About our fees
These fees allow the Canadian Coast Guard to recover the cost of maintenance dredging of the St. Lawrence Ship Channel to support commercial navigation.
The fees apply to vessels on a per transit basis, where transits meet all of the following criteria:
- begin, stop or end at a Canadian port
- the vessel has a draught of 5 metres or more
- include all or part of the St. Lawrence Ship Channel
Your vessel does not pay the dredging fees if it:
- stops at a Canadian port for 1 or more of the following sole purposes:
- respond to a medical emergency
- undertake emergency ship repairs
- respond to a government department or agency request to stop
- take on bunkers that will be used exclusively to continue their voyage
- make an overnight stop due to the seasonal removal of lighted aids to navigation
- moves within the boundaries of a port on the St. Lawrence Ship Channel
- travels through Canadian waters to or from a port in the United States, without stopping at a Canadian port
- begins its transit at the Port of Montréal (not including the terminal at Contrecœur) and proceeds directly into the St. Lawrence Seaway
- ends its transit at the Port of Montréal (not including the terminal at Contrecœur) after proceeding directly from the St. Lawrence Seaway
Rates (April 1, 2022 to March 31, 2023)
Vessels pay a per transit fee of $0.0524 multiplied by the vessel’s gross tonnage. The minimum amount charged will be $25 per transit.
The fee rate is adjusted annually for inflation on the first day of April, based on the Consumer Price Index.
The owner/operator is responsible for establishing the tax status of a vessel with regard to:
- Quebec sales tax (QST)
- provincial sales tax (PST)
- harmonized sales tax (HST)
- goods and services tax (GST)
Contact the Canada Revenue Agency for information and advice.
The goods and services tax is applied if the owner/operator of either a Canadian or foreign flag vessel is a Canadian resident.
The goods and services tax isn’t payable if the owner/operator of either a Canadian or foreign flag vessel is not a Canadian resident. In this case, shipping agents or responsible entities must submit a goods and services tax declaration form.
Owners/operators may also be eligible for Quebec sales tax exemptions if the owner/operator is not:
- a resident in the Province of Quebec
- registered with Revenue Quebec for QST purposes
In this case, shipping agents or responsible entities must submit a Quebec sales tax declaration form.
For information on tax declaration forms, please contact the Marine Services Fees Billing Collection and Compliance office.
Invoicing and payments
Our billing, collection and compliance office identifies and invoices vessels on a per transit basis. The fee is applied to the vessel and is normally payable by the entity that has control of the vessel at the time of transit, such as the:
- shipping agent
- ship owner or operator
You must pay the fee within 30 days of the invoice date. Send your fee payment to the accounting hub along with a copy of the invoice either by email, fax or post.
Interest is charged on overdue accounts as of the 31st day after the invoice date. This charge is compounded monthly, at the average Bank of Canada rate for the preceding month, plus 3%.
Vessel operators will receive a statement of account from the Fisheries and Oceans Canada accounting hub on a monthly basis, detailing all related transactions.
