The eatery partnered up with 'plant-based pioneers' Lightlife to create a meatless chicken burger and popcorn chicken - which were available for one day on November 27.
The Plant-Based Fried Chicken sandwich (available in regular or spicy) was priced at $6.99 or in a meal starting from $8.99, while the Plant-Based Fried Popcorn Chicken bucket retailed at $3.99.
"And just like that, we're all sold out! Stay tuned for more chances to try our Plant-Based Fried Chicken at KFC Canada," Lightlife wrote on Instagram.
While KFC Canada added: "That was finger-lickin' good while it lasted. Our Plant-Based Fried Chicken by Lightlife Foods is sold out, but stay tuned for its return."
Earlier this year, KFC trialed vegan nuggets and boneless wings made by plant-based company Beyond Meat at a store in Smyrna, Atlanta (USA).
Reports claim the outlet sold the same amount of vegan chicken in the five hours, as it usually sells of animal-based popcorn chicken in a week.
Tweeting about the sales, KFC said: "All of the Colonel's Beyond Meat Kentucky Fried Chicken has sold out. Yes, it is truly a Kentucky Fried Miracle."
