Toronto permits a fourplex — four self-contained units — on most residential lots as-of-right, no rezoning required. Here's what's allowed and where to find a lot.

Sample of lots for sale across Toronto.
Across Toronto, most residential lots now allow up to four units (a fourplex) without a rezoning. In the nine Expanding Housing Options in Neighbourhoods (EHON) pilot wards you can go to six units (a sixplex). Many deeper lots can add a garden suite at the rear for one more unit, and lots fronting a designated major street can qualify for a small apartment building well beyond six units.
Use the interactive map to see every lot's as-of-right unit count, lot width and depth, zoning, and whether it's in a sixplex ward or on a major street. There are 2,648 lots for sale right now. Open any one for a full massing study, design options and an MLI Select proforma.
Rental buildings of five or more units can qualify for CMHC's MLI Select program — higher leverage and longer amortization in exchange for affordability, energy-efficiency or accessibility points. Every listing includes an MLI Select proforma so you can see the takeout financing and returns before you buy.
Up to four units (a fourplex) as-of-right on most residential lots, or up to six in the nine EHON pilot wards. Deep lots can add a garden suite, and major-street lots can support a small apartment building.
No. A fourplex is permitted as-of-right on most residential lots city-wide, so no rezoning or minor variance is required for the unit count itself.
A sixplex is a six-unit multiplex. Toronto permits it as-of-right only in nine pilot wards: Parkdale-High Park, Davenport, Spadina-Fort York, University-Rosedale, Toronto-St. Paul's, Toronto Centre, Toronto-Danforth, Beaches-East York, Scarborough North.
