That's what I was thinking too (BOWP), but I thought I could get a 100% refund, anyways I will do it by the last day (August 22nd).I think you can make it before August 24th...
If you don't receive your eCopr around August 20th you still have the option to submit a Bridging Open Work Permit.. (if you want to continue working, of course). The bad news about that permit is you need to pay for it, but they send a letter saying that you can work until a decision is made. (implied status).
Of course (and hopefully) you are going to receive your eCopr before that open work permit, in that case, IRCC refunds you around $100 for that Bridging Open Work Permit you already paid for.
How about my son? He is on a Student Visa, do you know if I need to apply to extend his Visa? Or he can be without status for that period of time.
I know those questions are very specific, any thoughts will be very helpful.
