Please explain how the rules I mentioned no longer apply.
In term of legalities, make yourself aware of the explosive storage regulations (non-ferrous container for explosives, primers separated from powder, container clearly marked to contain explosives).
"non-ferrous container for explosives"
I assume you are referring to the old requirement of a wooden box.
No longer required and there is no mention of type of container now, except "original packaging".
"primers separated from powder" - Not in a dwelling, but it is required in a storage unit (which isn't the cabinet in your house).
"container clearly marked to contain explosives" - Not required in a dwelling. In a storage unit, there is a "fire hazard sign" requirement.
Except, you could say that 305, 2c fits what you said, but I don't believe what you meant.
If they have to be in original packaging, then of course it will be labelled. There is no additional requirement for your own labels.
The relevant current dwelling requirements are:
281. (1) When small arms cartridges
are stored in a dwelling, they must be
stored away from flammable substances
and sources of ignition. People not authorized
by the user must not be given unlimited
access to the cartridges.
299. (1) Percussion caps must be stored
in their original packaging.
Note: These Regulations do not limit the
number of percussion caps that may be
stored in their original packaging in a
dwelling or a *storage unit.
(2) Smokeless powder must be stored in
its original container or in small arms cartridges.
(3) Black powder must be stored in its
original container, in small arms cartridges
or in black powder cartouches.
304. (1) When propellant powder, percussion
caps or black power cartouches are
stored in a dwelling, they must be stored
away from flammable substances and
sources of ignition. People not authorized
by the user must not be given unlimited access
to the propellant powder, percussion
caps or black powder cartouches.
305. (2) A person who manufactures small
arms cartridges or black powder cartouches
must ensure that the following requirements
are met:
(c) all containers of explosives must be
labelled to identify their contents and
must be kept closed when not in use;
