Employee vs Contractor Classification: Tax and Legal Implications in Canada
# Employee vs Contractor Classification: Tax and Legal Implications in Canada
By Bader A. Chowdry, CPA, CA, LPA | Insight Accounting CPA
Misclassifying workers as independent contractors instead of employeesor vice versais one of the most common and costly mistakes Canadian businesses make. The Canada Revenue Agency (CRA) takes worker classification seriously, and incorrect classification can result in significant penalties, back taxes, interest, and even legal liability. For businesses in Mississauga, Toronto, and across the Greater Toronto Area (GTA), understanding the difference between employees and contractors is essential for tax compliance, payroll management, and risk mitigation.
At Insight Accounting CPA in Mississauga, we help Ontario businesses navigate worker classification rules, assess their current workforce arrangements, and implement compliant hiring practices. Whether you’re a growing startup, a construction firm, or a professional services company, proper worker classification protects your business from CRA audits, employment standards claims, and unexpected tax liabilities.
In this comprehensive guide, we’ll explain the key tests used by the CRA and courts to determine worker status, the tax and legal implications of each classification, common misclassification scenarios, and best practices for compliance.

Why Worker Classification Matters
Tax Implications
Employees:
- Employer must withhold income tax, CPP, and EI at source
- Employer pays employer’s portion of CPP (matching contribution) and EI premiums (1.4x employee’s contribution)
- Employer must remit withholdings to CRA monthly or quarterly
- Employer issues T4 slips annually
Independent Contractors:
- No source deductions required
- Contractor responsible for own income tax, CPP contributions (both employee and employer portions if self-employed)
- Contractor not eligible for EI benefits
- Business issues T4A slip if payments exceed $500 annually
Legal Implications
Employees:
- Protected by Employment Standards Act (ESA) in Ontario
- Entitled to minimum wage, overtime pay, vacation pay, statutory holidays, severance (if applicable)
- Eligible for workplace safety and insurance (WSIB) coverage
- Protected by human rights legislation and wrongful dismissal laws
Independent Contractors:
- Not covered by ESA protections
- No entitlement to vacation pay, benefits, or severance
- Generally not covered by WSIB (unless deemed a “dependent contractor”)
- Subject to contract law, not employment law
Misclassifying employees as contractors exposes your business to:
- Back payment of CPP, EI, and withheld taxes, plus penalties and interest
- Employment standards claims for unpaid vacation pay, overtime, and severance
- WSIB assessments and penalties for non-coverage
- Legal liability for wrongful dismissal and human rights complaints

CRA Tests for Worker Classification
The CRA uses a multi-factor test based on common law principles established by the Supreme Court of Canada in *Sagaz Industries* and *1392644 Ontario Inc. (Connor Homes) v. Canada*. The central question is: Is the worker performing services as a person in business on their own account?
1. Control Test
Key Question: Who controls how, when, and where the work is performed?
Employee Indicators:
- Company sets work hours and location
- Company provides detailed instructions and direct supervision
- Company can discipline or terminate for poor performance
- Worker must seek permission for time off
Contractor Indicators:
- Worker sets own schedule and location
- Worker determines methods and approach to complete work
- Company specifies desired outcome, not process
- Worker can subcontract or delegate work
Example: A software developer who works remotely, sets their own hours, and uses their own equipment is more likely a contractor. A developer who works in-office during company hours under direct supervision is more likely an employee.
—
2. Tools and Equipment Test
Key Question: Who provides the tools, equipment, and materials needed to perform the work?
Employee Indicators:
- Company provides computer, phone, vehicle, tools, and supplies
- Company covers costs of equipment maintenance and upgrades
- Worker uses company email, software licenses, and systems
Contractor Indicators:
- Worker provides own tools, equipment, and vehicle
- Worker pays for maintenance, insurance, and upgrades
- Worker uses own business systems and software
Example: A construction contractor who brings their own tools, truck, and equipment is more likely an independent contractor. A construction worker who uses the company’s tools and vehicle is more likely an employee.
—
3. Financial Risk and Opportunity for Profit
Key Question: Does the worker bear financial risk and have the opportunity to profit from their activities?
Employee Indicators:
- Paid fixed salary or hourly wage regardless of profitability
- No investment in business assets or operations
- No risk of financial loss
- Expenses reimbursed by company
Contractor Indicators:
- Income depends on efficiency, client acquisition, and pricing
- Invests in equipment, marketing, and business infrastructure
- Bears risk of non-payment, project overruns, and bad debts
- Pays own expenses without reimbursement
Example: A marketing consultant who sets their own rates, invoices multiple clients, and bears the cost of client acquisition is more likely a contractor. A marketing specialist paid a fixed monthly retainer with no business risk is more likely an employee.
—
4. Integration Test (Organizational Test)
Key Question: Is the worker integrated into the business, or operating independently?
Employee Indicators:
- Work is integral to core business operations
- Worker identified as part of the team on website, business cards, and org chart
- Worker participates in company meetings, training, and events
- Worker receives employee benefits, vacation pay, and bonuses
Contractor Indicators:
- Work is project-based or supplementary to core operations
- Worker operates under their own business name and branding
- Worker provides services to multiple clients simultaneously
- No benefits, vacation pay, or employee perks
Example: A bookkeeper who works exclusively for one company, attends staff meetings, and is listed as part of the team is more likely an employee. A bookkeeper who provides services to 10 clients and advertises their own bookkeeping business is more likely a contractor.

Common Misclassification Scenarios
1. Long-Term “Contractors” with Employee Characteristics
Risk: A business hires a “contractor” full-time, sets their schedule, provides equipment, and treats them like an employeebut avoids payroll taxes and benefits by calling them a contractor.
CRA View: This is misclassification. The CRA will look at the substance of the relationship, not the contract label.
Solution: If the relationship resembles employment, classify the worker as an employee and comply with payroll obligations.
—
2. Gig Workers and On-Demand Workers
Risk: Uber drivers, delivery couriers, and gig platform workers are often classified as contractors, but courts and regulators increasingly view them as employees due to platform control and lack of entrepreneurial risk.
CRA View: Each case is fact-specific. Factors include degree of control, exclusivity, and ability to subcontract.
Solution: Seek professional advice to assess classification. In Ontario, recent cases suggest some gig workers may be deemed employees.
—
3. Incorporation Does Not Guarantee Contractor Status
Risk: A business assumes that because a worker has incorporated (e.g., operates through a personal services corporation), they are automatically a contractor.
CRA View: Incorporation is a factor, but not determinative. The CRA applies the same tests regardless of incorporation status.
Solution: Even if a worker is incorporated, assess the relationship using the control, tools, risk, and integration tests.
—
4. Dependent Contractors
Risk: A worker is technically a contractor but depends almost entirely on one client for income and is economically dependent on the relationship.
CRA View: Courts may find “dependent contractor” status, which triggers some employment protections (e.g., reasonable notice on termination) but not full employee status.
Solution: Document the contractor’s ability to work for multiple clients and avoid exclusivity clauses.
—
Best Practices for Compliance
1. Document the Relationship in Writing
Employee: Use an employment contract that specifies:
- Job title, duties, and reporting structure
- Hours, location, and supervision requirements
- Salary, benefits, vacation entitlement, and termination provisions
Contractor: Use an independent contractor agreement that specifies:
- Scope of work, deliverables, and timelines
- Payment terms (e.g., invoiced hourly or per project)
- Contractor’s responsibility for own taxes, insurance, and equipment
- Right to subcontract and work for other clients
- No entitlement to employee benefits or protections
—
2. Conduct a Classification Audit
If your business uses a mix of employees and contractors, conduct a classification audit to identify potential misclassification risks. Review:
- Degree of control over work methods and schedule
- Who provides tools, equipment, and workspace
- Payment structure (fixed salary vs. invoiced fees)
- Exclusivity and integration into the business
Work with a CPA in Mississauga or Toronto to assess each worker’s status and identify red flags.
—
3. Use the CRA’s Employee or Self-Employed Tool
The CRA offers an online tool to help businesses determine worker classification: Employee or Self-Employed?
While not binding, the tool provides useful guidance based on the Sagaz test factors.
—
4. Consider a CPP/EI Ruling
If you’re uncertain about a worker’s status, you can request a formal ruling from the CRA before a worker starts or during their engagement. The ruling process involves:
- Submitting Form CPT1 (Request for a Ruling as to the Status of a Worker Under the CPP and/or EI Act)
- Providing details about the working relationship
- Receiving a binding determination from the CRA
This protects your business from retroactive penalties if the CRA later audits the relationship.
—
Consequences of Misclassification
CRA Penalties
If the CRA determines that you misclassified employees as contractors, you may face:
- Retroactive payroll remittances: Back payment of CPP, EI, and withheld income tax for all affected workers
- Penalties: 10% of the amounts you failed to withhold, plus 20% if the CRA determines gross negligence
- Interest: Compounded daily from the date amounts were due
Example: A GTA construction company with 5 misclassified workers earning $50,000 annually for 3 years could face over $100,000 in retroactive remittances, penalties, and interest.
—
Employment Standards Act (ESA) Claims
Misclassified workers can file claims with the Ontario Ministry of Labour for unpaid:
- Vacation pay (minimum 4% of gross wages)
- Overtime pay (1.5x regular rate for hours over 44/week)
- Public holiday pay
- Termination and severance pay
—
WSIB Penalties
If a misclassified worker is injured on the job and not covered by WSIB, your business may face:
- Full liability for medical costs and lost wages
- WSIB assessments and penalties for non-compliance
—
Tax Planning Strategies
1. Structure Contractor Relationships to Maximize Deductibility
Contractors: Can deduct business expenses on their T1 (personal tax return) or T2 (corporate tax return), including:
- Home office expenses (if they work from home)
- Vehicle expenses (if they use their vehicle for business)
- Professional development, tools, and supplies
Employees: Cannot deduct most employment-related expenses (only union dues, professional dues, and specific unreimbursed expenses with a T2200 form).
—
2. Use Personal Services Corporations (PSCs) Carefully
A Personal Services Corporation (PSC) is a corporation that provides the services of a single individual who would otherwise be considered an employee. PSCs face punitive tax treatment under the Income Tax Act:
- Taxed at the highest corporate rate (no small business deduction)
- Limited deductions (only salary paid to the incorporated individual and certain direct expenses)
When to Avoid PSCs: If a worker operates through a corporation but the relationship resembles employment, the CRA may deem the corporation a PSC and apply punitive tax rates.
—
Industry-Specific Considerations
Construction
Ontario construction businesses must navigate:
- WSIB coverage requirements (contractors may need independent operator status)
- HST obligations (contractors must charge HST if revenues exceed $30,000)
- Source deduction requirements for subcontractors under Regulation 105
Best Practice: Use written subcontractor agreements, verify independent operator status, and track all payments for T5018 reporting.
—
Technology and Startups
Tech companies often engage contractors for software development, design, and marketing. Key considerations:
- Intellectual property (IP) ownership: Ensure contractor agreements specify that IP created during the engagement belongs to the company
- Non-compete and confidentiality clauses: Protect proprietary information
- Control: Avoid micromanaging contractorsspecify deliverables, not daily tasks
—
Healthcare
Physicians, dentists, and other healthcare professionals may be employees or contractors depending on:
- Degree of clinic control over work hours and patients
- Who provides medical equipment and supplies
- Whether the professional operates their own practice
Caution: Incorrect classification can affect WSIB coverage, professional liability insurance, and income splitting opportunities.

Frequently Asked Questions (FAQ)
1. Can I hire someone as a contractor to save on payroll taxes?
No. Worker classification is determined by the substance of the relationship, not the contract label. If the relationship resembles employment, the CRA will deem the worker an employee regardless of your agreement.
2. What happens if the CRA audits my worker classification?
The CRA will review the working relationship using the control, tools, risk, and integration tests. If they determine misclassification, you’ll owe retroactive payroll remittances, penalties, and interest. We recommend proactive classification reviews to avoid audits.
3. Does incorporation protect me from employee classification?
No. Even if a worker operates through a corporation, the CRA applies the same classification tests. Incorporation is a factor, but not determinative.
4. Can a worker be both an employee and a contractor for the same company?
It’s rare but possible if the worker performs distinct roles with different working arrangements. For example, an employee may also provide consulting services outside their employment duties. Document each role separately with clear contracts.
5. What is a dependent contractor?
A dependent contractor is legally a contractor but economically dependent on one client. Courts may grant dependent contractors some employment protections (e.g., reasonable notice on termination) but not full employee status.
6. How do I request a CRA ruling on worker status?
Submit Form CPT1 (Request for a Ruling) to the CRA with details about the working relationship. The CRA will issue a binding determination that protects you from future penalties.
