Most of the National Capital Region is recognized as a bilingual region for federal language-of-work purposes.
In addition, the City of Ottawa has a Bilingualism Policy, but is not declared "officially bilingual" (which would require amendments to the provincial law). About 19% of the population of the City of Ottawa has French as their first language, while 40% of the total population of the city declares itself fluent in both languages.
The National Capital Region includes the English-speaking (Ottawa) and French-speaking (Gatineau) cores. The metro region has a bilingual population of 496,025, an English-only population of 507,175, and a French-only population of 102,375.Ottawa-Gatineau CMA
