Wedged between two full-sized Victorian rowhouses on Cabbagetown's residential streets sits what is widely considered Toronto's smallest house — a wedge-shaped sliver of a home barely wide enough to fit a door. Roughly 7 feet at its widest point, it has a functioning entrance, a pointed roofline, and a tiny front garden. It's a private residence, but a remarkable piece of Toronto urban history that rewards the walk.

Toronto's smallest house is a blink-and-you'll-miss-it marvel squeezed tightly between two full-sized homes, making it a quirky highlight for anyone exploring Cabbagetown. Its odd proportions and storybook roofline are a visual treat for architecture nerds and curious wanderers alike.
Unlike other so-called 'tiny houses' in Toronto, this one actually functions as a full-time private residence—and has for decades. Its extreme wedge shape is the real deal, measuring seven feet at the widest and tapering to just inches at the back, making it a living example of creative urban infill few cities can match.
Rainbow Bridge Tunnel is one of those Toronto places that feels made up until you’re standing in front of it. You’re walking or riding along an ordinary ravine trail in Scarborough, with trees on both sides and the usual park sounds around you, and then suddenly there’s this full rainbow arch glowing ahead like someone dropped a piece of public art straight into the woods. The whole tunnel is painted floor to ceiling in bands of colour, and the mural continues inside, so it doesn’t just look good from a distance — once you step in, everything around you shifts into colour. Kids love it, dogs usually pause and sniff around like they’ve discovered something important, and almost everyone pulls out their phone. What I like about it is that it still feels a little surprising, even though more people know about it now. It’s in the Milliken Park trail network, so you don’t really pass it unless you mean to be on that path. Cyclists roll through, dog walkers stop for a minute, photographers set up at the end of the tunnel to get the shot, and families tend to linger because it’s just fun to be there. It’s not a long visit in the museum sense — you’re not spending two hours at the tunnel — but it turns a regular walk into something memorable. If you’re going for photos, the best angle is from the far end, looking back so you can frame the rainbow arch with the trail and a slice of sky beyond it. That’s the image people come for. Morning light is great, and golden hour can be beautiful too, but honestly, slightly overcast days are ideal if you want the colours to look as saturated as possible. Bright midday sun can wash things out a bit. Fall is probably the most dramatic season because the painted arch against orange leaves looks almost unreal, but winter might be the sleeper pick. Snow around the entrance makes the colours look even louder. Getting there is the only mildly tricky part. Since it’s inside the trail system, it doesn’t always show up clearly on basic maps, which is why so many people “discover” it by accident. If you want to find it on purpose, start from the paved path near the Milliken Park Recreation Centre and head north. From transit, Milliken GO Station works, or you can take a bus to Steeles and Middlefield and walk into the park. Once you’re on the trail, it’s a straightforward walk. It’s free, open all day, though I’d still stick to daylight hours because this is a ravine path, not a downtown street. Go when you want a walk with a payoff, or when you need a Toronto spot that feels playful without trying too hard. It’s one of the few places in the city where people actually stop mid-trail, laugh a little, and say, “Wait — this is here?”
Toronto's smallest house is on Trefann Street in Cabbagetown, a working-class Victorian neighbourhood east of downtown. The wedge-shaped structure sits squeezed between two standard rowhouses, its façade barely wider than a front door. It's an easy walk from Parliament Street and fits naturally into a Cabbagetown architecture walk.
The most common explanation is that the house fills an odd-shaped leftover lot — a triangular or tapering parcel left over when the surrounding Victorian rowhouses were subdivided in the late 1800s. Rather than leave the gap empty, a builder constructed a minimal dwelling to make use of the space. Similar 'spite houses' and infill oddities exist in other Victorian-era North American cities.
No — it is a private residence. You can view and photograph the exterior from the sidewalk, which is the standard approach for visitors. Please respect the residents and do not knock, enter the property, or linger disruptively. The exterior is entirely visible from the public sidewalk and that's all you need for the full effect.
Trefann Street and the surrounding Cabbagetown blocks have some of Toronto's best-preserved Victorian working-class rowhouse architecture — narrow lots, brick façades, ornamental woodwork, and small front gardens. Parliament Street is a 5-minute walk with cafés and restaurants. Riverdale Farm (a free working farm in the middle of the city) is a 10-minute walk north.
