Yonge-Dundas Square. College Park. The Eaton Centre. Then the street unfolds in theatres, soaring towers, and fine-grained 20th century retail, before reaching down to the Lake, and stretching past Bloor Street, midtown, uptown, out of town, and into a seemingly endless north. This is Yonge Street, Toronto's most famous thoroughfare, which forms the spine — and perhaps the heart — of the city. But it doesn't look it.
