When you check your status on CIC's website, what date does it provide where it says "We received your application for permanent residence on xxxxx xx, 2014"? I think they go by that date, at least that is the trend that I was noticing for a while. So it's not actually they date the Purolator delivered the file, but the date that they first looked at the package and found all of the documents to be present. I had originally filed mine on October 5th, but because a document was lacking a signature, they say that they received my application on November 24th, once the signature was provided. Because your file wasn't transferred until February 24th, I'm guessing your official "application received" date is sometime between Oct 8th and February 24th, but I could be wrong. What I've noticed is that they go by the application received date, and I think Mekus' November 3rd application was the closest to November 24th that I've seen PPR'd to date. I hope this makes sense.
