Canadian province Ontario is leading the move toward lightweight bottling by setting a maximum weight on the wines it approves. The state-controlled Liquor Control Board of Ontario (LCBO) has said it will not stock any wines packaged in a bottle weighing more than 420g from 1 January 2013. In a letter seen by Decanter, Bob Downey, sales and marketing senior vice president for LCBO, says: 'The maximum glass weight will be 420 grams for wines packaged in non-hock 750 ml bottles at or below a retail price of CAN$15.'
