Ontario Payroll Calculation Guide for Tradespeople: CRA, ESA & Licensing Compliance
Accurate payroll calculation is critical for Ontario tradespeople—whether you’re a sole proprietor hiring your first apprentice or a licensed plumbing contractor managing five employees. Missteps can trigger CRA penalties, ESA fines, or jeopardize your Certificate of Qualification under the Ontario College of Trades (now Skilled Trades Ontario). This guide walks you through legally mandated calculations using current federal and provincial regulations—including the Canada Labour Code (Part III), Ontario’s Employment Standards Act (ESA), CRA payroll guides (T4001), and Skilled Trades Ontario licensing rules.
1. Determine Employment Status & Licensing Requirements
Under Ontario law, you must first classify workers correctly: employee vs. independent contractor. The CRA and ESA use control, ownership of tools, chance of profit/loss, and integration tests—not just contract language. Licensed tradespeople (e.g., electricians under ESA Reg. 285/01) must ensure apprentices are registered with Skilled Trades Ontario and paid at least 75% of journeyperson wages per ESA s.23.2. Unlicensed handymen performing restricted work (e.g., electrical in dwellings) violate the Ontario Electrical Safety Code and may face prosecution under the Ontario Building Code Div. B 26-100. Always verify Certificate of Qualification status via Skilled Trades Ontario’s public registry before payroll setup.
2. Calculate Gross Wages & Statutory Deductions
Start with gross pay: hourly rate × hours worked (capped at 44 hrs/week unless ESA exemption applies). Ontario’s 2024 minimum wage is $16.55/hour (ESA s.23); construction trades often exceed this via collective agreements or journeyperson rates. Statutory deductions include CPP (5.95% on earnings between $3,500–$68,500), EI (1.66% on max $63,200), and federal/provincial income tax (use CRA’s 2024 TD1ON forms). For subcontractors, issue T4A slips—not T4—if they’re unincorporated but meet CRA’s business criteria. Remember: Ontario Health Premium (OHP) applies if annual taxable income exceeds $20,000—calculated separately, not deducted at source.
3. Apply Ontario-Specific Statutory Entitlements
Ontario’s ESA mandates vacation pay (4% of gross wages for <5 years’ service; 6% after), public holiday pay (average regular wages × 1.5 for eligible days), and overtime (1.5× regular rate after 44 hours/week). Tradespeople must track hours daily—even for remote or site-based work—as ESA s.24 requires written records for 3 years. If employing apprentices, confirm their wage scale aligns with Skilled Trades Ontario’s Apprenticeship Training Standards (O. Reg. 438/17). Also, note: Ontario’s ‘Construction Industry Wage Act’ doesn’t apply to most residential trades—but ESA still governs all provincially regulated employers. Failure to remit vacation pay within 30 days of termination triggers ESA s.11(2) penalties.
4. Remit, Report & Maintain Compliance Records
Remit CPP, EI, and income tax to CRA by the 15th of the following month (or weekly/bi-weekly if remitter type is ‘accelerated’—common for contractors with >$25K annual remittances). File T4/T4A slips and summaries by February 28 annually. Keep payroll records for 6 years per CRA s.241 and ESA s.24—include names, SINs, hours, wages, deductions, and proof of Skilled Trades Ontario registration for apprentices. Under Ontario’s Building Code Act, s.11, inspectors may request payroll documentation during safety audits to verify licensed personnel are performing regulated work. Use CRA’s My Business Account and Ontario’s HR Portal for real-time compliance checks and ESA self-assessments.

Do I need to charge HST on payroll I pay myself as a sole proprietor?
No. As a sole proprietor, you don’t pay yourself a salary—you withdraw funds as owner’s draw. HST applies only to taxable supplies (e.g., services to clients), not internal compensation. However, if incorporated, shareholder salaries require full CRA payroll deductions.
Can I pay my apprentice below minimum wage in Ontario?
Only if registered with Skilled Trades Ontario and paid per the approved apprenticeship wage scale (e.g., 75% of journeyperson rate in Year 1). Unregistered trainees must receive at least $16.55/hour per ESA s.23—no exceptions for trades.
