To help understand the diversity of Canadian mathematics education, our contribution relates to the English Canadian reality, having completed separate papers on the Quebec and New Brunswick contexts. As a country that is officially « bilingual » (English/French), Canada has unique constitutional considerations within education: each region must provide minority populations with both primary and secondary level education in their own language (English in Quebec, French elsewhere), yet education remains the sole responsibility of the individual provinces and territories, as there is no national education body or standardized, national curriculum. Whereas the province of Quebec is officially considered « unilingual » (French), and New Brunswick considered « bilingual » (English/French), the rest of the Canadian provinces/territories are made up of English and French minorities (i.e., anglophones / francophones) with education offered in both languages depending on population, as well as « Immersion » language programs in some jurisdictions.
