Hi, I'm experiencing similar issues to everyone above. I mailed my application in on Friday, April 3, only to find out they started accepting online applications the next Monday. According to Canada Post, they received my application on April 8th. Today (April 21st), I received a letter from Service Canada (sent on April 13th) that says:
"We were not able to process your SIN online request as certain essential documentation pertaining to your application was missing." It then lists the documents required, and tells me to reapply online.
I'm super confused because
1. I applied by mail, not online and
2. I definitely gave the all the documents they required (the mail application even has a checklist).
3. Even if the online application were open (which it's not), I can't apply online because the SIN office still has my passport AND my COPR letter.
Like everyone else, I've tried calling numerous times only to get "we are experiencing longer than usual wait times" etc. etc. before it hangs up on me. Has anyone else experienced this? Does anyone have any suggestions? I'm currently without a passport, a COPR, and my PR Card application is completely AWOL (I landed on March 12 and the application status website says it can't find my application).
