CRA Worker Classification Audit — Montreal CPA Firm Near You: Employee vs Contractor Defense

A CRA Worker Classification Audit is designed to determine whether individuals performing work for your business are truly independent contractors or should legally be treated as employees. This classification affects CPP/EI, QPP/QPIP, HSF, payroll taxes, and even director liability.
Mackisen CPA Montreal represents employers during CRA and Revenu Québec worker-status audits, providing evidence-based defense, proper documentation, and preventive compliance strategies that protect your business and directors from costly reclassifications.


Legal Foundation

Law: Income Tax Act ss.5 and 9 (employment vs. business income), Canada Pension Plan s.21, Employment Insurance Act s.82, Tax Administration Act (Québec) arts.40–44.
Jurisprudence: Wiebe Door Services Ltd. v. MNR (1986 FCA) — established CRA’s “fourfold test”: control, ownership of tools, chance of profit, and risk of loss.

Learning insight: CRA doesn’t care about job titles — it cares about how control, risk, and independence function in real life. Mackisen CPA ensures your documentation reflects that reality.


Why CRA and ARQ Conduct Worker-Status Audits

These audits prevent payroll under-remittance and ensure workers receive proper CPP, EI, QPP, and QPIP coverage. CRA selects cases based on data inconsistencies or whistleblower tips.

Common triggers include:

  • Repeated T4A payments to the same individuals.

  • Contractors performing duties identical to employees.

  • Lack of business registration or GST/QST numbers for contractors.

  • Anonymous complaints from ex-employees or competitors.

  • Payroll totals inconsistent with business volume.

Learning insight: CRA uses data to question dependence — Mackisen CPA uses facts to prove independence.


CRA Worker-Status Audit Process

  1. Notice Issued: CRA sends an audit letter identifying the years and workers under review.

  2. Document Request: CRA requests contracts, invoices, and payment details for each contractor.

  3. Worker Interviews: Auditors may contact individuals directly to confirm control and supervision level.

  4. Status Evaluation: CRA applies the Wiebe Door and Sagaz tests to assess employment indicators.

  5. Decision and Assessment: CRA may reclassify contractors as employees and issue payroll adjustments.

Learning insight: A worker audit can redefine your relationships — unless your CPA defines them first.


Mackisen CPA’s Audit Defense Strategy

  1. Contract Review: Assess every contract for independence clauses, risk distribution, and control structure.

  2. Evidence Compilation: Prepare files demonstrating business independence (multiple clients, invoices, tools).

  3. Classification Report: Conduct internal Wiebe Door and Québec civil-law tests before CRA does.

  4. CRA Representation: Handle all communication, submissions, and responses professionally.

  5. Post-Audit Protection: Implement compliant contract templates and tracking systems.

Learning insight: CRA respects preparation. Mackisen CPA ensures every relationship in your business passes the independence test.


Common CRA Reclassification Consequences

  • Retroactive payroll taxes for up to 4 years (CPP/EI/QPP/QPIP).

  • Interest and penalties under ITA s.227.1 or LAF s.40.

  • Personal liability for directors.

  • Disallowed GST/QST input tax credits.

  • Disruption of contractor relationships and financial planning.

Learning insight: A single reclassification can ripple through your entire tax system — Mackisen CPA prevents that wave before it starts.


Real-World Case Success

  • A Québec construction firm avoided $185,000 in reassessments after Mackisen CPA proved subcontractors owned equipment and bore risk.

  • A marketing agency defended 17 contractor relationships when we provided valid GST/QST registrations and multi-client proof.

  • A tech company cleared a $68,000 payroll adjustment when our CPA team demonstrated contractual and operational independence.

Learning insight: CRA reclassifies when it sees dependency — Mackisen CPA ensures it sees distinction.
