Many Congratulations Mate,
It seems your PPR mail came from Ottawa because CPCO means Case Processing Center Ottawa! It is very strange because you were confirmed by IRCC, your file is at CIO-Sydney. Please check at the bottom of the mail, there should be an address to send documents. Is it Ottawa? If so then it is certain that the email came from Ottawa,ON not Sydney,NS.
Not getting this, why is this misinformation circulated by call center agent and the MP himself?
Anyway enjoy the moment, all the best for your Canadian life
