YORK. This living-history village recreates the 1860s with more than 30 restored buildings and such craftsmen as tinsmiths, blacksmiths, millers, clock-makers, and weavers selling their wares. Visitors will also find demonstrations of spinning, hearth cooking, and quilting. Special theme weekends are held as well, and food is available.

MIDTOWN. This stately castle has been dubbed "a rich man's folly." Built in 1917 by Sir Henry Pellat (a financier and military officer) for the exorbitant price of $3.5 million, the home was a gift to his wife. Within ten years, it was valued at only $27,305. It features beautiful, 17th-century architecture, including Elizabethan chimneys, Rhenish turrets, underground tunnels, and secret passageways. The furnishings originally cost $1.5 million. Other features include a marble swimming pool, a 10,000-volume library and 15 baths. Even horses lived in luxury with their names engraved in 18-carat gold above their stalls. Self-guided audio tours (available in seven languages) are available at no additional cost.

DOWNTOWN. These seven historical acres house Canada's largest collection of original buildings dating to the War of 1812. The restored fort is a designated National Historic Site, and many of the original buildings are surprisingly intact. Costumed staff perform frequent period demonstrations, and guided tours are available; both are seasonal, in July and August. Limited wheelchair access. Free parking.

DOWNTOWN. Heritage Toronto offers historic and architectural walking tours during summer months. Popular subjects include Toronto's churches, banks, cemeteries, and neighborhoods, as well as the Distillery Historic District and the University of Toronto.

Call for details.

DOWNTOWN. Operated by the City of Toronto, this gas-lit Victorian structure was once home to the city's first mayor, William Lyon Mackenzie. In the 1930s, local citizens saved the house from demolition, and it was restored and opened as a public attraction in 1950. Today, a gallery addition features changing exhibits, and the costumed staff presents demonstrations of 19th century life. Special programs for children are offered during summer months, and the site is available for private functions.
