In 1930, he began performing on Calgary radio and gained popularity for his easygoing vocal style, heartfelt lyrics, and yodeling technique. His first recording session in 1933 for RCA Victor produced the hit “My Swiss Moonlight Lullaby,” which became a signature song and launched his recording career in both Canada and the U.S. He moved to the U.S. during the 1930s and was marketed as Montana Slim — a cowboy troubadour appealing to both Canadian and American audiences. Throughout the 1940s–1960s, he hosted his own radio shows, made numerous recordings, and performed live across North America, becoming one of the most prolific Canadian recording artists of his time. Over his lifetime, he released hundreds of songs across more than 40 albums.
Carter’s music blended folk storytelling, frontier romanticism, and yodeling into a uniquely Canadian form of cowboy balladry.
His songs often evoked the western landscape and rural life, love, home, and travel, and the working cowboy’s hardships and humor. Musically, he helped define the “Canadian country” sound — a gentler, narrative-driven cousin to the rougher American honky-tonk style.
Carter’s long career, spanning more than six decades, laid the foundation for Canadian country artists such as Hank Snow, Stompin’ Tom Connors, Ian Tyson, and Shania Twain. He was inducted into the Canadian Country Music Hall of Fame in 1984 and remains revered as “The Father of Canadian Country Music.” His influence also extended to broadcasting: his radio programs and early recordings helped establish a Canadian market for country and western music during a period when American acts dominated.
Notable Songs are My Swiss Moonlight Lullaby (1933), There’s a Love Knot in My Lariat, The Capture of Albert Johnson, Blue Canadian Rockies, I'm Gonna Ride to Heaven on a Streamlined Train, and Rattlin’ Cannonball.
