I phoned IRCC in Monday and they confirmed me about this, although replied very uncomfortably as they donot like this at all. The implied status does not lost for PGWP applier crossing the border. You can confirm with IRCC directly and get the information from them.No , actually officer at the canadian border told me do not work now as you crossed the border so your implied status does not exist now. I am going there again on Thursday and hope for better results this time. Actually I Went to Emerson border which is known as very strict service.
I was planning to Emerson two weeks later. Glad to hear you are also from Manitoba.
Please update your experience after this Friday if this is convenient. I really appreciate it.
