Yes, it is. The process by which heat changes the molecules of the bread from white and soft to brown and crispy is a chemical change. A chemical change does NOT mean you have to add chemicals. It just means the chemicals (molecules) in the substance changed their chemistry. So slicing bread is a physical change, but toasting it is a chemical change.
