15456 Maritime Sign Language 10-99 "Although the majority of Canada's Deaf population currently uses American Sign Language (ASL), some Deaf people continue to use MSL, which is thought to stem from British Sign Language (BSL). ASL is quickly encroaching on MSL and is now the dominant language for Deaf people in the provinces of New Brunswick, Nova Scotia and Prince Edward Island. There are an estimated fewer than 100 MSL users." Canada's Maritime Sign Language On <100 10-99
