It’s the date your eCoPR is issued. Your eCAS will also state that you entered Canada at ...... on DDMMYYY and became a PR. There’s no confusion about it.My photos are still in review with IRCC. I don't know how long did it take them to accepted.
In COPR what is date of your becoming PR (Is the date your PR has been approved?) I wanted to know because I'm worried of do the calculation of my days towards citizenship. I guess I'm PR since the day my application was approved?
