Another update for the spreadsheet: my E-CAS status changed to "decision made" on April 15. I'm from a visa exempt country.
To everyone still waiting, hang in there! I heard nothing from CIC for a year, and requested and actioned things on my GCMS notes several times in the last few months. Then they suddenly started and processed my application within 2 weeks.
Anyone know how long the current wait time is between a decision and receiving CoPR in the mail? Also, any tips on the next steps since I am already living in Canada - do I need to re-enter the country?
