Pilot Project – Guidelines for the Transit of Container
Vessels up to 310 metres in Length x 40 metres in Beam –
Québec–Montréal Segment
*1001/25Pilot Project – Guidelines for the Transit of Container Vessels up to 310 metres in Length x 40 metres in Beam – Québec–Montréal Segment
NOTICE
This notice sets out the conditions under which container ships,
with a maximum length of 310 metres and a beam of up to 40
metres, may safely transit the St. Lawrence waterway between
Québec and Montréal.
Effective Date: September 30, 2025
Duration: This pilot project remains in effect
until further notice or until permanent guidelines are
established.
Scope of the Pilot Project
This pilot project applies to container vessels with following dimensions:
Length Overall: Between 300.01 metres and not exceeding 310.0 metres; and,
Moulded Breadth: Equal to or greater than 32.5 metres, not exceeding 40.0 metres.
Application of Notice to Mariners 27A
Notice to Mariners 27A remains applicable, except for the following sections, which are amended or replaced by the directives specified in this pilot project:
Section 2: Meetings in Risk Areas (R)
Section 3: Overtaking in Risk Areas (D)
Section 6: Maneuverability Assessment
Note: Any changes in the status of the vessel (e.g. hull, navigational equipment, propulsion, etc.) must be reported immediately to the Escoumins Marine Communication and Traffic Services Centre (MCTS Escoumins) prior to entering pilotage area.
Should a deficiency occur, it will be analyzed and reviewed by Canadian Coast Guard, Pilotage Authority and Transport Canada to determine steps to resolve the issue. A reauthorization will be required to proceed into pilotage areas as a vessel participating in a pilot project.
Specific Guidelines – Container Ships up to 310 m x 40 m
1. Meetings and Overtaking
All meetings and overtaking are permitted in accordance with Notice 27A for all vessels, except for Wide Beam and Long vessels.
For these vessels, the authorized zones for meeting and overtaking with vessel up to 310 m x 40m will be determined by the expert committee and communicated to MCTS within 48-hours prior to the transit, based on scheduled traffic of other Wide Beam and Long vessels.
2. Transit Safety Conditions and Measures
2.1 Transits will mostly occur during daylight between Québec and Montréal, depending on weather, traffic, and other navigational risk factors.
2.1.1 During hours of darkness, in favourable
conditions, passage is allowed for upbound container vessels
until Grondines.
2.1.2 The “Good Manoeuvrability” (BM)
classification, as defined in Sections 6 and 7 of Notice 27A,
cannot be assigned to the vessels covered by this pilot
project.
2.2 Minimum engine speed is required when approaching the Québec bridges and the Laviolette Bridge, provided environmental conditions allow.
2.3 Maximum speed over ground between
Île-aux-Vaches and Contrecoeur is 9 knots upbound and 11 knots
downbound.
2.4 During pilot changeovers at
Trois-Rivières, the handover of conduct shall take place,
upstream or downstream after the vessel has cleared the
Laviolette Bridge, weather conditions permitting.
2.5 At least 30 minutes before passing under
the Québec bridges and the Laviolette Bridge, qualified crew
members must be stationed:
•In the steering gear room, ready to activate emergency steering systems; and,
•On the forecastle, ready to drop anchors.
Each station must be equipped with independent communication
means with the bridge.
2.6 An operational tug with a minimum bollard
pull of 40 tonnes must be assigned and available during the
vessel’s transit under the Laviolette Bridge. The tug must:
•Be within a 15-nautical-mile radius of the Laviolette Bridge;
•Ready to respond within one hour’s notice
Passage Management Framework
1. Coordination and Follow-up Procedures
Any shipowner or agent planning a transit under this pilot
project must notify the Laurentian Pilotage Authority (LPA) at
transit@apl.gc.ca as
soon as possible, and at least 10 days in advance.
2. Expert Committee
The expert committee responsible for monitoring this pilot
project consists of representatives from:
•Canadian Coast Guard (CCG)
•Corporation of Central St. Lawrence Pilots
(CPSLC)
•Laurentian Pilotage Authority (LPA)
•Montreal Port Authority (MPA)
•Transport Canada (TC)
Roles and Responsibilities:
•Pre-transit assessment: Hold a meeting
before each transit to analyze environmental, operational, and
safety conditions.
•Transit Planning: Coordinate vessel
arrival and ensure measures are implemented.
•Transit monitoring: Oversee and study
each transit
•Decision-making: Authorize or postpone passage based on observed conditions and evaluated risks.
3. Operational Flexibility
The expert committee may:
•Ease, reinforce, or modify safety measures based on weather, tides, or other risk factors.
•Place representatives on board for study and verification purposes within the pilot project.
Safety and Responsibility Clause
In applying these guidelines, it is understood that the pilot and
bridge team must take into account all navigational hazards,
collision risks, and special circumstances, as well as vessel
limitations, which may require deviation from these measures to
avoid immediate danger.
In such cases of deviation, or in any incident or situation,
the pilot must inform the nearest MCTS officer.
The pilot conducting the vessel is responsible to the master
for the safety navigation of the vessel.
(Section
38.01(3) of the Pilotage Act)
Pilot Project Progress
As part of this pilot project, safety measures will be continuously monitored and may be progressively adjusted by the expert committee based on:
•Operational experience acquired during transits under
varied conditions;
•Results of complementary technical studies;
•Assessment of the potential impact on traffic fluidity;
and,
•Recommendations made by the expert committee.
Any adjustment must be submitted to the Standing Committee on Navigational Safety (SCNS) for review and, if required, communicated through additional notices.
Reporting and Data Collection
After each voyage, pilots must submit to the expert committee a
detailed report on vessel maneuverability and on meetings that
occurred during the passage. MCTS will also submit a transit
report.
The Laurentian Pilotage Authority will maintain a consolidated
database of all transit and maneuverability reports related to
this pilot project.
