The Canadian English vowel system is undergoing a shift, and the dialect of English spoken in St John’s, Newfoundland—which for demographic and geographic reasons has remained autonomous from North American varieties—is being affected by this change. Incorporating both real-time and apparent-time data, the findings show a process of communal and generational change. The front lax vowel lowering and/or retraction that characterize Canadian Shift appear to be active in St. John’s English. Consistent with the late adoption model of language change, older speakers show ongoing changes from their early 20s through to middle age. Moreover, the older female cohort seems to lead in the adoption of supralocal Canadian English forms, and this both in apparent time and in real time. This challenges the idea that younger generations are the sole or primary locus of language change. While innovative forms are typically associated with younger speakers, this study shows that they can also be adopted, accelerated, and advanced by older speakers.
