Advocates of removing trade barriers that prevent citizens from moving more than small amounts of alcohol across provincial borders say they are cautiously optimistic about a line in Tuesday鈥檚 federal budget.

The budget states: 鈥淭o facilitate internal trade, the Government intends to remove the federal requirement that alcohol moving from one province to another be sold or consigned to a provincial liquor authority. Provinces and territories would continue to be able to regulate the sale and distribution of alcohol within their boundaries.鈥�

Derek From, staff lawyer at the tells CTVNews.ca that although 鈥渢he devil is in the details鈥� the proposal 鈥渟ounds very promising.鈥�

At present, the prohibition-era states that liquor can鈥檛 cross provincial boundaries 鈥渆xcept such as has been purchased by or on behalf of, and that is consigned to Her Majesty or the executive government of, the province into which it is being imported.鈥�

This is likely the law the Liberals are planning to change, according to From.

鈥淏est case scenario is a restaurant in downtown Toronto that wants to have access to a really nice wine in B.C., but it鈥檚 not on the shelf in any of the stores in Ontario鈥� will be able to 鈥渏ust get online and order it and have it directly shipped to them,鈥� he said.

Dan Paszkowski, president of the Canadian Vintners Association, says he believes the Liberals intend to let consumers order wines from other provinces directly to their homes, rather than going through a provincial government agency like Ontario鈥檚 LCBO or Quebec鈥檚 SAQ.

鈥淚f you ordered a case of wine from British Columbia it (currently) would have to go through the LCBO,鈥� he told CTV鈥檚 Power Play. 鈥淲ith this, you wouldn鈥檛 have to go through the LCBO -- and hopefully avoid the tax.鈥�

From said he believes the case of Gerard Comeau, whom the CCF defended at the Supreme Court of Canada, brought the interprovincial trade barriers to the public鈥檚 attention.

Comeau was fined $292.40 in 2012 for transporting several cases of beer and some liquor into New Brunswick from Quebec. He fought the ticket all the way to the supreme court and lost. The court said that provinces have the right to incidentally burden free trade with laws that have other valid purposes like protecting health or safety.

From said the change would be a win for producers and consumers. 鈥淭here鈥檚 no one who doesn鈥檛 benefit,鈥� he said.
