The Foo Mart was Dog River’s grocery store. When the producers of the show arrived in Rouleau, they found the sign in the basement of the building, but it was missing letters. They thought that was funny and kept the sign the way it was. As part of Dog River’s quaintification in Corner Gas: The Movie, the sign was filled in to read FOOD MART, but it never really looked right!
Unfortunately, the building was destroyed by a fire in September 2014.
