Toronto Development Approval Process: Agencies, Studies, and Timelines

Quick Answer

Development approvals in Toronto require City Planning Division review and circulation to as many as seven agencies, including the Toronto and Region Conservation Authority (TRCA) and Toronto Transit Commission (TTC). Most OPA and ZBA applications take 18 to 24 months from 1st submission to Council approval, with a statutory 90-day clock for standalone ZBA applications under Zoning By-law 569-2013.

Toronto operates through five distinct planning districts, each with a separate Community Planner roster and varying internal review timelines. A ZBA application submitted to the wrong district intake gets rerouted but does not trigger the 90-day statutory clock until the file is formally assigned, which can add 3 to 4 weeks. Toronto Heritage Preservation Services (HPS) holds jurisdiction over more than 8,000 listed properties. An application adjacent to a listed property that omits the Heritage Impact Assessment is returned as incomplete at intake, resetting the review to day zero.

Toronto is a single-tier municipality with no upper-tier co-approval requirement, but the City circulates applications to as many as seven agencies simultaneously. Each agency reviews independently. A single agency comment that requires a study revision triggers a full recommissioning cycle and adds to the carrying cost on a stalled project.

Approval Bodies in Toronto

Toronto planning applications are circulated to multiple approval bodies depending on site characteristics and application type. Triggers are site-specific and confirmed at the Pre-Application Consultation (PAC) stage.

The Toronto Approval Process: Step by Step

Toronto's approval process runs through two mandatory gating stages before any Council decision: a Pre-Application Consultation (PAC) that confirms the required study list, and a complete application submission that starts the statutory clock. Both are sequential.

  1. 1
    Determine the required approval type

    Confirm whether a ZBA, OPA, SPC, Subdivision, or a combination is needed based on the proposed use and current zoning. An incorrect filing is returned without a receipt.

  2. 2
    Request a Pre-Application Consultation (PAC)

    Submit through the designated portal or intake. City Planning confirms the application type, required study scope, and agency circulation list for the specific site.

  3. 3
    Commission required studies

    Engage consultants for each study confirmed at the Pre-Application Consultation (PAC) stage. Prepare architectural drawings to the pre-application concept level. Major studies have 8 to 14 week lead times.

  4. 4
    Prepare a complete application

    Assemble all studies, drawings, and supporting documents per the City's completeness checklist. Calculate fees based on the current planning fee schedule.

  5. 5
    1st submission

    A complete application triggers the statutory review clock. An incomplete application is returned without a receipt and no clock starts.

  6. 6
    Agency review and comment period

    City Planning circulates the commenting package to all triggered agencies simultaneously. Typical agency review runs 8 to 14 weeks per agency.

  7. 7
    Respond to agency comments

    Submit a revised package and response matrix. Multiple revision cycles are common on complex applications. Upper-tier municipality comments (where applicable) require separate responses.

  8. 8
    Statutory public meeting

    Required for OPA and ZBA applications under the Ontario Planning Act. Notice is mailed to owners within the required radius at least 15 days before the meeting.

  9. 9
    Decision and OLT appeal window

    Staff recommendation goes to Council or a delegated approver. Any party with standing may appeal to the Ontario Land Tribunal (OLT) within 20 days of the decision.

Planning Note
A mixed-income development in the Yonge-Eglinton Secondary Plan area submitted a ZBA application without realizing the site was within 30 metres of a TRCA-regulated tributary. City Planning returned the application as incomplete at intake. The developer commissioned a Natural Heritage Impact Study and resubmitted six weeks later. The carrying cost during the delay was approximately $258,000.

Frequently Asked Questions

What approvals are required before filing a development application in Toronto?

Before filing any planning application in Toronto, a Pre-Application Consultation (PAC) is required to confirm the application type and study scope. The type of approval depends on the proposed use and how it relates to the current zoning under Zoning By-law 569-2013. A use permitted by right requires only Site Plan Control. A use requiring a zoning change requires a ZBA. A use not permitted by the Official Plan requires a concurrent OPA. Misidentifying the approval type produces a fundamental application deficiency that requires refiling.

How long does a development application take in Toronto, Ontario?

Most OPA and ZBA applications in Toronto take 14 to 24 months from 1st submission to Council approval, depending on the complexity of the application, the number of agency comments received, and whether an OLT appeal is filed. The statutory minimum under the Ontario Planning Act is 90 days for a standalone ZBA and 120 days for a concurrent OPA and ZBA. These statutory minimums reflect when an applicant can escalate to the OLT if no decision has been made, not when decisions are typically rendered.

Which agencies comment on planning applications in Toronto?

Planning applications in Toronto are circulated to the Toronto and Region Conservation Authority (TRCA), the upper-tier regional municipality (where applicable), and additional agencies triggered by site-specific characteristics confirmed at the Pre-Application Consultation (PAC) stage. Standard agency commentors include the conservation authority and any applicable utilities. Additional agencies are triggered by proximity to transportation infrastructure, natural heritage features, or heritage properties. Not all agencies comment on every application.

What is the difference between a ZBA and an OPA in Toronto?

A Zoning By-law Amendment (ZBA) changes the zoning of a specific property under Zoning By-law 569-2013 to permit a use or built form that is not currently allowed. An Official Plan Amendment (OPA) changes the land use designation in the Official Plan, which sets higher-level land use policies. If a proposed development requires both a zoning change and an Official Plan policy change, a concurrent OPA and ZBA application is required. Concurrent applications trigger a 120-day statutory clock rather than the 90-day ZBA-only clock.

What is the difference between a minor variance and a zoning bylaw amendment in Toronto?

A minor variance addresses a small, site-specific deviation from a specific performance standard in Zoning By-law 569-2013 (setback, height, lot coverage, parking). It is decided by the Committee of Adjustment under Section 45 of the Ontario Planning Act and does not require City Council approval. A ZBA changes the zoning category, permitted uses, or by-law performance standards for a property and requires City Council approval. A ZBA is the right approval when the proposed deviation is significant, when the use is not permitted, or when a policy change is also required.

What triggers an Official Plan Amendment requirement in Toronto?

An Official Plan Amendment is required in Toronto when the proposed development involves a land use not permitted by the current Official Plan designation for the site, or when the proposed density, height, or built form exceeds what is permitted by the Official Plan for that land use designation. Secondary Plan areas may have additional OPA triggers specific to the Secondary Plan policies. A Pre-Application Consultation (PAC) confirms whether an OPA is required or whether a standalone ZBA is sufficient for the specific site and proposal.
