Expert-ready handoff

Take this report to the right professional

Print the report or save it as a PDF, then attach your survey, photos, concept drawings and the official documents linked above.

A Perimtr report is not written legal confirmation, a survey, or a permit determination.

Renovation readiness

Start with the designation by-law, then design around the protected attributes.

A heritage permit is required before work likely to affect a protected attribute. Compatible work may be approved by Heritage Planning staff; major, conflicting or demolition work can require a public Council decision.

Approval loadHigh heritage review

Start with your project

What are you changing?

Pick one item. We’ll show only the approvals most likely to matter.

Windows or doors

Ask before changing

Ask first

A heritage permit is likely if the window or door is a protected feature, or if its size, shape, material or location will change.

For example

Repairing an original wood window is usually easier to approve than replacing it with a different material or making the opening larger.

Likely approvals

Heritage Planning review
Building permit if you create, enlarge or move an opening

Best first step

Send photos and a short description to Heritage Planning before ordering materials.

Need the full picture?Every authority that may be involved

Optional detail

Authorities and their role

“Conditional” means the authority is involved only when the proposed scope triggers its rules.

Heritage Planning

Core

Confirms whether a heritage permit is needed, reviews the design and routes non-delegated applications to the public Council process.

Involved when: Any proposed work that may affect a heritage attribute or district-controlled exterior feature.

Official guidance

Toronto Building

Conditional

Reviews construction, demolition, structural, plumbing, HVAC and change-of-use work under the Building Code and applicable law.

Involved when: Additions, structural changes, new openings, decks, demolition, plumbing/HVAC work or a change of use.

Official guidance

Committee of Adjustment

Conditional

Decides minor variances and consents at a public hearing.

Involved when: The proposal needs modest relief from zoning, such as a setback, height, lot coverage or parking variance.

Official guidance

City Planning & City Council

Conditional

Reviews major planning changes; Council decides rezonings and non-delegated heritage applications.

Involved when: A rezoning, Official Plan change, major development, demolition, or heritage proposal outside delegated staff authority.

Official guidance

Urban Forestry

Conditional

Reviews work that may injure or remove protected trees or affect ravine and natural-feature areas.

Involved when: A private tree is at least 30 cm in diameter, a City tree may be affected, or the site is in a protected ravine area.

Official guidance

Electrical Safety Authority

Conditional

Administers electrical notifications, inspections and Ontario Electrical Safety Code compliance.

Involved when: Almost all electrical installation or alteration work; this approval is separate from the City building permit.

Official guidance

This is a screening guide based on heritage status—not a permit determination. Final requirements depend on the designation by-law or district plan, drawings, zoning, site conditions and the exact scope of work.
