I got mine thru ATIP-CBSA, free. No permanent tracker number were introduced but received it after 30 days. You’re still on the SLA if you said it’s in 3 weeks time.Yes, if you choose Privacy Act. It is free, but you will never get it.
I had the same thing happen for me, just got the initial mail with temporary reference number. It stated that once the request is registered actual number will be generated, which never happened even after 3 weeks.
