Sault Ste. Marie Locks and Canals

Opening of the Sault Ste. Marie Locks (U.S.A.) is currently scheduled for March 25, 2018. Please note the Notice to Navigation Interests released by the U.S. Army Corps of Engineers for further information.

Allowable Draft

In the Montreal / Lake Ontario Section, the maximum allowable draft will be 80.0 dm (26’ 3”) until the South Shore Canal is ice-free or April 15th, whichever occurs first, at which time, if water levels are favorable, the maximum draft will be increased to 80.8 dm (26’ 6”) for all vessels.

Mariners are reminded that for ships loaded to a draft greater than 80.0 dm (26’ 3”), speeds will be monitored carefully between St. Lambert Lock and St. Nicolas Island.

In the Welland Canal, a maximum allowable draft of 80.8 dm (26’ 6”) will be in effect from the start of the navigation season for all vessels.

Please note that, for vessels loaded to a draft greater than 80.0 dm (26’ 3”), speeds will be monitored carefully between the upper entrance to Lock 7 and former Bridge 12 in order to reduce bank erosion in this area.

Vessels equipped with an approved and operational draft information system will be permitted to transit at a draft of up to 7cm above the maximum allowable draft.
