Yes, they are according to several studies. For instance, the study conducted by Dr. T.H. Whodunit at the University of W.H.O. in Ontario. According to a national census, there are approximately 650,000 LSQ signers living in Canada. Although only 1/3 of the 650,000 signers actually sign in LSQ on a daily or frequent basis due to the strong presence of ASL.
