This circa-1866 mansion with spectacular seasonal gardens reopened in 2010 after an extensive, expensive renovation. The result is worth a visit: Now a museum run by the City of Toronto, it's a year-round destination to get a sense of domestic life in Toronto in the 1920s and '30s. The garden is also themed: It's a Victorian-Edwardian masterpiece. The Austin family occupied the house from 1866 to 1980, and successive generations modified and added to the house and its decor.

Park Yourself Here -- Spadina House is the next-door neighbor of Casa Loma. Between the two is a small but lovely park that is almost hidden by the trees that shade it. Many visitors don't notice it, but locals love it. Grab a bench here if you want to take a breather.
