From CBC Nova Scotia:

Some Nova Scotians are driving to New Brunswick to stock up on cheaper beer as NB Liquor is looking to to compete against low prices this summer from another neighbouring province, Quebec.

New Brunswick's liquor corporation is hoping to keep New Brunswickers buying in New Brunswick with a promotion that is selling 60 cans of beer for $75 instead of $112.
