What Triggers a CRA Audit in Ontario?
CRA uses sophisticated data analytics and risk-scoring models to select returns for audit. Common triggers for Mississauga individuals and businesses include:
- Large or unusual deductions compared to income and industry peers
- Home office expenses claimed by T4 employees
- Consecutive years of business losses
- Vehicle expenses representing a very high percentage of income
- Significant discrepancy between reported income and lifestyle (net worth)
- Cash-intensive businesses (restaurants, contractors, retail)
- Large charitable donation claims
- Rental property losses or complex rental arrangements
- International income or foreign asset reporting (T1135)
- Tips from informants or third-party reporting discrepancies
- Industry-specific audit campaigns (CRA targets specific sectors)
- GST/HST refund claims (particularly large refunds trigger review)
The CRA Audit Process – What to Expect
- Audit Notification: CRA contacts you by letter identifying the tax years and issues under review
- Information Request: CRA lists documents required — bank statements, invoices, receipts, contracts
- Document Review: CRA examines your records (at your premises, at a CRA office, or by mail)
- Proposal Letter: CRA issues a proposal letter outlining proposed changes and reassessments
- Response Period: You have 30 days to respond to the proposal letter before CRA issues a Notice of Reassessment
- Notice of Reassessment: CRA issues the formal reassessment — triggering your 90-day objection window
- Appeal (if needed): File a Notice of Objection with CRA Appeals, then Tax Court if unresolved
At every stage, our Mississauga CRA audit representatives are by your side — ensuring you never say the wrong thing, never provide more than required, and always present your position as strongly as possible.

FAQs – CRA Audit Representation Mississauga
Do not respond to the CRA directly without professional advice. The first step is to contact a qualified tax accountant immediately. At Accountants Mississauga by BOMCAS Canada, we review the CRA audit notification, assess the scope of the audit, gather all relevant documentation, and communicate with CRA on your behalf from the very start. Acting quickly and strategically can significantly affect the outcome.
We handle all types of CRA audit reviews including: personal income tax (T1) audits, corporate income tax (T2) audits, GST/HST audits, payroll audits, net worth audits, CRA matching reviews, Requests for Information (RFI), and pre-assessment reviews. We represent both individuals and businesses in Mississauga and across Ontario.
A straightforward CRA correspondence audit may be resolved in 4–8 weeks. A complex field audit of a business can take 6–18 months or longer. Net worth audits — which CRA uses when it suspects unreported income — can take well over a year. Our Mississauga CRA audit team works efficiently to resolve your audit as quickly as possible while protecting your interests.
Yes. If CRA reassesses your tax return after an audit and you believe the reassessment is incorrect, you have the right to file a Notice of Objection with the CRA Appeals Division within 90 days of the reassessment date (one year for individuals from the filing deadline). Our Mississauga tax accountants prepare and file objections, represent you through the appeals process, and escalate to Tax Court if necessary.
A net worth audit is CRA's method of estimating unreported income by comparing changes in your personal net worth (assets minus liabilities) plus personal living expenses over several years. If CRA finds your net worth increased more than your reported income can explain, they may assess additional taxes on the "unexplained" difference. Our Mississauga CRA audit specialists have extensive experience defending net worth audit assessments.
