This paper discusses issues of language revitalization and linguistic prescriptivism related to the teaching of American Sign Language (ASL) in Canada. I describe the current and historical context for ASL teaching, including the increase in ASL course offerings at some postsecondary institutions, and discuss findings related to challenges in curriculum development and issues of prescriptivism as they recur in my study of developing an ASL curriculum for parents of deaf children that is aligned with the "Common European Framework of Reference for Languages."
