Multiplexes in Old Toronto

Old Toronto is the pre-amalgamation core — the Annex, Leslieville, Riverdale, the Junction, High Park, Parkdale, Trinity-Bellwoods. It was built before the car, on narrow deep lots that back onto a public laneway grid, with the best subway and streetcar access in the city. That makes it the strongest area in Toronto for laneway suites and for converting Victorian and Edwardian semis into multiplexes. It also holds most of the wards where sixplexes are now permitted. Pull the hard numbers for any neighbourhood from the City's Neighbourhood Profiles.

Key Takeaways

✓Deep lots backing onto a public laneway grid — the strongest area for laneway suites.
✓Four units as-of-right in any residential Neighbourhoods zone; up to six in the sixplex wards here.
✓Most of the nine sixplex wards — including Parkdale–High Park, Davenport, Toronto–Danforth — sit in Old Toronto.
✓Victorian and Edwardian semis convert to a fourplex inside roughly the existing house envelope.

Why Old Toronto Fits Multiplex Infill

Deep lots backing onto laneways

The pre-amalgamation core was platted before the car. Its narrow, deep lots back onto a public laneway grid that runs behind the houses — the exact condition a laneway suite needs. That makes Old Toronto the strongest area in the city for stacking a laneway suite behind a multiplex.

The best transit in the city

The Annex, Trinity-Bellwoods, Leslieville, and Riverdale sit on subway and streetcar lines that predate the suburbs. Walkability and transit access are what made parking minimums removable here first, which lowers what a multiplex needs to fit on the lot.

Most of the sixplex wards

When the City extended permissions to six units in June 2025, it did so in nine wards — and most of the Toronto and East York district wards sit inside Old Toronto. Parkdale–High Park (Ward 4), Davenport (Ward 9), Toronto–Danforth (Ward 14) and others let a lot here go beyond the four-unit city-wide ceiling.

Best For

✓ Deep laneway-abutting lots where a laneway suite stacks behind a fourplex conversion.
✓ Lots in the Old Toronto sixplex wards (e.g. Parkdale–High Park, Toronto–Danforth) aiming for six units.
✓ Victorian and Edwardian semis that convert inside the existing building envelope.

Usually Fails When

✕ A sixplex is assumed on an Old Toronto lot whose ward is not one of the nine.
✕ A Heritage Conservation District is overlooked — many Old Toronto blocks carry one.
✕ A laneway suite is planned on a lot that does not actually abut a public lane.

What To Verify Before Spending Money

→ The residential zone and Neighbourhoods designation for the parcel.
→ Which ward the lot is in, and its sixplex status.
→ Whether the lot abuts a public laneway and any heritage designation.

Frequently Asked Questions

Is Old Toronto a good place to build a multiplex? +

For missing-middle infill it is the strongest area in the city. The pre-amalgamation core has narrow, deep lots backing onto a public laneway grid, the best subway and streetcar access in Toronto, and it contains most of the nine wards where sixplexes are now permitted. Up to four units are permitted as-of-right anywhere in a residential Neighbourhoods zone; in the Old Toronto sixplex wards, up to six. Confirm the specific lot against the City's Neighbourhood Profiles before planning.

Why is Old Toronto the best fit for laneway suites? +

A laneway suite is permitted only on a lot that abuts a public laneway. Old Toronto's streetcar-era grid was built with rear laneways running behind the houses, so a large share of its lots qualify — far more than the postwar suburbs, which were rarely platted with lanes. That lets an owner add a laneway suite behind a fourplex conversion.

Can I build a sixplex in Old Toronto? +

In several of its wards, yes. The June 2025 sixplex permissions cover nine wards, and most of the Toronto and East York district wards — Parkdale–High Park, Davenport, Spadina–Fort York, University–Rosedale, Toronto–St. Paul's, Toronto Centre, and Toronto–Danforth — fall inside Old Toronto. A lot in those wards can go to six units; a lot in a ward outside the nine is capped at four unless the ward opts in.

Which Old Toronto neighbourhoods suit a fourplex conversion? +

The Annex, Leslieville, Riverdale, the Junction, High Park, Parkdale, and Trinity-Bellwoods all carry Victorian and Edwardian semis on deep lots — stock that converts to three or four units inside roughly the same building envelope as the existing house. Each neighbourhood has its own lot pattern and heritage status, so check the City's Neighbourhood Profile for the area before you commit.
