This brings up another name related thing...

Here there is a major road called René Levesque that is called Dorcester by English people over 30.

A town named Lac Moreau by the government and Lac St Paul by it's inhabitants and anyone knowing the place.

And an autoroute called "the 10" by everybody but actually named "Autoroute of the Eastern Cantons"

(oh and our Beaconsfield is actually pronounced Beacon's field :-) )
