress
CC charged : January 21st
Birth certificate received: January 25th
Passport collected : January 28th
Note : called passport helpline on Jan 26th n got the tracking number for PP.
The parcel with passport never came to me as there was a typo in address (strange as it was fine for the birth certificate). Collected the from the Canada post on Jan 28th
lLesson learnt: It’s always good to call them whenever you think it’s getting late. If I hadn’t called , I would have never known the status and parcel would be sitting in PO.
