How Does Real Estate Development Work in Ontario? A Step-by-Step Guide

What Real Estate Development Actually Involves

When people picture real estate development, they picture construction: cranes, concrete, framing, and eventually a completed building. But construction is only one stage of a much longer process.

Long before a shovel hits the ground, a development team must identify the right property, determine what can be built, understand municipal planning requirements, test financial feasibility, design the project, secure approvals, arrange financing, and manage dozens of technical considerations.

In many cases, some of the most important decisions affecting a project's success happen before construction even begins.

So how does real estate development actually work in Ontario? While every project and municipality is different, most developments move through several key stages.

The Real Estate Development Process in Ontario, Step by Step

Step 1: Identifying a Potential Development Site

Every development begins with land. But finding a property for sale is very different from finding a property that works for development.

Before acquiring a site, a developer will typically investigate questions such as: What does the municipality's Official Plan envision for this area? What is the property currently zoned for? What uses are permitted? How much density could potentially be achieved? What height and setback restrictions apply? Are municipal water, sewer, road, and other services available? Are there environmental, heritage, conservation, access, or servicing constraints? What is happening in the surrounding neighbourhood? Is there sufficient demand for the proposed use?

The goal is not simply to find land. It is to determine whether the land can support a viable project. This early-stage analysis is one reason experienced development teams evaluate a property very differently from someone simply purchasing an existing building.

Step 2: Understanding the Official Plan and Zoning

Two of the most important concepts in Ontario development are the Official Plan and zoning bylaw.

An Official Plan establishes a municipality's broader policies for how land should be used and how the community should grow. It can address where housing, employment, commercial uses, infrastructure, parks, roads, and other community services should be located.

A zoning bylaw is more specific. It establishes legally enforceable rules governing matters such as permitted land uses, building types, building height, density, setbacks, lot dimensions, and parking requirements.

A proposed development may already comply with the property's existing planning permissions. In other cases, changes may be required before the proposed project can proceed.

Understanding this planning framework early is critical because what can legally be built on a property can be very different from what initially appears possible.

Step 3: Testing Development Feasibility

A property can be developable and still be a poor development opportunity.

Before proceeding, developers typically build a financial model, often called a development pro forma, to determine whether the project is economically viable. The analysis may consider land acquisition cost, number and type of units, expected rents or sale prices, construction costs, professional consultant costs, municipal fees and development charges, financing costs, project timelines, operating assumptions, contingencies, and expected project value.

These variables interact with one another. For example, adding units may increase revenue, but it can also change parking requirements, servicing requirements, building systems, construction costs, and approval complexity.

Development therefore involves continuously balancing design, planning, financing, construction, and economics. A successful project needs to work on paper before it can work in the ground.

Step 4: Due Diligence

Before committing significant capital to a development site, the team typically conducts detailed due diligence.

Depending on the property and proposed development, this may involve specialists such as architects, planners, civil engineers, structural engineers, mechanical and electrical engineers, geotechnical engineers, environmental consultants, transportation consultants, surveyors, lawyers, and cost consultants.

The team is looking for issues that could materially affect the project's feasibility. Examples could include soil conditions, environmental concerns, servicing capacity, access constraints, title matters, easements, grading, stormwater requirements, or other site-specific conditions.

The earlier these issues are discovered, the more effectively they can be incorporated into the project's design, budget, and strategy.

Step 5: Designing the Project

Once the development concept has been validated, the design process becomes increasingly detailed. Architecture at this stage is about much more than appearance.

The design needs to respond simultaneously to municipal planning requirements, Building Code requirements, site constraints, unit layouts, accessibility, structural systems, mechanical and electrical systems, constructability, energy performance, parking and circulation, landscaping, waste management, and project economics.

This is where coordination becomes extremely important. A design decision that looks minor on an architectural drawing can have consequences for structural engineering, mechanical systems, construction cost, financing, or the number of rentable units.

For this reason, development works best when design and financial feasibility evolve together rather than as separate exercises.

Step 6: Municipal Planning Approvals

Depending on the property and project, one or more municipal planning approvals may be required. These can include processes such as Official Plan amendments, zoning bylaw amendments, minor variances, site plan approval, and plans of subdivision or consent where applicable.

Not every project requires every approval. The specific process depends on the site, existing permissions, proposed development, and municipality.

Municipal review can also involve input from multiple departments and outside agencies. Depending on the application, issues under review may include servicing, transportation, drainage, landscaping, access, compatibility with surrounding properties, and other site-specific considerations. For some applications, public consultation and opportunities for appeal may also form part of the planning process.

This stage can significantly affect a project's overall timeline.

Step 7: Site Plan Approval and Detailed Coordination

For developments subject to site plan control, the municipality reviews detailed elements of how the development will function on the property. These can include matters such as building location, vehicle access, pedestrian circulation, landscaping, lighting, waste and recycling areas, parking and loading, drainage, and exterior site design.

By this point, the project is moving from a development concept toward something increasingly detailed and buildable. Engineering, architecture, planning, and municipal requirements must all be coordinated.

Step 8: Arranging Development and Construction Financing

Real estate development is capital intensive. A project may require capital for land acquisition, design and consultants, municipal approvals, development charges and fees, construction, financing costs, leasing, and contingencies.

Developers therefore need to determine how the project will be capitalized. The exact structure varies from project to project, but development capital can include developer equity, investor equity, and debt financing.

Lenders will typically evaluate the project's economics, approvals, construction budget, development team, market assumptions, and other risk factors before committing capital.

Financing is therefore not simply something arranged after a building has been designed. Financing considerations can influence the project much earlier in the development process.

Step 9: Building Permit

Planning approval and a building permit are not the same thing.

Planning approvals determine whether and how a property can be developed. A building permit allows the approved construction to proceed once the proposed work complies with the Ontario Building Code and other applicable laws.

A building permit application typically requires detailed drawings and documentation. Municipal building officials review the application before issuing the permit. If required planning approvals have not been obtained, or the proposed construction does not comply with applicable requirements, the building permit cannot simply be issued.

Step 10: Construction

Construction, the stage most closely associated with development, begins only after a substantial amount of preparatory work has already taken place, work that can span months or years depending on the project's complexity.

Construction typically involves site preparation, excavation, foundations, structure, building envelope, mechanical and electrical systems, interior construction, landscaping, testing, inspections, and commissioning.

During construction, the development team must continuously manage budget, schedule, design coordination, contractor performance, changes, inspections, financing draws, and unforeseen conditions. The drawings may be complete, but decision-making certainly is not.

Step 11: Occupancy and Stabilization

Completing construction is not necessarily the end of the development process.

For a purpose-built rental development, the next stage includes leasing the property and moving toward stabilized operations. This can involve unit turnover and deficiency correction, tenant occupancy, property management, operating systems, rent collection, building maintenance, and final project closeout.

A rental property is generally considered stabilized once it has reached a sustainable level of occupancy and established normal operating performance. At this point, the project has transitioned from development into an operating real estate asset.

How Long Does Real Estate Development Take in Ontario?

There is no universal timeline. The duration depends heavily on factors such as project size, existing zoning, required planning approvals, municipal review, site complexity, environmental or servicing issues, financing, construction type, and market conditions.

A relatively straightforward project using existing permissions may progress much faster than a project requiring substantial planning changes or complex infrastructure. This is why experienced developers spend considerable time evaluating approval and execution risk, not simply construction cost.

Where Is Value Actually Created in Development?

One of the biggest misconceptions about real estate development is that value is created primarily during construction.

Construction converts plans into a physical building, but many of the decisions determining whether that building will be successful happen earlier.

Value can be influenced through selecting the right site, understanding planning permissions, determining appropriate density, creating an efficient design, managing approval risk, selecting the right building systems, controlling construction costs, structuring financing appropriately, designing for the eventual occupant, and coordinating the development team effectively.

By the time construction begins, many of the project's most consequential decisions have already been made. That is why we believe the biggest decisions in development often happen before the shovel hits the ground.

Why an Integrated Development Team Matters

Real estate development brings together architecture, planning, engineering, construction, finance, legal work, and operations.

When those disciplines operate independently, decisions made in one area can create unintended consequences somewhere else. An architectural change may affect structural costs. A planning decision may affect financing. A mechanical system may change construction costs and long-term operating expenses. A financing requirement may influence the project's design.

The challenge is not simply having good consultants. It is getting the right people making decisions together at the right time.

At Biosis Real Estate Development, this philosophy shapes how we approach projects. By integrating development, architecture, engineering coordination, underwriting, and project management, we aim to evaluate major decisions through multiple lenses from the earliest stages of a project.

The Bottom Line

Real estate development in Ontario is not simply a construction process. It is a coordinated sequence of site selection, due diligence, planning, design, financial analysis, approvals, financing, construction, and operations.

Each stage affects the next. And while construction is the most visible part of development, many of the decisions that determine a project's feasibility, risk, and long-term performance happen much earlier.

Understanding that process is the first step toward understanding how real estate development actually creates value.
