Canada Customs officials intercepted three people in the last few months trying to bring weapons across Yukon's Beaver Creek border crossing.
In one incident, an Alaska man was charged after failing to declare several firearms in his possession.
On Feb. 15, a U.S. resident failed to declare a handgun, a loaded assault rifle and an empty 30-round magazine while trying to cross into Canada. He has been charged with two counts of smuggling, two counts of possession of a prohibited firearm with ammunition, and one count of possession of a prohibited weapon.
Another U.S. resident faces nine counts of firearms-related smuggling offences after officers found a handgun, an assault rifle and 79 prohibited ammunition magazines in his vehicle on Feb. 24.
Canada Border Services Agency says the law is clear — all persons crossing the border must declare weapons in their possession.
