In Canada, having fluency in English and French is mandatory (In some important government jobs like prime minister). This is considering that the group of French people in Canada is just about 20% of the population and a report says that-
In the 2011 Census, 5.8 million people nationwide reported being able to conduct a conversation in both English and French, which corresponds to a bilingualism rate of 17.5%.
And the majority of bilingual people are from the single French-speaking province, Quebec, where 42% of the population is bilingual. And part of the aforementioned report is that-
Between 2001 and 2011, the lack of growth in bilingualism outside Quebec occurred as the non‑Francophone immigrant population was growing and the proportion of students in French-as-a-second-language (FSL) programs was shrinking.
From both these excerpts it is said that 17.5% or only (roughly) one in five Canadians are eligible for being prime minister or governor-general and the rest 82.5% of the populace is getting more disinterested in learning a secondary French or English language.
Also to mention is the immigrants who come from France and other Francophone nations from Asia (like some parts of Vietnam and India) or Africa also, by the most part speak English. But for immigrants coming from, say India, then they would have to be burdened by learning French to attain those (important and high-profile) government jobs (considering that Indians are also fluent in their native language and English).
