Good Time reaches the #1 position in Canada, giving Carly Rae Jepsen her second #1 single in her home country. Additionally, she is the first Canadian artist to have two #1s on the chart since 2007 (when the chart began).
What chart did Canada use before they had their Hot 100?
It was run by some other website called Jam Canoe. Around 2006-2007 that chart stopped publishing new charts and Billboard took over. That's why its kinda hard to find information on songs that were released between 2006 and 2007.
