I can understand why certain foodstuffs being brought into certain countries might cause a risk to agriculture, livestock and wildlife; (a couple of years of watching Border Control daytime programmes was very enlightening on that fact).
However, I have been racking my brains trying to think of why taking in a personal usage length of corduroy fabric, as opposed to made-up corduroy trousers, might be a heinous crime in Canada, but have drawn a blank.
Can anyone enlighten us?
