Ontario Payroll Calculation Guide for Tradespeople: CRA, ESA & Licensing Compliance
Accurate payroll calculation is legally mandatory for Ontario tradespeople hiring employees or incorporating as sole proprietors. Missteps risk penalties from the Canada Revenue Agency (CRA), Ministry of Labour, Immigration, and Housing (MLIHH), and disciplinary action by the Ontario College of Trades (now under Skilled Trades Ontario). This guide aligns with the Employment Standards Act (ESA), Canada Labour Code (Part III), CRA payroll requirements (RC4120), and Ontario’s Skilled Trades Regulation (O. Reg. 298/17). Whether you’re a licensed electrician, plumber, or registered home renovator, compliant payroll protects your licence and business viability.
1. Determine Employment Status Under Ontario ESA
Correctly classifying workers as employees versus independent contractors is foundational. Under Ontario’s Employment Standards Act, 2000 (ESA), factors like control, tools, chance of profit/loss, and integration determine status—not just contracts. Misclassification risks back wages, vacation pay, and ESA fines up to $10,000 per violation. The CRA uses similar but distinct criteria (RC4110); inconsistency triggers audits. Skilled Trades Ontario requires licensed contractors to ensure all employed journeypersons hold valid Certificates of Qualification—unlicensed employment violates O. Reg. 298/17. Always document work arrangements and obtain signed T2201 or T2125 forms where applicable.
2. Statutory Deductions: CRA, EI, CPP & Ontario Tax
Ontario employers must deduct federal and provincial income tax, CPP contributions (5.95% employee / 5.95% employer in 2024), and EI premiums (1.66% employee / 2.22% employer). Ontario’s provincial tax rates apply on top of federal brackets—use CRA’s TD1ON form and updated 2024 payroll deduction tables (RC4120). Employers must remit via CRA My Business Account by the 15th of the following month. Failure incurs interest (CRA prescribed rate) and penalties (up to 10% for repeated late remittances). Note: Home renovation contractors must also track HST/GST on subcontractor payments per CRA GST/HST Memorandum 10-3.
3. Ontario-Specific Requirements: Vacation Pay & Public Holiday Entitlements
Under Ontario’s ESA, employees earn 4% vacation pay (rising to 6% after 5 years) on gross wages—including commissions and non-cash benefits. Vacation time accrues at 2 weeks/year minimum; employers must schedule it within 10 months. Public holiday entitlements require averaging wages over the prior 4-week period (ESA s.26). Tradespeople using temporary staffing agencies must still comply if they direct day-to-day work. Additionally, Ontario’s Construction Lien Act (now Ontario Construction Act) mandates prompt payment timelines—delayed payroll may breach trust conditions on holdback funds. Ensure all records (pay stubs, ROEs, T4s) are retained for 6 years per CRA and ESA requirements.
4. Licensing & Compliance Implications for Licensed Trades
Skilled Trades Ontario (STO) mandates that licensed contractors maintain proper payroll documentation as part of their ‘fit and proper person’ obligations under the Ontario College of Trades Transition Act, 2021. Unpaid CPP/EI or wage violations may trigger STO investigations affecting licence renewal. Electrical Safety Authority (ESA) and Technical Standards & Safety Authority (TSSA) inspectors may request payroll records during site audits to verify qualified staff deployment. Furthermore, Ontario Building Code (OBC Div. C, Section 1.2.1.) requires licensed trades to employ only certified personnel on regulated work—payroll records substantiate compliance. Keep T4 summaries, ROEs, and WSIB clearance certificates accessible for inspection.

Do I need to charge HST on payroll I pay my employees?
No—HST does not apply to employee wages. However, if you pay subcontractors for services (e.g., drywallers), you must collect HST if you’re registered—and report it on your GST/HST return per CRA Guide RC4022. Verify subcontractor GST registration status before payment.
Can I use a flat 10% deduction for Ontario tax?
No. Ontario tax rates are progressive and depend on income level, claim codes (TD1ON), and pay frequency. Use CRA’s official 2024 payroll deduction tables (RC4120) or certified software. Flat-rate deductions risk under/over-deduction, triggering CRA reassessments and employee disputes.
