h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

London on the Thames was purposly named after the real London on the Thames as it was going to be the capital of Upper Canada at its founding.

I've never heard of "Washington" Ontario.

That fountain was never built because people didn't support it wholeheartedly...
why would anyone want a fountain spurting polluted Thames water up in the air?

My registration to this site was inspired this posting under North America -> Canada -> Ontario -> London Ontario. In a post in this section, it is stated that "I've never heard of "Washington" Ontario."

It struck me - who has? There is indeed such a place. If on the 401, simply exit at what was formerly known as Highway 97 (Just west of Kitchener, Ontario). Follow this highway west, and you will eventually go through Washington, Ontario. Now, be sure to observe the posted reduction to the speed limit as you travel through here. I advise this not as I think the local law enforcement officials are laying in wait for speeders, but rather if you don't, you will blink and miss Washington all together (If you see a sign advising you've arrived in Plattsville, stop, turn around and try again (set the cruise control this time, and pay attention!))

Having driven through there several times, I must admit however, I have absolutely no idea what really constitutes Washington. 4 houses and a garage I think. Maye one of the houses is even white.

That water fountain has been built, it's between the Peace Park and Dundas Street at The Forks.
Not very impressive, mind you, and extremely easy to miss (even by Washington's standards).
