I lived in Canada 30 years ago with my parents, I didn't realize I had Permanent Residency - I have visited Canada for a holiday in 2004 and this is my first time applying for an ETA. I got a request letter explaining that I needed to renounce my residency (even though I no longer have one). I completed the documents the same day and uploaded them electronically. However with the weekend and labour day I have not heard back yet on my application. Can someone tell me what the normal turn around time is for this? Unfortunately I am due to fly out this week. Thanks
It's really hard to guess.
Processing times aren't normal right now unfortunately. There's still a backlog due to COVID and most applications are taking longer to process than normal.
Lately, any eTA that is non-standard for some reason is generally taking at least a few weeks to process, if not a few months. You may get lucky and see much faster processing. Unfortunately it's really impossible for any of us to guess and there's no way for you to track process. You'll just have to wait and hope for the best.
Make sure you have a "Plan B" in the event you don't get the eTA in time and have to defer your trip.
Good luck.
