For ocean transshipments, will the 24 hours filing time frame correspond to the initial port or transshipment port? And what do you do if the information changes (e.g. sub-locations, vessel details) after cargo arrives at the transshipment point?

The marine timeframes refer to the last port of departure before the goods leave for a Canadian port. (So, yes 24 hours prior to loading at the last transshipment port before Canada.) eHBL data and Close Message data can be corrected / changed with an electronic Correction after sailing and before Reported (CACM) or Arrived (WACM).
