Contractor vs Subcontractor: What's the Difference?
When planning a home renovation or repair project in Canada, one of the first things homeowners need to understand is the difference between a contractor and a subcontractor. These terms sound similar but have distinct differences that can significantly affect your project timeline, budget, and legal responsibilities in Ontario, Alberta, British Columbia, or wherever you are renovating. Knowing who is responsible for what protects you if something goes wrong.
Understanding the Basic Difference
At its core, the difference between a contractor and a subcontractor comes down to client relationships and project responsibility. A contractor (typically called a general contractor or prime contractor) is the professional you hire directly. They're responsible for the entire project, manage the budget, coordinate timelines, and handle most of the client communication. A subcontractor is a specialized tradesperson hired by the contractor to complete specific portions of the work.
Think of it this way: if you're building a house, the general contractor is like the project manager who oversees everything, while subcontractors are the electricians, plumbers, roofers, and other specialists who handle their specific trades. The contractor manages the subcontractors; you manage the contractor.
The General Contractor: Your Project Leader
A general contractor (GC) is a licensed professional who takes on the responsibility of completing an entire project or a significant portion of it. In Canada, general contractors must be properly licensed depending on the province - in Ontario, for example, they may need to be registered with ServiceOntario, while British Columbia requires licensing through the BC Safety Authority.
Key responsibilities of a general contractor include:
- Obtaining necessary permits and ensuring code compliance
- Creating detailed project timelines and budgets
- Hiring and managing subcontractors
- Ensuring work quality and safety standards
- Managing project finances and invoicing
- Serving as your primary point of contact
- Handling warranty claims and follow-up work
In Canada, general contractor costs vary by region and project complexity. For a kitchen renovation in Toronto or Vancouver, you might expect to pay $150–$300 per hour for a contractor's time, with many charging a percentage markup (typically 10–20%) on materials and subcontractor costs. A complete bathroom renovation might cost $15,000–$35,000 CAD depending on the scope and location.
One significant advantage of hiring a general contractor is accountability. You have one person or company responsible for the entire project, making it easier to resolve disputes or issues that arise during construction.
The Subcontractor: The Skilled Specialist
Subcontractors are licensed tradespeople who specialize in specific areas of construction or renovation. Common types of subcontractors include electricians, plumbers, carpenters, roofers, HVAC technicians, and tile installers. In provinces like Alberta and Quebec, these trades are often regulated through apprenticeship programs and licensing boards.
Key characteristics of subcontractors:
- Specialized expertise in their specific trade
- Usually work on multiple projects simultaneously
- Hired by contractors, not directly by homeowners (typically)
- Responsible only for their portion of the work
- Often have lower overhead costs than general contractors
Subcontractor rates in Canada typically range from $50–$150+ per hour depending on the trade and experience level. For example, a licensed electrician in Canada might charge $85–$150 per hour, while a plumber could charge $80–$120 per hour. These rates often include materials markup.
When Should You Hire a General Contractor?
A general contractor is your best choice for:
- Large projects involving multiple trades (full home renovations, new additions, major basement finishes)
- Projects requiring permits and code compliance oversight
- Complex coordination where timing between trades is critical
- Structural work that requires professional project management
- Warranty protection and legal liability coverage
For example, if you're planning a $50,000+ renovation in BC or Ontario that requires permits, working with a licensed general contractor protects you legally and ensures the work meets building codes.
When Can You Hire Subcontractors Directly?
In some cases, homeowners can hire subcontractors directly, which may save money:
- Single-trade projects (electrical work, plumbing repairs, HVAC maintenance)
- Small repairs that don't require extensive coordination
- When you have project management skills and time to oversee work
- Projects under $5,000–$10,000 in most Canadian markets
However, hiring subcontractors directly comes with responsibilities. You become the "contractor" in the eyes of the law, meaning you may need to obtain permits, verify insurance and licensing, manage payments, and handle any disputes that arise. Many homeowners find this approach more stressful and time-consuming than initially expected.
Regional Differences Across Canada
Contractor and subcontractor regulations vary by province. In Ontario, the Home Warranty Plan requires certain renovations to be covered by warranty, which typically requires working with licensed contractors. British Columbia has different requirements for residential contractors depending on project value. Alberta and Quebec have their own apprenticeship and licensing frameworks for trades.
Before hiring anyone, research the specific requirements in your province to ensure you're working with properly qualified and insured professionals.
Questions to Ask Before Hiring
Whether you're considering a general contractor or subcontractor, always ask:
- Are you properly licensed and insured in [your province]?
- Can you provide references from recent projects?
- What's included in your quote (materials, labour, permits)?
- What's your timeline and payment schedule?
- What warranty do you offer on your work?
- How do you handle changes or issues during the project?
Frequently Asked Questions
Do I need to pay GST/HST to both contractors and subcontractors?
Yes, if the contractor or subcontractor is GST/HST registered, they'll charge applicable tax on their invoice. In Canada, most renovation work is subject to GST (5%) or HST (13–15% depending on province). Some small businesses may not be registered if their revenue is below $30,000 annually, but this is rare in the home services industry.
What's the difference in liability between hiring a contractor vs. a subcontractor directly?
When you hire a general contractor, they typically carry liability insurance that covers their work and their subcontractors. When you hire a subcontractor directly, you assume more liability. Ensure any tradesperson you hire carries Workers' Compensation coverage and liability insurance before work begins.
Can a subcontractor become a general contractor?
Yes. Many subcontractors expand their businesses to take on general contracting roles. However, they still need to meet the licensing and bonding requirements in their province. This transition often involves getting additional training, certifications, and business insurance.
How much will I save by hiring subcontractors directly instead of a general contractor?
You might save 10–20% by hiring subcontractors directly and eliminating the contractor's markup. However, this savings can quickly disappear if you encounter coordination problems, delays, or quality issues. For a $40,000 project, direct hiring might save $4,000–$8,000, but the hidden costs of project management often offset these savings.
