Practice Relating to Rule 12. Definition of Indiscriminate Attacks
Section B. Attacks which cannot be directed at a specific military objective
Canada’s LOAC Manual (1999) states:
Indiscriminate attacks are those that may strike legitimate targets and civilians or civilian objects without distinction. They are prohibited. Indiscriminate attacks are:
b. those which employ a method or means of combat which cannot be directed at a specific legitimate target according to LOAC. 
Canada, The Law of Armed Conflict at the Operational and Tactical Level, Office of the Judge Advocate General, 1999, p. 4–3, § 22(b); see also p. 5-2, § 11.
Canada’s LOAC Manual (2001) states in its chapter on targeting:
Indiscriminate attacks are those that may strike legitimate targets and civilians or civilian objects without distinction. They are prohibited. Indiscriminate attacks are:
b. those which employ a method or means of combat which cannot be directed at a specific legitimate target. 
Canada, The Law of Armed Conflict at the Operational and Tactical Levels, Office of the Judge Advocate General, 13 August 2001, § 416.1.b.
At the CDDH, Canada stated:
The definition of indiscriminate attack contained in paragraph 4 of Article 46 [now Article 51of the 1977 Additional Protocol I] is not intended to mean that there are means of combat the use of which would constitute an indiscriminate attack in all circumstances. It is our view that this definition takes account of the circumstances, as evidenced by the examples listed in paragraph 5 to determine the legitimacy of the use of means of combat.
