When researching a variety of Norwegian spoken by some people in the Midwest known as “norst” or American Norwegian, someone commented that it was like the Quebecois of Norwegian.
My native language is English and I am American though, so I guess my own dialect of English would be the Quebecois of my language, or Canadian English too.
In the UK, Scots is close enough to English to be almost comprehensible to an otherwise unprepared British English speaker. (Case in point: Trainspotting.)
