Ship clearance times for Canada / New England ports

[InsideCruiser]

Does the ship need to wait for customs clearance if it hasn't crossed a border since the last port?

 

Itinerary:

• August 27, 2015 - Bayonne, New Jersey 4:00 PM
  
• August 28, 2015 - At Sea
  
• August 29, 2015 - Boston, Massachusetts 7:00 AM
  
• August 30, 2015 - Portland, Maine 8:00 AM
  
• August 31, 2015 - Bar Harbor, Maine 7:00 AM
  
• September 01, 2015 - St. John, New Brunswick 11:00 AM
  
• September 02, 2015 - At Sea
  
• September 03, 2015 - Halifax, Nova Scotia 7:00 AM
  
• September 04, 2015 - At Sea
  
• September 05, 2015 - Bayonne, New Jersey 7:00 AM
  

 

Clearly we will need to wait for clearance from Canada Customs when arriving in St. John so I'm anticipating an 11:30 AM clearance.

 

But I figured we would be cleared upon arrival in Boston, Portland, Bar Harbor, and Halifax since we haven't crossed a border.

 

But I ran across these compasses from a 2014 Brilliance cruise. Day 5 shows them arriving in St. John at 5:30 AM and being cleared at 6:00 AM even though they are travelling from Halifax and haven't crossed a border.

 

Does the ship need to clear customs at each port regardless of where it arrives from? Or perhaps the Halifax / St. John trip around Nova Scotia passes through US or International waters?

 

Thanks for any insight,

you only clear customs the first stop. After that they just need clearance from the port authority which is quick.
