Frequently Asked Questions

What are the most unusual buildings in Toronto?

Toronto's most unusual buildings include 54½ St. Patrick Street (the Half House — a Victorian row house only 4.5 metres wide that survived road widening demolition), the Gooderham Flatiron Building (a 1892 wedge-shaped office building at Front & Church), the OCAD University campus (a pixelated black-and-white box floating on stilts above Grange Park), Old City Hall's carved grotesque faces (Victorian gargoyles most people look up past), and the Oculus Pavilion in Grange Park (a 1970s flying-saucer concrete canopy).

What is the Half House in Toronto?

54½ St. Patrick Street is one of Toronto's most famous architectural oddities — a Victorian row house that was left standing when its neighbour buildings were demolished for road widening, resulting in a structure approximately 4.5 metres wide. It is a private home, viewable from the public sidewalk only. Located near Dundas and University Avenue, it's a 5-minute walk from Osgoode subway station.

What is The Grange in Toronto?

The Grange is Ontario's oldest surviving brick house, built around 1817 for D'Arcy Boulton Jr. of the Family Compact (the ruling elite of early Upper Canada). It sits directly behind the Art Gallery of Ontario (AGO) and is now part of the AGO's building complex. The house is a Georgian brick mansion that has been remarkably preserved amid the urban development around it. Access is through the AGO.

What is the walking route for Toronto's weird buildings?

The best weird buildings walk runs through the Queen West / AGO / Chinatown loop: Start at Osgoode Station → walk north on St. Patrick Street to see the Half House (54½) → west to Grange Park and the Oculus Pavilion → AGO and The Grange → south on McCaul → east on Queen W to the Gooderham Flatiron (via King to Front) → north to Old City Hall grotesques on Queen E. Approximately 3km, 1.5–2 hours.
