Tim Hortons to stage theatrical production loosely based around 2010 Sarnia, Ont., snowstorm

In the last year, Tim Hortons has treated cottaging Canadians to a boat drive thru, revived its beloved Dutchie doughnut and launched flatbread pizzas.

But perhaps its biggest surprise will come this summer, on the heels of its 60th anniversary on May 17, when it enters a realm so unexpected for a fast-food giant that even its executives expect some people's first reactions to be, "What?!"

The head-scratcher will come in the form of The Last Timbit, a musical for which Tim Hortons has assembled a who's who of Canadian artists to stage at the Elgin Theatre in Toronto this June.

The production is loosely based on a 2010 snowstorm that was so bad, drivers on a highway east of Sarnia, Ont,. were forced to hunker down in cars and others had to wait out the inclement weather at a local Tim Hortons.

Turning the story into a theatrical production was the brainchild of Gut, a marketing firm Tims hired to help it conjure up a way to celebrate its milestone year.

Among their first calls was Michael Rubinoff, a Toronto lawyer and theatre producer who turned the story of passengers on planes diverted to Gander, Nfld. after the 9/11 attacks in New York into the hit musical Come From Away.

"The Tims logo is on one of the backdrops in The Book of Mormon that people don't realize and of course, in the musical I'm involved in, Come From Away, Tims plays a really important part," Rubinoff said.

Alongside Rubinoff, other talent started flowing in. Nick Green, the playwright behind Casey and Diana, wrote the script and Anika and Britta Johnson of Life After created the music and lyrics, which include a song called What would you do for a Timbit?

The cast features Stratford and Shaw festival regulars Andrew Broderick and DeAnn deGruijter, as well as Broadway stars Kimberly-Ann Truong, Jake Epstein and Chilina Kennedy.

Most were surprised Tims, which is spending the year focused on expanding its afternoon and evening sales, was behind the play.

Once they saw the calibre of theatrical talent on board, they realized "this is going to be something that they're excited to attach themselves to," Rubinoff said.

The production comes as arts organizations have struggled to retain corporate funding. Last summer, Bell stopped funding the Toronto International Film Festival after 28 years of sponsorship.

In March, the Bank of Nova Scotia ditched its title sponsorship of the Contact Photography Festival in Toronto.

Hot Docs, Canada's largest documentary film festival, has also warned its future is in jeopardy.

Such struggles have not been lost on Rubinoff, who called The Last Timbit a "major investment."

"We only get better and we only strengthen those skills when we have the opportunities to actually do the thing, and this is the opportunity to do the thing," he said.

He's approaching the project with the same seriousness as he does any other theatrical production. There's been months of perfecting the script and table reads and soon, rehearsals will begin.

The music has already become an earworm.

"These songs have been on loop. I am telling you I can't sleep without hearing the songs," he said. "I wake up hearing the song, so I know that it's a great sign."

While he doesn't want to give away too many hints about the tunes or the play's plot, he said at the core of the storyline is a mother and daughter impacted by the storm. (The last Timbit they will vie for is a birthday one.)

And though the play is meant to mix humour and heart, he said, "nobody will dress up and dance like a Timbit, but I don't want to say no to anything."

That includes touring with the production, which will premiere in front of Tims franchisees visiting Toronto and then continue with five shows for the public. Tickets go on sale Friday.
