A general contractor manages the full construction project and holds the contract with the property owner. A subcontractor is hired by the GC to perform a specific trade scope, such as masonry, electrical, or plumbing. Understanding who does what prevents confusion, miscommunication, and gaps in accountability on any project.
Why Does the Distinction Between a General Contractor and Subcontractor Matter?
Property owners who do not understand the difference between these two roles often end up managing problems that should never reach them. When something goes wrong on a construction project, the first question is: who is responsible? The answer depends entirely on how the project is structured and which contracts are in place.
Stone Haven Developments operates as both a general contractor and a masonry specialist across Southwestern Ontario. Understanding how these roles interact helps property owners ask better questions, structure better contracts, and get better outcomes. Our services span project management, masonry, new construction, commercial development, and construction consulting.
What Is a General Contractor?
A general contractor (GC) is hired directly by the property owner or developer to deliver a construction project. The GC holds the prime contract, which means they are legally and financially responsible for the entire scope of work from start to finish.
The GC plans the project, hires all trades, manages the schedule, coordinates permits and inspections, controls the budget, and maintains quality and site safety standards. The property owner communicates with one professional throughout the project. Every problem, decision, and update flows through the GC.
Stone Haven Developments provides project management and full general contracting across Stratford, Kitchener, Waterloo, Guelph, Cambridge, London, Hamilton, and surrounding areas.
What Are the GC’s Legal Responsibilities?
The general contractor is responsible for compliance with the Ontario Building Code (OBC), site safety under the Occupational Health and Safety Act (OHSA), permit applications to the local municipality, and the payment of all subcontractors and suppliers under the Construction Act (Ontario). Holdback requirements under the Construction Act apply to every construction contract in Ontario over a certain threshold.
What Is a Subcontractor?
A subcontractor is a specialty trade company or individual hired by the general contractor to perform a defined portion of the construction work. Common subcontractor trades include masonry, electrical, plumbing, HVAC, framing, insulation, drywall, roofing, and flooring.
The subcontractor holds a contract with the GC, not with the property owner. They are responsible for their specific scope, their own workers, and their own workmanship within that scope. Once their trade work is complete, they leave the site. The GC remains until the full project is finished.
Does the Property Owner Deal With Subcontractors?
In a properly structured project, the property owner does not deal directly with subcontractors. All instructions, approvals, and payments flow through the GC. If a property owner starts giving instructions to subcontractors on site, it creates confusion about authority and can expose the owner to legal and financial complications.

Can a Company Be Both a General Contractor and a Subcontractor?
Yes. This is common in the construction industry, particularly for specialty trade companies with strong management capacity. A masonry company, for example, might act as a subcontractor on large commercial projects led by a major GC, while also serving as the general contractor on smaller residential and commercial projects where their trade is the primary scope.
Stone Haven Developments operates in both roles. On projects where the masonry scope is primary, Stone Haven acts as the general contractor and manages any supplementary trades required. On larger commercial builds, Stone Haven provides commercial masonry services as a qualified subcontractor alongside the project GC. This flexibility benefits clients at every project scale.
When Should a Property Owner Hire a General Contractor vs. Going Directly to a Trade?
For simple, single-trade work, hiring a specialty contractor directly can be more efficient. If you need a chimney repaired, a masonry company can handle the full scope without a GC layer.
For any project involving more than one trade, permits, structural work, or significant budget, a general contractor provides the coordination and accountability that protects the property owner. Stone Haven Developments can assess your project scope and advise on the right structure. Our chimney repair and stone restoration work can be delivered as a standalone trade scope or as part of a larger GC project depending on what the property requires.
How Does Stone Haven Developments Manage the GC and Subcontractor Relationship?
Stone Haven Developments vets every subcontractor before putting them on a site. Trade partners are selected based on workmanship quality, insurance coverage, schedule reliability, and fit with the project type. The Stone Haven standard for subcontractor performance is the same as for in-house work.
Where Stone Haven’s own masonry crews can perform the trade work directly, we do. This keeps quality control in-house and removes the coordination friction that exists when a GC delegates core work to an unfamiliar sub.

Understanding These Roles Leads to Better Projects
The general contractor vs subcontractor distinction is not just terminology. It determines who is accountable for what, how problems get resolved, how communication flows, and how legal and financial exposure is distributed across the project. Property owners who understand these roles make better hiring decisions, negotiate better contracts, and experience fewer surprises during construction.

Frequently Asked Questions
1. Who pays the subcontractor on a construction project?
The general contractor pays the subcontractor directly from the project budget. The property owner pays the GC according to the agreed payment schedule, and the GC distributes funds to subcontractors and suppliers. Ontario’s Construction Act requires a statutory holdback of 10 percent to be retained from each payment made to any contractor or subcontractor until the lien period has expired.
2. Can a subcontractor sue the property owner in Ontario?
Yes. Under Ontario’s Construction Act, subcontractors and suppliers who have not been paid can register a construction lien against the property, even if the property owner has paid the general contractor in full. This is one of the most important reasons to work with a GC who manages subcontractor payments transparently and maintains proper holdback accounts.
3. Is a subcontractor responsible for their own insurance in Ontario?
Yes. Subcontractors are responsible for their own Workplace Safety and Insurance Board (WSIB) coverage and commercial general liability insurance. A qualified general contractor verifies that all subcontractors on a project carry adequate and current insurance before they begin work. Uninsured trades create liability exposure for the property owner and the GC.
4. What happens if a subcontractor does poor quality work?
The general contractor is responsible for correcting subcontractor workmanship that does not meet the agreed standard. The GC manages that process directly, including any cost to remediate the work. The property owner should not be required to negotiate with or compensate a subcontractor for failed work. This accountability is one of the core reasons to engage a GC rather than coordinating trades independently.
5. Can I hire subcontractors directly to save money?
You can, but it transfers the GC’s coordination and accountability responsibilities to you. You become responsible for scheduling trades in sequence, managing permit applications, resolving conflicts between trades, and handling any workmanship disputes. For simple single-trade work, direct hiring is efficient. For projects involving multiple trades or permits, the coordination burden typically outweighs any savings on management fees.
6. Does Stone Haven Developments use subcontractors on its projects?
Stone Haven Developments performs masonry work in-house with its own crews. For supplementary trades on larger general contracting projects, Stone Haven works with vetted subcontractors who meet Stone Haven’s workmanship and insurance standards. All subcontractor coordination flows through Stone Haven, not through the property owner.
