The final price tag on the huge addition that transforms Casino Windsor into Caesars Windsor is CAD 439 million, says Kelly McDougald, the new CEO of the Ontario Lottery and Gaming Corp. "That's as of yesterday," McDougald said Thursday as she prepared to travel to Windsor to take part in the first public tours of the new building on Friday. The new casino opens officially Thursday with a gala party for thousands of invited customers and other guests from all over North America.
