Are you in Canada ? If yes, you could explain to your employer that you are waiting for IRCC decision on your PR application and you have applied BOWP so you have implied status to continue to work in Canada.Roughly 5-6 months processing, and you can apply within 4 months of your current work permit expiry at the earliest. I'm exhausted by the process. I have a job offer that will wait for me until the end of the year - I will miss out if I don't get my status sorted out.
