Canadian Coast Guard Marine Communications and Traffic Services have been using all Canadian Hydrographic Service water-level stations for the calculation of passage authorizations in the Sorel–Montreal sector of the navigational waterway, namely Sorel, Contrecoeur, Varennes, Montreal-Frontenac and Montreal-Jetty No. 1.

In light of the particular features of the navigational waterway in the portion between buoys M84 (downstream of the municipality of Verchères) and M11 (downstream of the Bellmouth curve), it was agreed to adjust upward the available water column by 10 cm in this portion.

The minimum water column in this portion of the navigational waterway as per the Contrecœur hydrographic station, obtained after adjustment, will be used for the calculation of under-keel clearance.

In light of the particular features of the navigational waterway in the portion between buoys M84 (downstream of the municipality of Verchères) and M157 (opposite to the Port of Montreal, section 109) as well as the No. 1 Anchorage Pointe-aux-Tremble, it was agreed to adjust upward the available water column by 10 cm in this portion.

The minimum water column in this portion of the navigational waterway as per the Varennes hydrographic station, obtained after adjustment, will be used for the calculation of under-keel clearance.

Caution

Effective 190400 UTC Jul 2024, in order to promote navigation safety and protection of the marine environment due to an increased presence of North Atlantic right whales, a speed restriction area has been established and applies to all vessels that are more than 13m in length overall:

Northern Static Zone: Vessels are instructed to proceed at a speed not exceeding 10.0kts over the ground.

Southern Static Zone: Vessels are instructed to proceed at a speed not exceeding 10.0kts over the ground.

Dynamic Shipping Zone A: There are no speed restrictions in effect.

Dynamic Shipping Zone B: There are no speed restrictions in effect.

Dynamic Shipping Zone C: There are no speed restrictions in effect.

Dynamic Shipping Zone D: There are no speed restrictions in effect.

Dynamic Shipping Zone E: There are no speed restrictions in effect.

Seasonal Management Area 1: There are no speed restrictions in effect.

Seasonal Management Area 2: There are no speed restrictions in effect.

Restricted Area: Vessels are prohibited from transiting through the area unless they are included in the exception list under Transport Canada's Interim Order for the Protection of North Atlantic Right Whales in the Gulf of St. Lawrence, 2024. The excepted vessels are instructed to proceed at a speed not exceeding 8.0kts over the ground.

Voluntary Seasonal Slowdown Zone: There is no voluntary slow down in effect.

Details, including all geographical coordinates, are available in Notice to Mariners 401/24 and are available upon request from a Marine Communications and Traffic Services Centre. Failure to comply with this speed restriction could lead to enforcement action by Transport Canada.

Mariners are requested to report all whale sightings and observations of entangled, dead, or injured whales to the nearest Marine Communication and Traffic Services Centre.
