A former ombudsman at one of Canada’s big banks has been tapped to investigate complaints of a far more frothy nature: beer. The Beer Store has appointed Charles Dougall as Ontario’s first beer ombudsman. The foreign-owned consortium, which operates more than 470 retail outlets throughout the province, says Dougall will be responsible for mediating operational disputes between the Beer Store, its customers and brewers. He has been appointed to a three-year term, beginning Jan. 2, and will report annually to the Beer Store’s independent directors.
