    1. Optional Annexes In accordance with article 14 of the Convention Canada declares that it does not accept Annexes III, IV and V of the Convention at this time. 2. Arctic waters Canada makes the following declarations based on Article 234 of the 1982 United Nations Convention on the Law of the Sea, signed by Canada on 10 December, 1982: (a) The Government of Canada considers that it has the right in accordance with international law to adopt and enforce special non-discrimination laws and regulations for the prevention, reduction and control of marine pollution from vessels in ice-covered waters where particularly severe climatic conditions and the presence of ice covering such waters for most of the year create obstructions or exceptional hazards to navigation, and pollution of the marine environment could cause major harm to or irreversible disturbance of the ecological balance. (b) Consequently, Canada considers that its accession to the Protocol of 1978, as amended, relating to the International Convention for the Prevention of Pollution from Ships, 1973 (MARPOL 73/78) is without prejudice to such Canadian laws and regulations as are now or may in the future be established in respect of arctic waters within or adjacent to Canada.

    Objections Italy, 30-01-1984

    ... The Italian Government objects to the reservation on the part of France as specified in document PMP/Circ. 15 of the 13th August, 1982. Said reservation is contrary to the spirit and the letter of rule 10, Annex I, of the above mentioned Convention in relation to paragraph 2 as well as paragraph 7 which makes the construction of collecting devices in the categories of ports specified in the document compulsory. Moreover the French reservation sets up a facultative trend where binding provisions exist, as per Annex I of the MARPOL Convention 1973/78, and would appear to be incompatible with the Italian legislation on the subject which lays down very restrictive principles.

    Objections Sweden, 23-07-1983

The Swedish Government therefore, is unable to accept the declaration made by the French Government.
