FR-CA meaning in Regional ?

Canadian French (French: français canadien) is the French language as it is spoken in Canada. It includes multiple varieties, the most prominent being Québécois (Quebec French). Formerly Canadian French referred solely to Quebec French and the closely related varieties of Ontario (Franco-Ontarian) and Western Canada—in contrast with Acadian French, which is spoken by Acadians in New Brunswick (including the Chiac dialect) and some areas of Nova Scotia (including the dialect St. Marys Bay French). PEI and Newfoundland & Labrador have Newfoundland French.

In 2011, the total number of native French speakers in Canada was around 7.3 million (22% of the entire population), while another 2 million spoke it as a second language. At the federal level, it has official status alongside Canadian English. At the provincial level, French is the sole official language of Quebec as well as one of two official languages of New Brunswick and jointly official (derived from its federal legal status) in Nunavut, Yukon and the Northwest Territories. Government services are offered in French at select localities in Manitoba, Ontario (through the French Language Services Act) and, to a lesser extent, elsewhere in the country, depending largely on the proximity to Quebec and/or French Canadian influence on any given region. In New Brunswick, all government services must be available in both official languages.

New England French (a dialect spoken in northern New England) is essentially a variety of Canadian French and exhibits no particular differences from the Canadian dialects, unlike Louisiana French and Louisiana Creole.
