Receiving a CRA audit notification is one of the most stressful events in an Ontario business owner’s or professional’s financial life. Most Canadians face a CRA audit entirely unprepared — and the wrong response to even a simple CRA review can escalate it into a full audit with reassessments, penalties, and interest. CRA audit defense in Mississauga requires a CPA who knows CRA’s audit process from the inside, understands what auditors look for, and can represent you professionally through every step. Pathak Professional Corporation provides audit defense and CRA representation for Mississauga businesses and individuals. Call 437-872-7399.
Understanding CRA Audit Types — What You’re Actually Facing
Not all CRA contacts are equal. Knowing which type of review you’re dealing with determines the appropriate response:
| CRA Audit Type | Scope | How It’s Initiated | Typical Duration |
|---|---|---|---|
| Desk review / Matching review | Single line item — usually T4/T5 slip mismatch or unverified deduction | Automatic (computer matching of slips) | 2–6 weeks with full response |
| Pre-assessment review | 1–3 specific claimed deductions before NOA is issued | CRA letter before processing is complete | 30–90 days |
| Personal T1 audit | One or more tax years — income, deductions, credits | Random selection or risk-based trigger | 3–12 months |
| Business / self-employment audit (T2125) | Business income, expenses, vehicle, home office | High expense-to-income ratio, industry targeting | 3–18 months |
| Corporate T2 audit | One or more fiscal years of corporate returns | High-value transactions, related-party dealings, large losses | 6–24 months |
| GST/HST audit | Input tax credits, sales reporting, remittances | Industry risk, large ITC claims, unreported sales signals | 3–12 months |
| Payroll audit | Employee vs. contractor classification, source deductions | Contractor complaints, T4 vs T1 discrepancies | 3–9 months |
What Triggers a CRA Audit in Mississauga?
CRA uses computerized risk-scoring systems to flag returns for review. Common audit triggers:
- High home office deductions: Claiming over 50% of home expenses as business use triggers scrutiny
- Significant vehicle expenses: Claiming 90-100% business use of a vehicle, especially without a mileage log
- Large meals and entertainment claims: Disproportionate to the type and size of business
- Consistent business losses: Reporting net losses for 3+ consecutive years on a T2125 or T2
- Cash-intensive businesses: Restaurants, contractors, retail — CRA uses industry benchmarks to flag low reported income relative to gross receipts
- GST/HST ITC claims significantly exceeding remittances: Indicating possible overclaiming of input tax credits
- T4 vs T1 mismatches: Employment income reported on a T4 but not included in the T1 return (CRA’s computers catch this automatically)
- Large charitable donation claims: Especially without donation receipts
- Real estate transactions: Property flipping, principal residence designation, non-resident withholding
- Foreign income or foreign property: T1135 reporting requirements

The CRA Audit Process — Step by Step
Understanding the audit process removes the fear of the unknown and allows you to respond strategically:
- Initial CRA contact (letter or phone call): CRA sends a letter identifying the tax year(s) under review and requesting specific documents. Never discuss your situation with a CRA auditor without professional representation — anything you say can be used to expand the audit scope
- Document request and deadline: CRA sets a deadline (typically 30 days) to provide documentation. Request an extension immediately if you need more time — CRA almost always grants extensions when asked professionally
- CPA representation authorization: File Form T1013 (Authorizing or Cancelling a Representative) to authorize Pathak Professional Corporation to communicate with CRA on your behalf. Once authorized, CRA deals exclusively with your representative
- Documentation assembly: Your CPA reviews the audit scope and assembles the exact documentation needed — organized, labeled, and reviewed for any potential issues before submission
- CRA’s review and queries: The auditor reviews your documentation and may ask follow-up questions. Your CPA responds in writing to control the narrative and avoid escalation
- Proposed adjustments (if any): CRA may propose changes — your CPA evaluates each proposed adjustment for accuracy and negotiates with the auditor to reduce or eliminate incorrect adjustments
- Notice of Reassessment (or clean close): If CRA upholds any adjustments, a Notice of Reassessment is issued. You have 90 days to file a Notice of Objection if you disagree. If CRA finds no issues, the audit closes with no changes
Why You Need Professional CRA Audit Defense in Mississauga
Self-representing in a CRA audit is one of the most common mistakes Mississauga taxpayers make:
- Scope expansion risk: Unrepresented taxpayers often provide more information than CRA requested, allowing auditors to expand into additional years or additional expense categories
- Verbal statements: CRA auditors may call you directly. Verbal statements made during these calls can be noted and used against you. A professional representative controls all communication
- Document selection: Providing the wrong documents (or too many) can inadvertently reveal issues outside the audit scope
- Negotiation inexperience: CRA auditors frequently propose adjustments that are incorrect or overstated. A CPA who knows CRA’s interpretation policies can successfully challenge these proposals
- Penalty exposure: A CPA identifies when CRA is about to impose gross negligence penalties (50% of taxes) and mounts a defense before the penalty is formally assessed
Pathak Professional Corporation’s CRA audit defense team has resolved hundreds of CRA reviews for Mississauga businesses and individuals — from simple desk reviews to full multi-year corporate audits. Call 437-872-7399.

Frequently Asked Questions
What should I do if CRA calls me directly about an audit?
If a CRA auditor calls you, be polite but provide minimal information. Say you will need to discuss with your accountant and call back. Do NOT answer questions about the specifics of your return during an unscheduled call. CRA auditors are trained interviewers — casual questions like “So you work from home — what percentage of the house do you use for business?” are designed to get verbal commitments that may be used if the percentage you claim doesn’t match your documentation. As soon as possible, contact Pathak Professional Corporation so we can file the representative authorization (T1013) and take over all communication with CRA. Call 437-872-7399 immediately.
How long does a CRA audit take?
The timeline depends significantly on audit type and how quickly documentation is provided. Desk reviews with full documentation: 2–8 weeks. Personal T1 audits: 3–12 months. Corporate T2 audits: 6–24 months. Complex cases (unreported income, fraud investigation): 2–4 years. Providing complete, organized documentation immediately when requested reduces audit timelines dramatically — CRA auditors have caseload pressures and move faster when documentation is comprehensive and professionally organized. Pathak Professional Corporation targets the fastest possible clean close for every CRA audit. Call 437-872-7399.
Can CRA audit me years after I filed?
Yes — CRA has a normal reassessment period of 3 years from the date of the original Notice of Assessment for most individual taxpayers. For CCPCs, it’s 4 years. However, there is NO time limit when CRA alleges misrepresentation due to negligence, carelessness, or fraud. CRA regularly audits taxpayers 4, 5, or even 6+ years after filing when it suspects deliberate omissions. For unreported foreign income, the reassessment period is extended. This is why maintaining tax records for a minimum of 7 years is critical — missing records from 6 years ago are nearly impossible to reconstruct, and CRA auditors may estimate your income using industry benchmarks if you can’t provide records. Pathak Professional Corporation helps Mississauga clients implement proper record retention systems. Call 437-872-7399.
What is gross negligence and how do I avoid a 50% penalty?
CRA can impose a gross negligence penalty equal to 50% of the understated tax when it determines you were grossly negligent — i.e., you knew or should have known an expense was not deductible, or you deliberately omitted income. Gross negligence is different from a simple error (which may result in interest and basic late-filing penalties but not the 50% penalty). To avoid gross negligence penalties: claim only deductions you have documentation for; disclose uncertain positions proactively; if you realize you’ve made errors, come forward through Voluntary Disclosure before CRA identifies you. Pathak Professional Corporation prepares a penalty defense narrative for every client facing potential gross negligence allegations — documenting the reasonable care taken and good faith of every position claimed.
