Understanding the Role of the "Constructor" on a Job Site in Ontario
If you’re planning to build a home or renovate a property in Ontario, you’ve likely heard the term “constructor” used in legal or construction documents. But what does it really mean—and why does it matter?
Let’s break it down.
What is a Constructor Under Ontario Law?
In Ontario, the Occupational Health and Safety Act (OHSA) defines a "constructor" as:
“A person who undertakes a project for an owner and is responsible for ensuring that the work complies with the OHSA and its regulations.”
In other words, the constructor is legally responsible for overall health and safety on a construction project site. This person or company coordinates all the work and ensures that all contractors and workers follow safety laws.
Important Note: This definition is legal, not just a job title. The term “constructor” doesn’t mean “builder” or “general contractor” in the casual sense. It’s a specific legal role with serious responsibilities.
Constructor vs. General Contractor: Are They the Same?
Not always.
If only one contractor is working on the project, they may also be the constructor. But if multiple contractors or trades are on site at the same time, one party must be designated as the constructor. In many residential projects, the general contractor becomes the constructor by default because they are managing all sub-trades. However, if the homeowner hires each trade separately (e.g., a plumber, electrician, and roofer independently), the homeowner may legally become the constructor—even if they don’t realize it.
Why Does It Matter?
Being designated the constructor comes with legal liability under the OHSA. That means the constructor is responsible for:
Ensuring safe working conditions
Coordinating site activities
Making sure workers are trained and protected
Reporting accidents and injuries
Complying with all Ministry of Labour, Immigration, Training and Skills Development (MLITSD) requirements
Failure to meet these responsibilities can lead to fines or prosecution.
What It Means for Homeowners
If you’re a homeowner managing your own build or renovation—especially if you’re hiring trades directly—you might unintentionally take on the role of constructor under the law.
That’s why it’s critical to work with a licensed and experienced general contractor who will act as the constructor and handle all compliance responsibilities on your behalf.

Body Cameras in Construction: Enhancing Transparency, Safety, and Accountability
Adding a Home Addition Advantages - Cost-Effectiveness: One of the primary benefits of opting for a home addition is its cost-effectiveness. Expanding your current property often proves to be more economical than purchasing a new house. By selecting a home addition, you can sidestep expenses like realtor commissions, closing costs, land transfer taxes, new home start up fees, general personalized renovation work and moving fees. - Preservation of Sentimental Value: Your existing home may hold significant sentimental value due to shared memories and experiences. Through a home addition, you can uphold this emotional connection by creating additional living space that caters to your evolving needs, all without leaving cherished memories behind. - Customization and Personalization: A home addition grants you the freedom to design and personalize the new space to meet your specific requirements and preferences. Whether it's an expanded kitchen, an extra bedroom, or a home office, the addition can be tailored perfectly to suit your lifestyle. - Avoiding Relocation Stress: Moving to a new house involves considerable stress and effort. Opting for a home addition allows you to bypass the challenges of house hunting, packing, and adapting to a new neighborhood. Disadvantages - Limited Space Potential: Adding a home addition is constrained by the available space on your property. Depending on your lot size and local zoning regulations, there may be limitations on how much you can expand your home. - Disruption during Construction: Undertaking a home addition involves construction on your property, leading to noise, dust, and disruption to your daily life until the project is completed. - Potential Permitting Challenges: Home additions often necessitate obtaining building permits from local authorities. Delays in the approval process could impact the project timeline, causing frustration and additional costs. - Existing Home Limitations: Older homes may have structural or foundational limitations that complicate the addition process, potentially resulting in higher-than-anticipated renovation costs. Buying a New House Advantages - Move-In Ready: Purchasing a new house means immediate occupancy without the need for renovations or additional construction, ideal for those desiring a fresh start in a ready-to-live-in space. - Greater Space Options: Buying a new house provides a broad range of options in terms of size, layout, and features, allowing you to choose a home that aligns perfectly with your desired lifestyle. - Modern Amenities and Energy Efficiency: New houses often come equipped with modern amenities and energy-efficient features, leading to long-term cost savings on utility bills and maintenance. - Potential for Customization (Pre-Construction): Choosing a new house in the pre-construction phase may offer opportunities to customize certain elements, such as interior finishes and fixtures, before completion. Disadvantages - Higher Initial Costs: Purchasing a new house typically involves higher upfront costs compared to adding a home addition, considering down payments, closing costs, and potentially higher mortgage payments. - Adjustment to a New Neighborhood: Moving to a new house requires adapting to a different neighborhood, community, and local amenities, which may not be suitable for everyone, particularly those with strong ties to their current community. - Selling and Buying Challenges: The process of selling your current home and finding the perfect new house can be time-consuming, with potential delays and uncertainties. - Limited Control over Design: While new houses offer various layouts and features, you may have limited control over the design and overall structure compared to a home addition, where you can tailor every detail to your liking. In Conclusion The decision to add a home addition or buy a new house in Ontario, hinges on factors such as budget, lifestyle preferences, long-term plans, and property availability. If cost-effectiveness, customization, and sentimental value preservation are priorities, a home addition may be the preferred choice. Conversely, for those seeking a fresh start with more space and modern amenities, purchasing a new house could be the ideal solution. Thoroughly assess your needs, consult professionals, and research the local real estate market to make an informed decision, as Ontario’s dynamic real estate market offers numerous opportunities to find a home that suits your unique needs and aspirations.
When engaging a contractor for the improvement or renovation of your home, it is crucial to methodically detail various aspects within your work order or contract. These include a comprehensive description of the planned work, the specified work schedule, and the agreed-upon payment amounts and timelines. It is essential to have these specifics documented and mutually signed by both parties to ensure absolute clarity in every facet of the project. Without a written contract, you are essentially taking a risk on the project's outcome. Another equally significant component of your contract revolves around the warranty provided by your contractor. Reputable contractors offer a well-defined renovation warranty covering both materials and workmanship, explicitly outlined in the contract. Confirming its inclusion is essential. Verbal assurances, such as a contractor pledging to "address any issues that may arise," can be challenging to enforce after completion. Any hesitation from the contractor to provide such details in writing should raise suspicion. The contractor's warranty should encompass the quality of the installation or construction work, clearly specifying the coverage and duration. For instance, if issues arise within the warranty period, the contractor should promptly address and rectify them in accordance with the warranty commitment. Any reputable contractor will furnish Construction Performance Guidelines as a means of clearly outlining their commitments. Construction Performance Guidelines serve to offer advance guidance on resolving disputes between homeowners and contractors regarding defects in work or materials. These guidelines are designed to complement local Building Codes and are supported by any applicable industry association guidelines and/or standards. Importantly, they do not replace manufacturer warranties. Furthermore, the products used by the contractor in your project will come with warranties from their respective manufacturers. Typically, these warranties guarantee freedom from defects for a specified duration, provided the installation follows the manufacturer's instructions. Upon project completion, the contractor should provide you with the manufacturers' warranty documents for the project's materials—ensure you obtain these. For example, in the case of a new kitchen, the contractor's warranty covers the workmanship in construction, while separate manufacturers' warranties apply to products such as kitchen cabinets, plumbing fixtures, and flooring. Safeguarding these documents is crucial in case issues arise, allowing you to access warranty services from the manufacturers. Each product warranty delineates the coverage duration and outlines the warranty service process. Keep these documents secure for potential future use. The warranty provisions in your contract should also specify the procedures for accessing warranty services from your contractor, including relevant contact details for any necessary follow-up services.
Embarking on a journey to transform your living space is an exciting endeavor, and at Oborne Contracting, we understand the importance of making the right choice for your unique vision. In the realm of home improvement, the ultimate decision frequently revolves around two options: revitalizing your current home/space or embarking on a new construction journey. Join us as we delve into the factors that can guide you in making the best decision for realizing your dream home. Prior to initiating any home renovation project, it is imperative to acquaint yourself with the essential steps involved: 1. Evaluating Your Current Space: Before immersing yourself in the decision-making process, carefully assess your current home. Is it filled with cherished memories yet in need of a revitalizing touch, or do you yearn for a completely blank canvas? Recognizing your emotional connection to your current space can play a pivotal role in shaping your decision. 2. Assessing Your Needs and Lifestyle: Consider how your lifestyle aligns with your current home. Has your family expanded, or are you in search of a more spacious and contemporary layout? Do you need more room for activities, work, or storage? Assess how well your current layout and design meet your daily functional requirements. Do you plan to stay in your home for the long term, then perhaps incorporating features that enhance accessibility should be taken into account. Consider how the renovation can optimize your available space. Grasping your existing and prospective needs is essential in deciding whether a renovation can meet those requirements or if a new construction is the more suitable choice. 3. Define the Scope of Work: Identify the extent of your renovation project, whether it's a simple repaint or a comprehensive transformation of a space. Understanding the project scope helps in selecting the right contractor and avoiding unnecessary expenses. 4. Establish Your Budget: Determine the budget for your renovation project early on. This not only assists in defining the project scope but also aids in selecting a contractor whose services align with your financial plan. Budget plays a significant role in the decision-making process. While renovations can often be more cost-effective than new construction, it's essential to factor in potential surprises that may arise during the renovation process. A detailed discussion with our team at Oborne Contracting can help outline the financial aspects of both options. 5. Zoning and Regulations: Local zoning laws and regulations can impact your decision. Renovations might be subject to specific restrictions, while new construction provides an opportunity to design within the current zoning guidelines. Our team at Oborne Contracting can guide you through the regulatory landscape. 6. Building Permits: Assess whether your renovation requires a building permit. Typically, if the project affects a building's performance or involves an addition, a permit is needed. Understanding this requirement ensures compliance with city regulations. 7. Obtain Architectural Drawings: While not always mandatory, getting architectural drawings is recommended, even for projects not requiring a building permit. Having detailed plans reduces the margin of error and ensures the realization of your vision. 8. Estimate the Cost: Research and determine the cost of remodeling based on the size, scope, and type of renovation. Be prepared for potential cost overruns, which can range from 15-30% or more, depending on existing conditions and your chosen contractor. 9. Select a Contractor: Choose a contractor with the expertise and experience relevant to your renovation needs. Ensure they are adequately insured, have the necessary permits, and can deliver the desired results. Investing in a qualified contractor is essential for a successful renovation. 10. Maintain Communication and Review Progress: Keep open lines of communication with your contractor and construction team. Regular site visits allow you to address questions and concerns promptly, ensuring that the project stays on track. 11. Take Occupancy and Enjoy: Once the renovation is complete, take occupancy of your revitalized space and enjoy the fruits of your investment. A well-executed renovation enhances the functionality and aesthetics of your home.
