In Canada, the Marine Liability Act[1] (MLA) is the main source of legislation that limits damages in the maritime context. The MLA incorporates various international conventions into law and adds some uniquely Canadian features.

Limitation convention

The Convention on Limitation of Liability for Maritime Claims, 1976 (as amended by the Protocol) is incorporated in part 3 of the MLA. The right of the shipowner to limit liability after a maritime incident is 'virtually unbreakable'[2] in Canada. The limits of liability in Canada for property claims are as follows:[3]

Gross tonnage

Limit of liability ($)

Ships less than 300

500,000

Ships between 300 and 2,000

2.72m

Ships between 2,000 and 30,000

+1,086 more per tonne

Ships between 30,000 and 70,000

+815 more per tonne

Ships above 70,000

+543 more per tonne

The limits of liability in Canada for personal injury claims are as follows:[4]

Gross tonnage

Liability limit ($)

Ships less than 300

1m

Ships between 300 and 2,000

5.43m

Ships between 2,000 and 30,000

+2,172 more per tonne

Ships between 30,000 and 70,000

+1,629 more per tonne

Ships above 70,000

+1,086 more per tonne

Passenger claims

Part 4 of the MLA incorporates most of the provisions of the Athens Convention into Canadian law for the injury or death of fare-paying passengers. The MLA extends the application of the Athens Convention to domestic and inland voyages. The limit for the personal injury or death of a passenger is 175,000 units of account.

The Canadian commercial purpose person

Part 4 of the MLA extends the application of the Athens Convention beyond paying passengers to those aboard a vessel that is 'operated for a commercial or public purpose'. [5] The determination of circumstances falling under this extension can have significant consequences due to the lower limits under the Athens Convention. In Gundersen v Finn Marine,[6] a non-paying guest of the captain on a water taxi was seriously injured after the captain fell asleep at the helm and ran aground. The court held that the Athens Convention applied under the commercial purpose category,[7] and therefore the guest's damages were limited to 175,000 special drawing rights (SDR).

Cargo claims

Canada is a Hague–Visby state. Part 5 of the MLA incorporates the Hague–Visby Rules (HVR) into the law of Canada. The MLA makes the HVR applicable only to carriage of goods governed by a negotiable bill of lading. In addition, Canada has an exception for negotiable bills of lading whereby the claimant can sue in Canada for a loss despite any jurisdiction clause in a bill of lading if:

  1.  the actual port of loading or discharge, or the intended port of loading or discharge under the contract, is in Canada;
  2.  the person against whom the claim is made resides or has a place of business, branch or agency in Canada; or
  3.  the contract was made in Canada.[8]

Pollution

Part 6 of the MLA incorporates the Civil Liability Convention and the Bunkers Convention into the law of Canada. The strict liability regime of those conventions applies, including any restrictions on entitlement to limit.

For bunkers, the limits of liability are as follows:

Gross tonnage of vessel

Limit of liability ($)

Ships not exceeding 300

500,000

Ships not exceeding 2,000

2.72m

Ships between 2,000 and 30,000

Up to 33.57m

Ships between 30,000 and 70,000

Up to 66.59m

Ships above 70,000

+504 more per tonne

For tankers, the limits of liability are as follows:

Gross tonnage

Limit of liability (SDR)

Up to 5,000 gross tons

4,510,000

Above 5,000 gross tons

631 SDR per additional unit of tonnage up to a maximum of 89,770,000

Commercial trucking claims and limits

Although Canadian maritime law falls under federal jurisdiction and is applied uniformly nationwide, the regulation of commercial transportation is regulated by each of Canada's ten provinces and three territories. In Canadian common law, motor carriers that hold themselves out to the public ('common carriers') are subject to strict liability. This liability is subject to only certain defences, such as force majeure-type events or inherent defects. To encourage the industry, most (but not all) Canadian provinces and territories regulate limits of liability for commercial trucking.[9] For most of Canada, the limit of liability is therefore $4.41 per kilogram ($2.00 per pound). A key question is which province's law governs a given contract, as some provinces and territories have unique limits or no limits at all. The application of regulatory limits by courts across Canada is somewhat inconsistent as well, and often depends on the specific facts of a given case.
