In Toulouse, taxis all have GPS because they couldn't work without them. You ask them about places, they don't even try most of the time, they just punch it in, and don't even know where it is. Every street changes names at least once, and on average runs less than 200 metres with any given name. Look up the Avenue de Lardenne there on Google Maps, and follow it in almost a straight line to become Avenue de Lombez, Avenue Etienne Bilières (heh, I didn't even know that part's name, even though I rode my bike down that street every day or so!), Rue de la République, Rue de Metz, Place Esquirol, then Rue de Metz again (it then changes names again, but there's a fork in the road, so I deem it acceptable there, and I shall stop). I explained that the Boulevard René-Levesque here was many kilometres long, and they were amazed at the "great Canadian spaces", but then I pointed out that La Rocade Arc-En-Ciel (name of just one segment) was in fact much bigger and longer, but that they just couldn't bloody stick to one name for it.

My friend claimed it's because they have more history, they have to give the names of their heroes to their streets and places, but they're running out. Heh.

There's also "Chemin Côte-St-Antoine". They're named after hills, but they are not hill streets.

Aylmer was only the stretch between Ste-Catherine and Sherbrooke.

From Sherbrooke to Prince-Arthur, it was Shuter Street,

From Prince-Arthur to Pine, it had yet a different name, which I can never remember.

McGill Street -> Square Victoria -> Beaver Hall Hill -> Place Frère-André -> Place Phillips -> Phillips Square -> Aylmer St?

(South)
Rue McGill
Square Victoria
Côte Du Beaver Hall (I can't think of another time where "Côte" is a street generic)
Place Phillips
Place du Square Phillips (?)
Rue Aylmer

Which, according to Google Maps takes 29 minutes to walk, from 2 Rue Mcgill to 3600 Aylmer.

Rue McGill (Notre-Dame) Square Victoria (Viger) Côte du Beaver-Hall (René-Lévesque) Place du Frère-André (...not applicable?) Place Philips (Ste-Catherine) Rue Aylmer

(The square is called Square Philips, but if you believe the STM, the eastern-side street is called Place Philips. Cf: http://www.stm.info/metro/McGill.pdf)
