The public read of what [nar_connection()] actually downloaded. A national database reports every province rather than the internal `"ALL"` marker, so the return value can be compared against a `PROV_ABVN` column without special-casing.
Examples
if (FALSE) { # \dontrun{
con <- nar_connection(provinces = "BC")
nar_provinces(con)
#> [1] "BC"
} # }
