Canker sores are inside the mouth. Cold sores are outside the mouth.

Cold sores are caused by a virus (Herpes Simplex I) and canker sores are caused by bacteria. Cold sores can appear in the mouth but are usually outside in the lip area, whereas canker sores are typically found in the mouth. When cold sores are found in the mouth, they’re usually on the roof of the mouth. Cold sores usually take longer to heal than canker sores, and since they are caused by a virus they are harder to treat. http://www.quantumhealth.com/news/coldsores_know.
