OTTAWA -- Stephen Harper says laws that prohibit people from taking alcohol across provincial borders are "ridiculous."

He says that's why the Conservative government brought in legislation allowing the practice -- a private members bill nicknamed

"Free My Grapes" became law in 2012.

But it requires legislation at the provincial level as well and not all provinces have signed on.

Harper was asked about the issue at a campaign rally today, following the end last week of a New Brunswick trial on the issue.

Gerard Comeau was charged with illegally importing 14 cases of beer and three bottles of liquor from a Quebec border town in October 2012 and fined close to $300.

His lawyers argue the law is unconstitutional, but the judge isn't expected to rule until next year.

Harper, known more for his fondness for soft drinks than for alcohol, urged provinces to rethink their laws.

"My personal view and the view of our government is that's ridiculous," Harper said of the ban.

"That's why we brought in federal legislation that does require mirror legislation at the provincial level, a couple of provinces have proceeded with similar legislation, not all have.

"But obviously I would in my campaign mode, non-partisan way, urge all provinces to adopt that legislation."
