There is one small holdout in Southern Alberta where prohibition of liquor is still in effect. Consumption isn't prohibited, but the sale of liquor is. There was even a recent plebiscite where the locals voted to maintain prohibition, so the Town cannot apply for a license, and no one can sell booze inside the prohibited area. Prohibition is legislated at the Provincial level. The Minister has to raise prohibition before any municipalities without a license can hold a plebiscite to get a license, but the Minister won't raise prohibition unless there is support from the community.
It's illegal to sell liquor inside the prohibited area, but is it illegal to to deliver liquor to a prohibited area? There is nothing in the Town bylaws that specifically address this (yet), but prohibition isn't at the local level, it's at the provincial level. If a delivery service were to warehouse their inventory outside of the prohibited area, and transact over the phone using credit cards, could they still deliver liquor to customers inside the prohibited area?
