Oakville, Canada – The omnichannel Tim Hortons Duelling Donuts contest kicks off July 7 and at the end of seven weeks, the creator of the next Tim Hortons menu item will be crowned — and they'll win $10,000. New this year, eight finalists will have the opportunity to defend their donut ideas in person to a panel of famous Canadians — Jason Priestley, Jann Arden, Anna Olson and Ben Mulroney.
