Fundamental differences in gun culture are to blame for the predicament of a U.S. man charged with trying to smuggle a gun into Canada, the man's lawyer argues.

Bruce Engel's client Louis DiNatale claims he and his wife were heading to Vermont from their home in Kentucky last September when an accidental detour led them to the Canadian border.

That detour is now costing the couple thousands of dollars and garnering media attention throughout Canada and the U.S. — and it could mean jail time in Canada for DiNatale.

All because of what many Americans consider a right: his possession of a gun.

"Everybody and his neighbour in the U.S. either own a gun or carry a gun," Engel, DiNatale's lawyer, told CBC Radio's As It Happens.

"It's just that culture. It's very different than in Canada."
