Multiplex Builds and Land Development in the GTA
Leedway Group takes residential land from raw parcel to finished units across the Greater Golden Horseshoe: multiplexes, severances, rezoning, site plan approval and small townhome and condo developments, with feasibility checked before you commit.
Toronto now allows four units as-of-right on many lots, and Ontario requires at least three units as-of-right on most serviced residential lots.

Multiplex and Development FAQs
Possibly. Toronto allows up to four units as-of-right on many residential lots, and Ontario requires at least three on most serviced lots. Lot size, servicing and the local zoning still decide what fits, so we start with a feasibility review.
GTA hard costs for this type of building run about $180 to $270 per square foot in 2026, excluding land, design fees and development charges.
Once the application is complete, the approval authority has a 90-day decision window. Conditions must then be met within two years. Fees for one new lot range from $2,882 in Mississauga to $8,080.65 in Toronto.
A minor variance covers a small departure from one zoning rule, such as a setback. A rezoning changes what the zoning allows on the land and involves a public meeting and a council vote. We tell you which applies after the feasibility review.
Check zoning, servicing and approval risk before you sign. Through Leedway Realty we can help you find and buy a site and confirm what it can yield before closing.
Projects include rezoning and site work for a 70-unit condo in Niagara, the Ritson Homes development and the DiPietro Homes townhome development. See all projects.
