Food Network Canada says the celebrity chef will be among 12 acclaimed cooks from around North America vying for $100,000 for a charity of their choice.
The new season of "Top Chef Masters" will debut July 24 at 10 p.m. ET/PT on Food Network Canada.
Each competitor will also be teamed with a sous chef.
Crawford's sous chef is Lora Kirk, who works with her at her Toronto restaurant Ruby Watchco.
They'll battle to win the cash prize for the Odette Cancer Centre at Sunnybrook Health Sciences Centre.
In a new twist this season, each sous chef must also compete in an online competition hosted by Canadian celebrity chef Hugh Acheson.
Every episode of "Battle of the Sous Chefs" will lead up to — and have a direct impact on — the next on-air instalment of "Top Chef Masters."
Fans can get a sneak peek at "Battle of the Sous Chefs" when the first episode is posted on foodnetwork.ca beginning Thursday.
Crawford, former executive chef of the Four Seasons Hotel in Toronto and New York City, has competed on "Iron Chef America" and starred in the series "Pitchin' In."
She also owns the food shop Ruby Eats and is set to publish her second cookbook in September.
Celebrity chef Curtis Stone returns as host of "Top Chef Masters" alongside new head critic, Toronto-bred Gail Simmons.
Returning judges James Oseland, Ruth Reichl and Francis Lam will be joined by new judge, food and dining editor Lesley Suter.
Celebrity guest judges this season will include Mindy Kaling, Busy Philipps, Kathie Lee Gifford and the cast of "Days of Our Lives."
