Corner Gas is filmed in the small town of Rouleau, Saskatchewan, near Regina. The town of Rouleau allowed numerous changes for the show, including the painting of "DOG RIVER" on the town's grain elevator. However, the town refused to allow their water tower to be repainted. The tower says Rouleau, and thus is never seen on the show, despite the episode "Grad '68" heavily featuring the water tower. The inside scenes (Ruby Cafe interior, Police Department, Oscar and Emma's house, etc.) are filmed at Canada/Saskatchewan Production Studios in Regina.
