What do you do in this particular case? This person was at a land crossing between Canada and US and Canada already denied entry first. I am pretty sure the law does not have an option of "be escorted to the nearest international airport/exit at deportee's cost", but in this case, having an option to leave yourself in 48h or face even harsher bans would have likely worked.
