New Edinburgh is an affluent neighbourhood on the east side of the Rideau River, founded by Thomas McKay, a Scottish stonemason and entrepreneur who was involved in the building of the Rideau Canal. He bought a great deal of land here and created a village in the name of his native Edinburgh. It is home to a number of embassies, ambassadorial residences, Rideau Hall, and the lair of the Dark Lord (otherwise known as 24 Sussex Drive), where the Prime Minister lives.
This old schoolhouse dates back to 1837. Today it's home to offices. The place is also very close to an embassy I'll show you tomorrow.
A short walk up the street is a plaque in McKay's name.
