Practice Relating to Rule 51. Public and Private Property in Occupied Territory
Section B. Immovable public property in occupied territory
Canada’s LOAC Manual (1999) provides that, in occupied territory:
Enemy public immovable property may be administered and used but it may not be confiscated.
Real property belonging to the State which is essentially of a civil or non-military character, such as public buildings and offices, land, forests, parks, farms, and mines, may not be damaged unless their destruction is imperatively demanded by the exigencies of war. The occupant becomes the administrator of the property and is liable to use the property, but must not exercise its rights in such a wasteful or negligent way as will decrease its value. The occupant has no right of disposal or sale.
Public real property which is of an essentially military nature such as airfields and arsenals remain at the absolute disposal of the occupant. 
Canada, The Law of Armed Conflict at the Operational and Tactical Level, Office of the Judge Advocate General, 1999, p. 12-8, § 69 and p. 12-9, §§ 80 and 81.
Canada’s LOAC Manual (2001) states in its chapter on rights and duties of occupying powers:
1238. Confiscation
1. Confiscation is the taking of enemy public movable property without the obligation to compensate the state to which it belongs. All enemy public movable property which may be usable for military operations may be confiscated. Private property may not be confiscated. Enemy public immovable property may be administered and used but it may not be confiscated.
1243. Real Property of the State
1. Real property belonging to the State which is essentially of a civil or non-military character, such as public buildings and offices, land, forests, parks, farms, and mines, may not be damaged unless their destruction is imperatively demanded by the exigencies of war. The occupant becomes the administrator of the property and is able to use the property, but must not exercise its rights in such a wasteful or negligent way as will decrease its value. The occupant has no right of disposal or sale.
2. Public real property, which is of an essentially military nature such as airfields and arsenals remain at the absolute disposal of the occupant.
