The Canadian Hot 100 is a music industry record chart in Canada for singles, published weekly by "Billboard" magazine. The Canadian Hot 100 was launched on the issue dated June 16, 2007, and is currently the standard record chart in Canada; a new chart is compiled and officially released to the public by "Billboard" on Tuesdays. 

The chart is similar to "Billboard"s US-based Hot 100 in that it combines physical and digital sales as measured by Nielsen SoundScan, streaming activity data provided by online music sources, and radio airplay as measured by Nielsen BDS. Canada's airplay chart is the result of monitoring more than 100 stations representing rock, country, adult contemporary and Top 40 genres. 

The first number-one song of the Canadian Hot 100 was "Umbrella" by Rihanna featuring Jay-Z on June 16, 2007. As of the issue for the week ending October 7, 2017, the Canadian Hot 100 has had 117 different number-one hits. The current number-one is "Rockstar" by Post Malone featuring 21 Savage. 

The chart was made available for the first time via "Billboard" online services on June 7, 2007 (issue dated June 16, 2007). With this launch, it marked the first time that "Billboard" created a Hot 100 chart for a country outside the United States. "Billboard" charts manager Geoff Mayfield announced the premiere of the chart, explaining "the new "Billboard" Canadian Hot 100 will serve as the definitive measure of Canada's most popular songs, continuing our magazine's longstanding tradition of using the most comprehensive resources available to provide the world's most authoritative music charts." The "Billboard" Canadian Hot 100 is managed by Paul Tuch, director of Canadian operations for Nielsen BDS, in consultation with Silvio Pietroluongo, "Billboard"s associate director of charts and manager of the "Billboard" Hot 100.
