A socially stratified sample—the Toronto English Corpus—together with the construct of apparent time (with speakers aged 10–90 years) reveal that certain features are declining, including future will, deontic have got to, possessive have got, intensifier very, and the sentence tag you know. On the other hand, some features are on the rise, including future going to, deontic have to, possessive have, intensifiers really and so, and sentences tags such as whatever, so, and stuff like that. The younger generation is pushing these changes forward more rapidly. While some developments date back hundreds of years in the history of English, they are not particular to Canada, and are consistent with research on other English corpora. Other changes appear to be progressing in a unique way in Canada, including deontic and possessive have. I argue that the broader socio-historical context is a critical factor: geographic and economic mobility as well as changes in communication technology may explain the rapid acceleration of certain types of linguistic change.
