"Sure" is what "Roger" sounds like when the controller says it fast. They are most certainly not saying "sure"!
In any case I did notice a regional difference with the verification in that in Eastern Canada it seems more common to get Roger, while in western Canada they all say That is Correct. Way too wordy in my opinion.
Also, when I check in with arrival and say "Gelle 3 with India", why must you repeat back "information India is current"? It is not necessary to repeat this unless it has changed to Juliet and I have now informed you my information is not current (at least I don't think so).
