List of number-one singles of 1998 (Canada)

This is a list of music singles that reached number one on the Canadian Singles Chart during 1998. The chart was compiled and published by RPM Magazine until November 16, 1998, after which the responsibility was taken over by Jam! Canoe. Each week, the song most frequently played on Canadian radio stations was declared the number one single.

The year featured a mix of pop, rock, and R&B tracks dominating the charts. Key artists who held the top spot included those achieving their first Canadian number-one single as well as established acts with a continued presence on the chart. These number-one singles reflected the popular music trends and tastes of the Canadian listening audience during that year. Further detail, including exact dates and artists, would need to be sought from archived RPM Magazine and Jam! Canoe charts to compile a complete and accurate listing.
