Waste not, want not! In this high-stakes QuickFire challenge, a hot-button culinary issue is put to the test when the chefs are challenged to produce a Top Chef Canada quality dish while creating as little food waste as possible. Judged by James Beard award-winning chef Danny Bowien, the winning chef earns a special immunity that holds more power than ever seen before. Canadian culinary icon Lynn Crawford judges the ultimate farm-to-table Elimination Challenge where the chefs must feed the farmers, creating dishes that highlight Canadian vegetable, fruit, grain, dairy and egg farms.

In a QuickFire Challenge that tests vision and leadership, the chefs are paired with culinary students to teach them a dish...but are thrown one major curveball. With 16 cooks in the kitchen, mass chaos ensues. Later, the chefs are divided into two teams to conceptualize and create the ultimate menu in the marquee Elimination Challenge of the season, Restaurant Wars! The stakes are higher than ever as a massive twist threatens to alter the competition. Superstar food writer and critic, known for making and breaking restaurants, Ruth Reichl joins as guest judge.
