From January 2007 to May 2007, the number-one singles in Canada were compiled by the American-based music sales tracking company, Nielsen SoundScan. The chart was compiled every Wednesday, and was published by Jam! Canoe on Thursdays.[1] On March 31, 2007, Billboard magazine created the Canadian Hot 100, a chart specifically designed for Canada and the first Hot 100 chart that Billboard created for a country outside the United States. The chart was made available for the first time via Billboard online services on June 7, 2007, and it served as the successor to the Canadian Digital Song Sales Chart.
