Type: 5. Frequency — This meaning of jambuster, which is unrelated to previous meanings, is a Canadian innovation. In the UK and the US, jambuster is used in contexts of new infrastructure designed to reduce traffic congestion, dating back to the 1950s in the case of the latter.
Jambuster 'donut' is used in Manitoba; the term is enregistered as Manitoban (see the 2005 quotation) and is also used in Ontario (see the 1998 quotation). The earliest known newspaper citation is from 1994. Jambuster is most prevalent in Canada according to internet domain searches (see Charts 1 and 2), with the spelling donut being more frequent in this connection in Canada than in the US (see also bismarck, Charts 1 & 2).
