Drain the canned chicken thoroughly and place into a large mixing bowl.
Use two forks to shred the chicken into uniform, bite-sized pieces.
Add the diced celery and red onion to the bowl with the chicken.
In a separate medium bowl, whisk together the Greek yogurt, buffalo hot sauce, garlic powder, onion powder, salt, and black pepper until smooth.
Pour the dressing over the chicken mixture and fold gently until all components are evenly coated.
Cover and refrigerate for at least 30 minutes to allow flavors to develop before serving.
Serve chilled as a wrap, over greens, or with vegetable sticks.
