The Globe and Mail reports in its Friday edition that the daughter of hockey star Tim Horton has retired as a franchisee in the coffee chain that bears his name, urging her peers to "keep demanding better" as declining profitability has led to tensions with parent company Restaurant Brands International. The Globe's Susan Krashinsky writes that in a letter sent to fellow franchisees, Jeri Horton-Joyce announced her retirement effective May 31. She owned three Tim Hortons locations in Cobourg, Ont., and one in nearby Colborne, Ont. Recently, Ms. Horton-Joyce was part of the board of the Alliance of Canadian Franchisees (ACF), an independent group representing some disgruntled Tim Hortons franchisees. The ACF board resigned in March after RBI sent default notices to board members. RBI also terminated the franchise contract of its president, Ron Fox. The board members had only been in their roles for a short time after the ACF appointed a new executive director the previous fall. The group had raised concerns in February about falling profits at Tim Hortons, a problem the parent company's executives have said is a priority to address. Ms. Horton-Joyce did not attribute her retirement decision to the recent tensions.
