Multiplexes in North York

North York is postwar Toronto, Willowdale and the Yonge (Line 1) and Sheppard (Line 4) corridors, laid out with wide, deep lots on quiet streets. That extra room suits a fourplex new-build and leaves rear-yard space for a garden suite near the subway. North York is not one of the nine sixplex wards, so the city-wide ceiling of four units applies unless a ward opts in. Pull the per-neighbourhood numbers from the City's Neighbourhood Profiles.

Key Takeaways

  • Wide, deep postwar lots suit a fourplex new-build with rear-yard room to spare.
  • Willowdale sits on the Yonge subway (Line 1); the Sheppard line (Line 4) runs east.
  • Four units as-of-right, North York is not a sixplex ward unless it opts in.
  • Deep rear yards make a garden suite the natural added unit.

On the larger North York lots the binding limit is usually the envelope rather than the area. See which one binds on your lot .

Where these applications stand

Of 218 applications in North York, 150 have an issued permit, 40 are still under review, and 28 were refused, cancelled or abandoned. A filed application is not a permit, so the totals on this page count applications rather than approvals.

Taken from the City's own status value on each permit, not from which dataset it appears in.

New homes each project adds

Counts new homes added, not homes in the finished building. Demolishing a house and building a fourplex in its place adds three, not four.

What builders declared it would cost

Across 192 projects in North York that state both a value and between two and six new homes, the declared construction cost runs from $500,000 at the 25th percentile to $1,300,000 at the 75th, with a median of $900,000.

This is the figure the applicant wrote on the permit application. It is not a sale price, it is not the final cost of the build, and it does not include the land.

How long the City took to issue

Of the 218 projects in North York, 162 have been issued. Those took a median of 83 days from application, with a quarter issued within 50 days and a quarter taking longer than 136. 56 are still waiting and are not in that median.

Application to issue, from the City's own dates. Projects still under review are excluded rather than counted at how long they have waited so far, which would understate the real wait.

Why North York Fits Multiplex Infill

Large postwar lots

North York was built after the war, on wide and deep lots laid out for detached houses on quiet streets. That extra width and depth gives a fourplex new-build more room to work than the narrow lots of the old core, and leaves rear-yard space for a garden suite.

Two subway lines

Willowdale sits on the Yonge subway (Line 1), and the Sheppard line (Line 4) runs east from it. A lot within a walk of either line is exactly where new ground-oriented housing makes sense, and parking minimums no longer force a multiplex to give up lot area.

Fourplex unless the ward opts in

North York is not one of the nine sixplex wards. Up to four units are permitted as-of-right here, the city-wide ceiling. Six units would only be possible if a North York ward councillor opted into the sixplex permissions, so plan around four unless your ward has done so.

Best For

  • Wide, deep postwar lots where a fourplex new-build sits comfortably.
  • Sites within a walk of the Yonge or Sheppard subway lines.
  • Lots with deep rear yards where a garden suite adds a unit.

Usually Fails When

  • A sixplex is assumed, but North York is outside the nine wards unless it opts in.
  • A garden suite is planned without confirming the rear-yard depth.
  • A new-build design exceeds the as-of-right envelope and the variance timeline was not planned.

What To Verify Before Spending Money

  • The residential zone and Neighbourhoods designation for the parcel.
  • Whether the North York ward has opted into sixplex permissions (otherwise four units).
  • Lot dimensions and rear-yard depth for a fourplex plus a garden suite.

Where to Go Next

Frequently Asked Questions

Can I build a sixplex in North York? +
Not as-of-right. North York is not one of the nine wards where the City permitted up to six units in June 2025. The city-wide ceiling of four units applies here. A North York lot could only go to six if its ward councillor opted into the sixplex permissions. Plan for a fourplex unless you confirm an opt-in for the specific ward.
Why do North York lots suit a fourplex new-build? +
North York is postwar, laid out with wide and deep lots for detached houses on quiet streets. That gives a fourplex new-build more room to sit comfortably than the narrow lots of the old core, and it leaves rear-yard space for a garden suite. Up to four units are permitted as-of-right on any residential Neighbourhoods lot.
Is Willowdale a good place to build a multiplex? +
Willowdale sits on the Yonge subway (Line 1) with wide postwar lots, which suits a fourplex new-build near transit. Up to four units are permitted as-of-right; six are not, since the area is outside the nine sixplex wards. A garden suite can add a unit in the rear yard. Check the specific lot against the City's Neighbourhood Profiles.
Do North York lots work for garden suites? +
Often, yes. The deep rear yards typical of postwar North York lots are what a garden suite needs, a detached unit in the back yard on a lot without a public laneway. Most North York streets were not platted with rear lanes, so a garden suite is usually the right fit rather than a laneway suite. Confirm the lot's depth before planning.
Does a lot near the Sheppard line qualify for the same permissions as one near the Yonge line? +
Yes. Both Line 1 (Yonge) and Line 4 (Sheppard) sit inside North York, and the four-unit as-of-right permission applies the same regardless of which subway line the lot is near. Being within a walk of either line supports the case for a fourplex new-build, since parking minimums no longer force the site to give up lot area.
What is the biggest risk when designing a fourplex on a wide North York lot? +
The biggest risk is a design that exceeds the as-of-right building envelope without planning for the variance timeline that follows. North York's wide, deep postwar lots invite a larger fourplex, but the four-unit permission does not remove the envelope rules on height, setbacks, and lot coverage that still apply to the site.
What should I verify before committing to a North York fourplex plan? +
Verify the residential zone and Neighbourhoods designation for the parcel, whether the specific ward has opted into sixplex permissions, and the lot dimensions and rear-yard depth needed for a fourplex plus a garden suite. North York defaults to four units as-of-right, so these checks confirm the lot supports the plan before design starts.
How close to the subway does a North York lot need to be for a multiplex to make sense? +
Close enough to walk to a Line 1 or Line 4 station, since that walkability is what let the City remove parking minimums for small multiplexes in North York. A lot outside walking distance of Willowdale or the Sheppard corridor still carries the four-unit as-of-right permission, but the transit case for the project is weaker.
