Exploring the history (and mystery) of Alberta's iconic Burger Baron chain in new documentary

Anyone outside of Western Canada might not know or understand the cult following behind the unassuming Burger Baron restaurant.

The popular fast-food chain, with its distinctive sign, popular mushroom burger and 25 locations around Alberta, has been a part of the Prairie dining scene since the 1950s.

But unlike most chains, all Burger Barons are independently owned. There are no franchise fees, different facades, colour schemes, branding and even menu items, save for the aforementioned mushroom burger.

Even the logo isn't consistent:Some barons are dressed in a red uniform, others in blue, and their cartoonnoses range from a dot to a circle.

"It's actually the restaurant equivalent of a public domain," Edmonton writer Omar Mouallem told CBC's Edmonton AM on Thursday.

The self-proclaimed historian of the Burger Baron chain,Mouallem is currently working on a documentary about the franchise's origins in the province called The Last Baron.

It stems from a personal connection to the restaurant his father opened a Burger Baron in High Prairie, Alta., in 1987 and his observation that every single Burger Baron was owned by a Lebanese family just like his own.

The documentary debutedon CBC Gem on Sept. 17.

It will be shown on CBC-TVin Alberta and B.C.at 7 p.m. on Sept. 18.

In trackingthe history of the chain, the documentary looks at the demise of the original Burger Baronin the 1950s, which led to its intellectual property becoming a free-for-all. "No one was really interested in it except for this, like, wave of Lebanese immigrants," Mouallem said.

Many of the owners of the restaurants had come to Canada fleeing the Lebanese civil war that raged from 1975 to 1990.

"Three people, you know, cried during our interviews," he said, describing how documentary led him to a deeper story than what he'd been expecting.

"That is not something that I was anticipating for a movie about barons and mushroom burgers."

This isn't the first time Mouallem has written about Burger Baron restaurants. In 2013, he set out on a quest to find the creator of the original Burger Baron chain, and instead found a fraud.

This time however, he is sure he has got it right in an interview withthe son of the man who opened the first Burger Baron restaurant.

"He started off very, very bitter about how his dad's legacy had been kind of culturally appropriated, misappropriated by Lebanese," Mouallem said.

"By the end of the interview, once he realized how his dad's restaurant had actually changed so many lives for the good, he really turned around."
