Ammunition
Both Canadians and non-residents may import sporting and competitive ammunition for their personal use, but if they want to import hollow-point ammunition labelled for use in handguns, they need written authorization from Natural Resources Canada.
Canadian residents do not need a permit from Natural Resources Canada to import:
small arms sporting ammunition up to a maximum of 5,000 rounds;
percussion primers, up to a quantity of 5,000;
empty primed cartridge cases, up to a quantity of 5,000; and
propellants (smokeless and black powder), up to a maximum of 8 kilograms, (17.66 pounds).
Within these limits, non-residents can import 200 rounds duty free for hunting purposes, or up to 1,500 rounds duty free for use at a recognized competition.
You can make arrangements to import larger quantities through a Canadian shooting association, committee, or federation for team practice and competition at meets. For information on permits to import quantities of ammunition in excess of those mentioned above, contact:
