An individual can store firearms in four basic ways (unloaded no matter what):
1. In a room specifically designed for the safe storage of firearms. The room must be locked and not easily broken into.
2. A gun vault (ammunition may be in the same safe as long as it is not in the gun).
3. With a trigger lock.
4. With an essential operating component removed(a bolt or a bolt career)
Always go over and above what the bare minimum legal requirement is.

STORAGE OF NON-RESTRICTED FIREARMS5. (1) An individual may store a non-restricted firearm only if
(a) it is unloaded;
(b) it is
(i) rendered inoperable by means of a secure locking device,
(ii) rendered inoperable by the removal of the bolt or bolt-carrier, or
(iii) stored in a container, receptacle or room that is kept securely locked and that is constructed so that it cannot readily be broken open or into; and
(c) it is not readily accessible to ammunition, unless the ammunition is stored, together with or separately from the firearm, in a container or receptacle that is kept securely locked and that is constructed so that it cannot readily be broken open or into.
(1)(b) does not apply to any individual who stores a non-restricted firearm temporarily if the individual reasonably requires it for the control of predators or other animals in a place where it may be discharged in accordance with all applicable Acts of Parliament and of the legislature of a province, regulations made under such Acts, and municipal by-laws.
(3) Paragraphs (1)(b) and (c) do not apply to an individual who stores a non-restricted firearm in a location that is in a remote wilderness area that is not subject to any visible or otherwise reasonably ascertainable use incompatible with hunting.
