Commentators and spokespersonsEdit
CTV broadcasted the Retro WWW Song Contest from the 23rd contest up until the 31st and averaged 1.95 million viewers during its broadcasts. After Canada was relegated from the 32nd, and a continued decrease in ratings, CTV announced that the broadcast would move to CTV Two. However, the broadcaster stated that in the event of a victory, the broadcast would return to the main CTV channel.

CTV Two negotiated with Céline Dion in hopes for her return, which was success. Despite Dion's participation, the broadcast only managed to score 1.76 million viewers, 1.20 million less than Dion's participation in the second edition. As a result, a big search was made for Canada's tenth participation, which ended in Canadian pop-rock singer Amanda Marshall representing the nation. Previous winner Avril Lavigne was also appointed as the voting spokesperson, showing the broadcaster's dedication. The contest saw a decrease of viewers with 1.62 million viewers watching the contest. Once again, the contest saw a decrease for the eleventh edition with only 1.49 million viewers tuning in. CTV Two announced that for the 12th participation, a "dance hit" would represent the nation.
The 37th contest saw Canada achieve second place, the nation's highest placing in nine editions. This is also resulted in a 2.26 million viewership; the highest in six editions. However, CTV stated that reaching two million viewers could just be an one-edition special, and that "if this number were to surpassed in the following edition, the contest would return to CTV."
It was shortly announced that Lara Fabian would join Rick Mercer to commentate the 37th edition, a move which was considered a guarantee for a CTV-switch. Hours later, it was also confirmed that both Mercer and Fabian would present the Canadian points as the spokespeople. With famous Canadian singer-songwriter Shania Twain representing the nation, the buzz was reported to be "the highest" since Céline Dion representing Canada in its 24 debut. Due to the buzz, CTV announced that both CTV and CTV Two would broadcast the contest simultaneously, and that should the ratings pass the 2.26 million mark, the contest would permanently return to CTV.
