I have a distantly related question regarding temporary stay in Canada. My parents just gave their biometrics yesterday in the US (CPC-M is processing their case). When we entered the border at the Douglas crossing, the CBSA officer, for whatever reason, asked when they are leaving and, if so, why. I explained they intend to stay here to await the finalization of the the PGP application, but he seemed to insist they ought to leave Canada before their 6-mo stay expiry in October. I don't understand why, if they left Canada and re-entered (same-day). Doesn't that count as a reset of the 6-month counter, so to speak?
