The Montreal Port Authority (MPA) is always evaluating the state of its infrastructures, which are vital for the Port’s ongoing operational activities. It does so by working closely with its partners.

In constant preventive mode, the Port of Montreal team managed to weigh one of these three marine transfer towers at the grain terminal. Weighing it made it possible to validate the real load supported by the 40 wheels at the tower base.

A Port team headed by Stéfan Simard, a dock engineer, conducted a series of analyses and technical verifications on the transfer towers, thereby contributing to the lifting success of this impressive structure that makes up the marine towers. It is worth remembering that their role is to unload grain from the vessels docked at Berth 56. Each tower is about 61 metres high, making them as tall as new observation wheel, the Grande Roue de Montréal!

Carrying out this project required the collaboration of several stakeholders, such as Urgence Marine and Viterra, the terminal operator.

The results confirmed the stability of Berth 56 and accurately evaluated the load supported by each of the 40 wheels on a marine tower.


The MPA’s grain terminal is a grain elevator managed by Viterra. This terminal is connected to the CN and CP rail networks by our own rail network. It ensures the continuity of bulk grain provision through direct sea routes to various destinations in Canada, the United States and Europe.
The year 2016 was a record year for grain, with more than 4.6 million metric tonnes handled at our terminal. The large vessel loading capacity makes the Port of Montreal’s grain elevator one of the fastest and most efficient on the St. Lawrence River. Our year-round operations and capacity to accommodate unit trains enables our facility to maintain links with international markets at all times.
