I sent my citizenship application just today morning and just now realized that I printed the 'unit number' incorrectly for one of my previous addresses. Like I entered the unit number as 301 instead of 309 for an address where I lived 3 years back. I had driving license of this address so they have a record if this address. Could you guys please tell me the possible implications of this?
Well, you can request to the courier to hold and return the package, and then re-mail again after correction.
OR, you can wait for months until package is opened by ircc office, setup your file, assign application # etc, send you AoR. Then you can send a Webform with explanation.
Thank you @Mike263 and @k.h.p.
I did try calling Canada Post but they do not entertain such request for stopping a mail deliver. So I guess I will just wait till it get's logged in the system and put in a change request. Thank you for helping.
