This month’s issue of Canadian Megatrends, “The evolution of language populations in Canada, by mother tongue, from 1901 to 2016,” examines the makeup of the country’s population by mother tongue, which has undergone significant change since 1901. In the early 1900s, nearly 90% of the Canadian population spoke either French or English as their mother tongue. The remainder had either an Aboriginal or immigrant language as their mother tongue.
