I recall a study years ago which found that Canadians followed by Singaporeans spoke English close to a neutral accent.
The "true blue" (Caucasians, mostly Anglo) Canadians speak with a neutral accent, but usually end with an "eh"
However, not all of the other newer immigrants speak with a neutral accent.
Most of the bilingual (as in the Official Languages, of English and French) Canadians are Francophones.
But there are numerous Canadians who speak 2 or more languages, because they usually go to Saturday schools to learn their mother tongue.
Our children also attend Saturday school from 0900 to 1300 hours, to learn the language of their mother (my spouse).
Unfortunately, to try to enrol them to learn Mandarin, may be a little too much, as they will not have much recreation or free time on the weekends.
