Statistics Canada has published a document titled Statistics Canada Data Sources on Official-Language Minorities “This document is primarily intended as a reference tool on the different sources of language information available to users of Statistics Canada data. It lists, in addition to the census, the surveys and administrative databases that provide information on official languages. The information provided in this document will facilitate access to Statistics Canada data by informing researchers about the availability of survey data, access to databases and, especially, the various themes that can be explored to contribute to what is known about official-language minorities in Canada.”
