A new report suggests it would be foolhardy for Saskatchewan to follow Alberta or British Columbia's lead and privatize liquor stores.

The Canadian Centre for Policy Alternatives and the Parkland Institute say privatizing liquor stores has cost Alberta and British Columbia millions in tax revenue.

A report by the left-of-centre groups compared 13 beverages and found prices were higher at the private stores.

Report author David Campanella says the research should give any jurisdiction considering privatizing liquor stores reason to pause.

Alberta privatized liquor stores in 1993, while B.C. curbed expansion of publicly-owned stores and started to allow private ones in 2003.

Saskatchewan Premier Brad Wall hinted last week that all new liquor stores in the province could be privatized.
