A development application in Markham typically requires between 9 and 15 supporting studies under Comprehensive Zoning By-law 2024-19, confirmed at the Pre-Application Consultation Request (PRCN) stage submitted through the ePLAN portal. The Toronto and Region Conservation Authority (TRCA) holds jurisdiction over southern Markham, and York Region co-approves all Official Plan Amendments.
Markham replaced its Pre-Application Consultation process with a Pre-Application Consultation Request (PRCN) in 2022, routed through Markham's ePLAN portal. An applicant who files a paper PRCN or uses the wrong portal form receives a deficiency notice and is rescheduled, adding weeks before the pre-consultation meeting. Comprehensive Zoning By-law 2024-19 came into force in mid-2024 and superseded the prior zoning instruments across most of the city. Applications prepared under a predecessor bylaw that reference superseded zone classifications are returned as fundamentally flawed.
York Region co-approves all Official Plan Amendments for Markham, as Markham is a lower-tier municipality within York Region. The Toronto and Region Conservation Authority (TRCA) holds jurisdiction across southern Markham. The Lake Simcoe Region Conservation Authority (LSRCA) holds jurisdiction over the northern portions of the city near the Lake Simcoe watershed boundary.
Markham 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 Request (PRCN) stage.
| Body | Application types |
|---|---|
| City of Markham — Planning and Urban Design | SPC, ZBA, OPA, Subdivision, Condominium, Consent, Variance |
| York Region | SPC, ZBA, OPA, Subdivision |
| Toronto and Region Conservation Authority | SPC, ZBA, OPA, Subdivision |
| Lake Simcoe Region Conservation Authority | SPC, ZBA, OPA, Subdivision |
| York Region District School Board | Subdivision |
| York Catholic District School Board | Subdivision |
| Parks Canada (Rouge National Urban Park) | OPA, ZBA, SPC |
Markham's approval process runs through two mandatory gating stages before any Council decision: a Pre-Application Consultation Request (PRCN) that confirms the required study list, and a complete application submission that starts the statutory clock. Both are sequential.
Submit a Pre-Application Consultation Request (PRCN) request through the City's portal or intake process. City Planning assigns a planner and schedules the meeting within 20 business days. No planning application is accepted without completing this step.
City staff and triggered agency representatives attend. The output confirms all required studies, drawings, and the full agency circulation list. This document is the authoritative checklist for 1st submission.
Engage specialized consultants for each study confirmed at the meeting. Major studies have lead times of 8 to 14 weeks. Begin immediately after the study output is received.
Assemble all studies, architectural drawings, and supporting documents. A typical ZBA commenting package runs 15 to 25 items. All files must meet City specifications on naming, format, and file size.
City Planning accepts only complete packages. A complete application triggers the 90-day statutory review clock for ZBA, or the 120-day clock for a concurrent OPA and ZBA, immediately on acceptance.
City Planning circulates the commenting package to all triggered agencies simultaneously. Each agency reviews independently. Typical turnaround is 8 to 14 weeks per agency.
City Planning compiles all agency comments. The applicant submits a revised commenting package and response matrix addressing each comment from each agency.
City Planning holds a required public meeting for OPA and ZBA applications under the Ontario Planning Act. Notice is mailed to all property owners within the required radius at least 15 days in advance.
Planning committee reviews the staff report and recommendation. Council votes. Any party with standing may appeal to the Ontario Land Tribunal (OLT) within 20 days of the Council decision.
Statutory minimums under the Ontario Planning Act. Actual timelines depend on application complexity, agency comment volume, and OLT appeal activity.
Studies are confirmed at the Pre-Application Consultation Request (PRCN) stage and vary by site characteristics, proposed use, and triggering conditions specific to the property. The tables below cover verified study requirements from PreBuildIQ's dataset for Markham applications under Comprehensive Zoning By-law 2024-19.

Look up my address →Markham development applications require between 8 and 20 studies depending on site characteristics, proposed use, and triggering conditions. Always required for ZBA and OPA applications under Comprehensive Zoning By-law 2024-19: Planning Justification Report, Functional Servicing and Stormwater Management Report, Transportation Impact Study, Geotechnical Investigation, Noise Impact Study, Archaeological Assessment, and Environmental Site Assessment. The complete list is confirmed at the Pre-Application Consultation Request (PRCN) stage based on the specific property.
Markham planning applications are circulated to multiple agencies depending on site characteristics. Standard agencies include the City Planning Department, Toronto and Region Conservation Authority (TRCA), and (where applicable) the upper-tier regional municipality. Additional agencies are triggered by specific site conditions confirmed at the Pre-Application Consultation Request (PRCN) meeting. Not all agencies comment on every application.
The Pre-Application Consultation Request (PRCN) process in Markham typically takes 4 to 8 weeks from the initial request to receipt of the written output confirming the required study list and agency circulation. City Planning assigns a planner within 20 business days of the request. The meeting itself is then scheduled and held. The written study scope confirmation follows the meeting and is the authoritative document for preparing a 1st submission.
A complete Markham planning application requires all studies and drawings listed in the Pre-Application Consultation Request (PRCN) output, plus all application forms, fees, and supporting documents required by the planning fee schedule. City Planning will not issue a receipt, and the statutory review clock will not start, until the application is accepted as complete. An application returned as incomplete must be resubmitted with all deficiencies addressed before the clock starts.
An incomplete Markham planning application is returned without a receipt, and the statutory review clock does not start. The applicant must resubmit a complete commenting package, which restarts agency circulation from the beginning. Common reasons for returns: missing studies confirmed at the Pre-Application Consultation Request (PRCN) stage, outdated environmental assessments, missing drawing elements, and incomplete application forms. Each resubmission cycle typically adds 6 to 12 weeks to the project timeline.
Markham charges a fee for the Pre-Application Consultation Request (PRCN) process, with the exact amount depending on the application type and the scale of the proposed development. The fee schedule is updated periodically and is available from the City Planning Department. In most Ontario municipalities, the pre-consultation fee is credited against the final planning application fee paid at 1st submission, so it is not an additional cost but an advance payment.
Missing one study at 1st submission resets the statutory clock. At $43,000 per month in carrying costs on a stalled GTA project, that is a measurable loss. Enter your Markham address and PreBuildIQ generates your complete required-study and agency list instantly.
