Yes it is, as the browning of the bread when you toast it, is a reaction between the reducing sugar and amino acids. The reaction is called Maillard reaction.
In simpler words, the bread is being "burned" which is a chemical change as it cannot be reversed. You can't get back the same soft,fluffy, white bread after you toast it.
