Arriving in Canada means going straight to an officer at a port of entry, with no detours. Cross somewhere that is not an official crossing and you are required to head to the nearest one immediately to be examined. If another country turned you away and sent you back, you are treated as arriving fresh and get examined again.
(1)Unless these Regulations provide otherwise, for the purpose of the examination required by subsection 18(1) of the Act, a person must appear without delay before an officer at a port of entry.
(2)Unless these Regulations provide otherwise, a person who seeks to enter Canada at a place other than a port of entry must appear without delay for examination at the port of entry that is nearest to that place.
(3)For the purposes of section 18 of the Act, every person who has been returned to Canada as a result of the refusal of another country to allow that person entry is a person seeking to enter Canada.
