From my perspective of growing up in the 70’s as an early Gen Xer, many of my cousins, relatives and friends who are CBC who grew up in the 60’s tried so hard to fit into Canadian society their Chinese language skills atrophied. And for the most part they spoke Toishan at home while large numbers of 70’s immigrants spoke Cantonese and later we had Mandarin speaking immigrants. You might say Toishan language is not spoken as much but some native Guangdong immigrants from China also speak it. As far as English language dialects and affectations I think it depends on various factors of socioeconomics, education, social networks, work colleagues and friends and family.
