Hi, I’m kinda in the same situation. I applied for PR under CEC on March and was awarded 50 points for arranged employment and my closed work permit expires on Septermber.
My employer gave me another LMIA so I applied for another cwp while waiting for my PR.
Unfortunately, I got terminated.
I informed IRCC and applied for bridging open work permit right away using the AOR I received when I applied for my PR.
I regret not to apply for bowp right away after I received the AOR from applying my PR because I not know I will get terminated.
For now, I waiting to get my PR or my bwop approval because I cannot work yet.
