Tier 1

After the competitor receives their number at the registration desk, they are allowed to go to other places until their number is called. After their number is called, they will be asked to wait in the front line for their audition for the first round. Auditioners will be sent in groups of five, taken to the waiting room by an audition crew. The audition crews responsible for the groups will take the competitors to Tier 1, where they will audition to the representative of a producer with their group.

Each auditioner will take turn to sing one song for as long as they want. If the representative is not sure about the competitor's performance, they may ask them to sing another song. After all five auditioners have sung, the representatives may make comments, and announces auditioners that will not go through to the second round. The successful auditioners will be given a Yellow Ticket, and will return to the waiting room to wait for an audition crew to lead them to a separate waiting room where they wait for the second round of audition.

Tier 2

After the auditioner's number is called for the second round of audition known as Tier 2, an audition crew will take them along with couple others to the waiting room once more. The competitors will have to wait there until their number is called, and then they will be sent into the audition room. In Tier 2, the competitors will audition to a producer of the show, where they will be asked to sing a minimum of two songs. The successful auditioner will receive a Blue Ticket, and will need to return to the registration desk to register for the Celebrity Judges round.

Celebrity judges

By assigned order of time on successful auditioner's registration paper, they will be called into the final round of audition where they meet the Canadian Idol Celebrity Judges Farley Flex, Jake Gold, Sass Jordan and Zack Werner. It will be held at a secret location on another day.

In this round, the auditioner will have to prepare one song in the song list that is given to you when you are registering for the third round, along with four other songs of your own choice. Successful auditioners will be given a Gold Ticket, where they will have a chance to participate in the Top 200 week in Toronto.

The Gold Ticket receivers are asked to remain absolutely silent, or they may face possible disqualification due to fairness purposes.
