n. — Food
a jam-filled doughnut.
COD-1 and -2 both label Burlington bun as from Nova Scotia, with unknown origins. This term does not appear in any other dictionaries, and most newspaper quotations directly reference the Canadian Oxford Dictionary. In Canadian web domains, the term does not appear at all (see Chart 1), which suggests that the term is not widely used in Nova Scotia or elsewhere.
See COD-2, s.v. "Burlington bun", which is marked "Cdn (NS)". COD-2's assessment is not matched in our data.
