Border officials say two prohibited handguns seized at the Windsor-Detroit Tunnel earlier this month were destroyed.
The Canada Border Services Agency said a 9mm Taurus G2C handgun, a 9mm CPX-2 handgun and a 12-round capacity magazine were seized on June 4.
The owner wasn't charged but did have to pay a $2,500 fine before they could return to the U.S.
The handguns and the magazine are prohibited in Canada, and CBSA Senior Spokesperson Judith Gadbois-St-Cyr said the agency takes its responsibility to keep contraband and weapons out of the country very seriously.
"Canadian firearm laws are clear. All travellers must declare any firearms in their possession when they enter Canada," she said. "Travellers who do not declare firearms upon arrive can face arrest, seizure, monetary penalties, or criminal prosecution."
Last year, the CBSA seized 166 firearms at border crossings in Southern Ontario. The Detroit Field Office of the U.S. Customs and Border Protection Agency, which oversees the Ambassador Bridge and the Windsor-Detroit Tunnel in Windsor, the Bluewater Bridge in Sarnia, the International Bridge in Sault Ste. Marie and the Detroit Metropolitan Airport seized 181.
