@ shoreToShip.......
Re proposed deep water container terminal in Quebec City....I am not familiar with the Laurentia/Hutchison project. In regards to CN and Saint John, they have always serviced local port (via Moncton). It was actually CP Rail returning to Saint John after a 35 year absence. (CP sold off it's operations in the Atlantic region in the 1990's). In 2020 CP purchased the Central Maine & Quebec RR giving them greater access to eastern USA markets and Upper Canada/Mid USA (See below link).

Side bar: Since 2017 DP World operate terminal in Saint John (Taking over from Logistec Corporation).
Hutchison Ports and DP World are two of the largest terminal operators in the world, ranking 4 and 5 respectively in terms of global TEU volume.

Kind regards,

@ shoreToShip...... In regards to Saint john, the port in final stages of a major expansion to their container terminal. Two new shore cranes recently arrived from Charleston, S.C..... Bodes well for future growth / increased container traffic.
PS: I am from Quebec originally. (Born in Quebec City many decades ago). I manage to return periodically and visit with friends living on the "Island"...

Typical river scene this time of year, with the ice and the "Pont de l'ile" in the background...! Very nice, "up close" shot...!

Excellent :)
