I suppose that you really have to come up with something shorter to fit on road signs when the full name of your municipality is the United Townships of Dysart, Dudley, Harcourt, Guilford, Harburn, Bruton, Havelock, Eyre and Clyde. The initialism of UTDDHGHBHEC doesn’t look much better and isn’t very catchy. But you’d think that since the initial amalgamation of the first four of these in Haliburton County in 1867, the township et al’s residents would have been able to let some of the names slip into history.
On the other hand, living in Toronto et al, formed in 1954 with a full name of the United City of Toronto, Scarborough, East York, Leaside, North York, Forest Hill, York, Weston, Swansea, New Toronto, Mimico, and Long Branch would have its charms.
