Donut Diner
Donut Diner was a Canadian coffee and doughnut franchise with locations and kiosks in and around the Niagara Region and greater Golden Horseshoe areas of Ontario. History. It was established in 1988 in St. Catharines, Ontario and grew to 30 outlets in the Niagara Peninsula. It was renowned for its old fashioned style of baked goods, its 1950s-era decor, and unique local flavour until the chain went bankrupt in 2005. All corporate owned locations closed that year, while franchised locations remained opened being allowed to continue to use the name Donut Diner without corporate support. Over the  years many franchised locations have closed and very few locations remain. Avondale Food Stores Limited, a partner of The Donut Diner, still sells and promotes its coffee in some of their convenience stores. At its peak, all Donut Diner locations were open 24 hours a day and was a major competitor to national donut giant Tim Hortons in Niagara and the Greater Toronto Area of Ontario. The Donut Diner corporate offices were located in St. Catharines, Ontario. There were approximately 50 operational franchises and at least a dozen kiosks in the Golden Horseshoe.
