"Gopher It" was the 19th and final episode of the fourth season of Corner Gas, and the 69th in its history. It first aired on CTV on March 12, 2007. Some promotion for the show, particularly a TV spot set to Blue Rodeo's 1994 hit, "Bad Timing," as well as a press release from CTV, had some fans wondering if the series was coming to an unexpected end. The matter was soon cleared up by CTV. Just past the midway point of the episode, Canadian Prime Minister Stephen Harper makes a cameo appearance, just as his predecessor, Paul Martin, did in Season Three's "Fun Run."
