OUR CULTURE
Engineering With Quality and Integrity
At StrongBuilds, we make every structural engineering decision with integrity, objectivity, and a professional responsibility to the people who will live in the buildings we design. That standard doesn’t change whether the project is a simple wall removal in Scarborough or a complex custom home build in Forest Hill.
We hold a Certificate of Authorization from the Professional Engineers of Ontario and maintain errors and omissions insurance of up to $2,000,000 per occurrence. For Toronto homeowners and the professionals they work with, that means complete confidence in every drawing we stamp.
OUR PROCESS
How We Uphold the StrongBuilds Standard in Toronto
Whether you’re a Toronto homeowner navigating the permit process for the first time or a seasoned contractor who needs fast, reliable structural engineering support during an active construction project, our process is designed to keep your project moving safely and efficiently.
Project Consultation and Scoping
We begin by understanding exactly what your Toronto project requires. Whether you need standalone structural drawings for your architect, a complete building permit package for the City of Toronto, or structural support during an active build, we establish a clear scope so nothing falls through the cracks.
Site and Structural Evaluation
Our team evaluates your Toronto property, existing building systems, and structural conditions, including foundation type, load-bearing wall configurations, and site constraints specific to your neighbourhood. For finished interiors, we explicitly document our structural assumptions on the drawings for verification by your contractor on site.
Professional Design and Drafting
We produce P.Eng-stamped structural drawings tailored to your project, ranging from detailed beam and column designs for a load-bearing wall removal to full structural packages for a new custom home or garden suite. All drawings are coordinated with your architectural and HVAC drawings to ensure seamless permit submission.
Final Documentation and Ongoing Support
We deliver all technical documents, structural calculations, and stamped drawings required by the City of Toronto or your construction team. We handle minor revision requests from permit examiners at no additional charge and remain available throughout the construction project for design questions and site inspections.

OUR WORK
Residential Structural Engineering Projects Across Toronto
StrongBuilds has completed structural engineering work on residential buildings throughout Toronto, including projects in Leslieville, Scarborough, Etobicoke, North York, and the Annex. The following selection of completed projects reflects the range of work we deliver across the city.
LESLIEVILLE
Project Alton
Complete main-floor gut with open-concept structural wall removals, an increased rear wall opening for a sliding door, and load-bearing wall engineering. This project is representative of the renovation work we deliver throughout Toronto’s east-end neighbourhoods.
ETOBICOKE
Project Renown
A two-storey garden suite with masonry veneer, two bedrooms, and three bathrooms on an Etobicoke lot. This project required coordinated architectural, structural, and HVAC drawings for a single permit submission to the City of Toronto.
SCARBOROUGH
Project Norbury
This project featured a challenging underpinning scope that included crawl space conversion, interior column removals, and a reinforced concrete retaining wall. These are common structural challenges for Toronto’s older post-war housing stock in areas like Scarborough and North York.
YORK MILLS & BAYVIEW
Project Zaha
Structural engineering for a major interior remodel featuring large vaulted ceilings across the kitchen and living areas, a cathedral ceiling within a study, and comprehensive load-bearing wall removals throughout the main floor.
AVENUE & LAWRENCE
Project Elm
Multi-directional additions to a Toronto home featuring cathedral ceilings, an overhanging second floor above patio space, a basement walkout, and large glazed openings. This complex structural scope required precise load path engineering.
ETOBICOKE
Project Laurelwood
Structural engineering for a complete interior gut, creating vaulted ceilings and an open-concept layout across living, dining, and kitchen areas. We achieved this through carefully engineered load-bearing wall removals and replacement beam designs.

FAQs
Frequently Asked Questions
Do I need a structural engineer for a renovation in Toronto?
Yes, in most cases. Any modification to load-bearing walls, foundations, or structural elements in a Toronto home requires engineering drawings stamped by a licensed Professional Engineer (P.Eng). This is a requirement of both the Ontario Building Code and the City of Toronto’s building permit process. Beyond regulatory compliance, engaging a licensed structural engineering firm ensures your design is safe and protects your home insurance coverage.
How long does it take to get a building permit in Toronto?
The City of Toronto typically responds to residential permit applications within 10 to 14 business days for smaller scopes such as wall removals or accessory structures. Initial reviews for larger projects, including additions, custom homes, and garden suites, may take 4 to 6 weeks. Responses may include permit issuance, a request for information (RFI), or a revision request, which StrongBuilds addresses promptly and at no additional charge for minor changes within the original scope.
Can StrongBuilds handle wall removals in older Toronto homes with finished walls?
Absolutely. This is one of the most common scenarios we encounter across Toronto’s older housing stock. When walls are finished, and structural conditions aren’t directly visible, we make explicit, documented structural assumptions based on the home’s geometry, age, and our experience with similar building systems in Toronto. These assumptions are noted on the engineering drawings and verified on site by the contractor after demolition, with revisions provided promptly if conditions differ.
What do you include in your structural engineering package for Toronto projects?
A typical StrongBuilds package for a Toronto permit application includes P.Eng-stamped structural drawings, structural calculations, Schedule 1 and general review commitment forms, and any site-specific documentation required by the City of Toronto. For complete permit packages involving garden suites, custom homes, or complex additions, we also coordinate architectural and HVAC drawings as a unified submission.
Can you help with basement underpinning in a Toronto semi-detached home?
Yes. Semi-detached and attached homes are among the most common underpinning projects we complete in Toronto. Underpinning a shared party wall requires a written agreement from your neighbour before a permit can be issued. If you can’t obtain that agreement, StrongBuilds designs a benching or hybrid underpin/benching solution that achieves the maximum ceiling height gain without encroaching on the party wall and stays within the City of Toronto’s permit requirements.
What makes StrongBuilds different from a drafting service?
The Professional Engineers of Ontario authorize a licensed structural engineer to take professional responsibility for a structural design. Our P.Eng-stamped drawings are legally accepted by the City of Toronto for permit applications and carry accountability for safety and code compliance. A drafting service cannot stamp structural drawings, cannot take professional responsibility for the design, and in many cases cannot represent you through the technical review process with the city’s building division.
Do you work on projects in North York, Etobicoke, and Scarborough?
Yes. StrongBuilds provides structural engineering services across the entire City of Toronto, including North York, Etobicoke, Scarborough, East York, and all downtown and midtown neighbourhoods. We have completed projects throughout these areas and are familiar with the building stock, lot conditions, and permit requirements specific to each part of the city.
