Could your truck be considered a storage unit?
Explosive Regulations define a storage unit as "storage unit means a building, structure, place or container in which explosives are stored and that is not licensed. However, it does not include a dwelling or any structure, place or container in a dwelling. (unité de stockage)

For transporting small amounts of small arms cartridges as a user only the follow applies as per the explosives regulations.
Part 9 -186 ...When a small quantity of certain explosives
is to be shipped, the requirements of
section 190 apply.
Part 9 - 190.2 ... "However, the carrier and driver must
ensure that the explosives are transported
in a package or container that is designed,
constructed, filled, closed, secured and
maintained so that under normal conditions
of transport the likelihood of an ignition is
minimized."
Regarding storage,most users I know choose to store in their dwelling and only the following would apply;
Part 14 - 281. (1) ... When small arms cartridgesare 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.
NOTE: You would need to the consult the Firearms Act for firearms storage requirements if storing with ammunition.
