Thanks a lot ES. My apologies for expecting a quick answer.
My idea behind asking those questions was to decide if could plan a very short trip (about 2-3 weeks) outside Canada. However, I am still not decided on this.
Three options that I have is 1) I go as soon as I file and utilize the time before the processing starts 2) to wait till I receive the confirmation that the file has come in process or returned 3) Don't go at all.
With Bill C-24 in action, if for some reasons the file gets returned (missing information/document) the time lost (2-3 months) will be very crucial. Since nobody knows for sure until now when are the clauses coming in effect.
