Over a five day period, the Canada Border Services Agency (CBSA) is reporting that between Oct. 21-25, 2025, its officers seized five guns and two knives at the Windsor-Detroit Tunnel and Ambassador Bridge.
They said multiple over-capacity magazines were also seized.
All involved were reportedly U.S. citizens who were arrested under the Customs Act.
The CBSA said each of the five travellers were fined between $1,000 and $2,500 and returned to the U.S.
