In 1985, RPM magazine published a chart for top-performing singles in the adult contemporary category in Canada. The chart, entitled Adult Contemporary, undergone numerous name changes throughout its existence, becoming Adult Contemporary in August 1984 until the magazine's final publication in November 2000. In 1985, thirty-five individual songs topped the chart, which contained 30 positions and is based on record sales and adult contemporary radio station playlist submissions.
In RPM's first issue for 1985, the first adult contemporary number-one was a cover version of the 1950s hit "Sea of Love" by the short-lived supergroup The Honeydrippers, led by former Led Zeppelin members Robert Plant and Jimmy Page. After two weeks, "Sea of Love" would eventually be knocked off the top by Jermaine Jackson's "Do What You Do", which topped the chart for two weeks. "Do What You Do" would then be dethroned by Jack Wagner's "All I Need", which topped the chart the first week of February. A week later, "Careless Whisper" by Wham! would top the adult contemporary chart for the rest of February 1985, a week after the single topped the Canadian top 40 chart for two consecutive weeks. Wham! would have a second number-one adult contemporary hit with "Everything She Wants", which topped the chart for the week of June 8. Two artists would also have two number-one adult contemporary hits each for 1985, first with Phil Collins, with "One More Night" and "Separate Lives" (a duet with Marilyn Martin, from the White Nights soundtrack), and Stevie Wonder, with "Love Light in Flight" and "Part-Time Lover". Two Canadian acts would have at least one number-one adult contemporary hit for 1985, first with charity supergroup the Northern Lights with the single "Tears Are Not Enough" which topped the chart the week of May 11, followed by Corey Hart with "Never Surrender" the week of July 20. The final number-one on the chart for 1985 was Lionel Richie's "Say You, Say Me", which reached number-one on the final weeks of December.
