In 1976, she joined then-unknowns John Candy, Dave Thomas, Eugene Levy, Catherine O'Hara, Harold Ramis and Joe Flaherty on the Canadian sketch comedy television series, "SCTV", which was set at fictional television station "Second City Television", or SCTV, in Melonville. Martin most notably portrayed leopard-print-wearing station manager Edith Prickley, whose dealings with the staff, including president/owner Guy Caballero, clueless newscaster Earl Camembert, and washed-up actor Johnny LaRue, helped to provide much of the show's humor. Other notable characters Martin played included incomprehensible European immigrant Pirini Scleroso, organ saleswoman Edna Boil, feminist TV show host Libby Wolfson, and children's entertainer Mrs. Falbo. Her talent for impersonation was key in her humorous portrayals of Barbra Streisand, Ethel Merman, Arlene Francis, Pauline Kael, Sally Field, Sophia Loren, Beverly Sills, Lynn Redgrave, Linda Lavin, Bernadette Peters, Liza Minnelli, Connie Francis, Mother Teresa, Joni Mitchell, Alice B. Toklas, Patti Smith, Brenda Vaccaro and Indira Gandhi. In 1981, Martin was Emmy-nominated for Outstanding Supporting Actress in a Variety Show for her work in "SCTV".
