The winning ticket in last night's Lotto Max draw was sold in Edmonton, the Western Canada Lottery Corporation says.

The corporation said the one lucky ticket is worth about $50 million dollars. 

Four winning tickets for prizes of $231,287.40 were also purchased in Calgary, Saskatchewan and Ontario.

The big multimillion-dollar prize has gone unclaimed for the past four weeks.
