RPM was a Canadian music magazine that published the best-performing singles chart in Canada from 1964 to 2000. In 1979, twenty-eight singles reached number one in Canada. The first number one single was from Canadian singer-songwriter Gino Vannelli, with "I Just Wanna Stop" which reached number one in December 1978, and the last was "Babe" from American rock band Styx. Twelve acts achieved their first number-one song in the chart in 1979: the Village People, Amii Stewart, Blondie, Peaches & Herb, Supertramp, Sister Sledge, Anita Ward, The Knack, Patrick Hernandez, Robert Palmer, M and Styx; the Village People and The Knack would also score another number-one hit that year.
