LOL, same case with me. I sent a change address request via webform weeks ago (address update form has been failing), but never got confirmation. I decided to wait it out earlier with the client support centre agent (30 mins), they confirmed my address in their record was the new one already.Hello, my gf and I received our pr cards today in the mail. We applied separate for pr and landed on Jan 2nd in Toronto. When my gf was doing landing she was able to change her mailing address with the officer was told that she would receive pr card in that address. The officer that did my landing process did not want to change my address and gave me an Address notification form ( the one that you have to fax). I tried the two online tools to change my address but my application was never recognized.
I sent an IRCC webform on Jan 3rd to notify my change of address, but never got a confirmation.
Today I was able to get a hold of cic and the officer told me that my address was changed on Jan 3rd and my pr card was sent last friday. Today we got our pr cards too!
So IRCC webform does work.
Also, be aware that on the letter, it does state "Do not Forward", so get your address changed if you move and do not rely on mail forwading if you are planning to do so.
Thanks to everyone in this forum. Your help and experiences are greatly appreaciated.
