The new Tim Hortons museum that commemorates the chain's remarkable 50 year history will host a grand opening party on Wednesday at the Ottawa Street location in Hamilton where it all started.

Coffee and donut lovers are invited to the original store from 10 a.m. to 2 p.m. to celebrate with free coffee served in retro cups, and 1,500 throwback donuts being served to the public and to take a tour of the attached museum.

The celebrations include a ribbon cutting ceremony featuring Tim Horton's daughter, Teri Horton-Joyce and Hamilton Mayor Fred Eisenberger.

Players from the Hamilton Tiger Cats will also be at the store signing autographs, says Tim Hortons manager Kevin Kisil.
