Development approvals in Markham require Planning and Urban Design Department review under Comprehensive Zoning By-law 2024-19, with all applications submitted through the ePLAN portal. York Region co-approves all Official Plan Amendments. Applications near the Rouge River corridor may also trigger Parks Canada regulatory jurisdiction under the Canada National Parks Act.
Markham is one of the few Ontario municipalities where a development application near the Rouge River watershed can trigger a dual review by both the Toronto and Region Conservation Authority (TRCA) in the south and Parks Canada, which holds regulatory authority over development near Rouge National Urban Park in the eastern portions of the city. Parks Canada's permit under the Canada National Parks Act runs independently of TRCA's provincial permit and has different standards, timelines, and conditions.
An application that requires both a TRCA permit and a Parks Canada permit must manage two separate regulatory tracks simultaneously, each with its own environmental review requirements. A developer who identifies only the TRCA trigger and not the Parks Canada trigger at the PRCN stage proceeds with incomplete agency circulation and receives a stop-work notice after Building Permit issuance when the Parks Canada requirement is identified.
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.
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.
Submit through the designated portal or intake. City Planning confirms the application type, required study scope, and agency circulation list for the specific site.
Engage consultants for each study confirmed at the Pre-Application Consultation Request (PRCN) stage. Prepare architectural drawings to the pre-application concept level. Major studies have 8 to 14 week lead times.
Assemble all studies, drawings, and supporting documents per the City's completeness checklist. Calculate fees based on the current planning fee schedule.
A complete application triggers the statutory review clock. An incomplete application is returned without a receipt and no clock starts.
City Planning circulates the commenting package to all triggered agencies simultaneously. Typical agency review runs 8 to 14 weeks per agency.
Submit a revised package and response matrix. Multiple revision cycles are common on complex applications. Upper-tier municipality comments (where applicable) require separate responses.
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.
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.
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.

Look up my address →Before filing any planning application in Markham, a Pre-Application Consultation Request (PRCN) 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 Comprehensive Zoning By-law 2024-19. 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.
Most OPA and ZBA applications in Markham 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.
Planning applications in Markham 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 Request (PRCN) 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.
A Zoning By-law Amendment (ZBA) changes the zoning of a specific property under Comprehensive Zoning By-law 2024-19 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.
A minor variance addresses a small, site-specific deviation from a specific performance standard in Comprehensive Zoning By-law 2024-19 (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.
An Official Plan Amendment is required in Markham 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 Request (PRCN) confirms whether an OPA is required or whether a standalone ZBA is sufficient for the specific site and proposal.
The wrong approval type means starting over. At $43,000 per month in carrying costs, a misidentified approval path is a six-figure mistake. Enter your Markham address and PreBuildIQ identifies the required approval type and study list in 60 seconds.
