As with the first season, fifty homecooks are given the opportunity to cook and present their signature dishes for Michael Bonacini, Alvin Leung and Claudio Aprile; an auditioning cook requires at least two "yes" votes in order to obtain a MasterChef Canada apron and advance to the next round. The episode features the auditions of Sabrina, Jon, Kristal, Michael, Tammy, Jennifer and David; all except Kristal are able to earn an apron and move on to the next stage of competition.

After the last of the Top 50 homecooks finish their auditions, including Line and Debbie who round out the Top 25, the apron-winning homecooks were brought into the MasterChef Canada kitchen for a challenge to determine the Top 16. Sixteen were told to take a spot in the kitchen; the other nine - Christopher, David, Debbie, Debra, Jennifer, Kevin, Kristen, Kwasi and Tammy - automatically advanced as their signature dishes were deemed the best of the auditions. The remaining sixteen cooks were given 60 minutes to prepare a dish inspired by the red-and-white Canadian flag-shaped pantry behind them. Two groups were initially called forward after the cook; the former, consisting of Andrew, Cody, Kyle and Sabrina, advance to the Top 16, while the other group, including Gav, Nikita, Robert, Nathan and Mina were sent home. The remaining six cooks' dishes were given a closer look: Inder and Deanna were eliminated while Line and Michael advanced, leaving Lauren and Jon to fight for the last spot. Jon's dish was narrowly deemed the better of the two, and Lauren was eliminated.
