Every year, the Canada Revenue Agency (CRA) selects a portion of filed tax returns for closer review. While some audits are triggered by random selection, the majority are anything but random. The CRA actively concentrates its audit resources on specific areas it has identified as high-risk, and those priorities shift from year to year.

In 2026, the CRA is more equipped than ever to find discrepancies. The agency has significantly advanced data analytics and automated risk assessment tools to cross-reference taxpayer information from employers, financial institutions, government databases, and third-party platforms. In short, the CRA knows more than it ever has before.

For Ontario taxpayers, understanding where the CRA is focusing its attention this tax season is one of the most practical steps you can take toward filing with confidence.

Here are four areas that tax professionals say are squarely in the CRA’s crosshairs this year.

1. Short-Term Rental Income

The real estate sector has long attracted CRA scrutiny, but short-term rentals are receiving particular attention in 2026.

A growing number of provinces and municipalities across Canada have introduced restrictions on short-term rental platforms such as Airbnb and VRBO in an effort to return properties to long-term housing stock. The CRA is increasingly using non-compliance with local rules as a basis for denying expense deductions.

Specifically, the CRA denies expense deductions for short-term rental properties that do not comply with local municipal or provincial regulations. This means that if your rental operation is not properly registered or licensed under local rules, you may be required to report all of the income you earned, but you will not be permitted to deduct the expenses associated with running it.

Beyond the compliance issue, the CRA is also looking closely at whether short-term rental income is being reported at all, and whether it is being properly categorized.

What this means for you: If you earn income from a short-term rental, ensure your property is compliant with all local registration and licensing requirements. Keep detailed records of all income and related expenses, and make sure the income is reported accurately on your return.

2. Cryptocurrency and Digital Asset Transactions

With more Canadians investing in and transacting with cryptocurrency, digital assets have become a major focus of CRA enforcement efforts.

Canada’s tax rules are clear: cryptocurrency is treated as a commodity, not a currency. That means virtually every transaction involving crypto has potential tax consequences, whether you are selling, trading, converting, or even using it to make a purchase. Capital gains or losses must be reported whenever you dispose of cryptocurrency, and the CRA expects Canadians to keep detailed transaction records.

What has changed in 2026 is the CRA’s ability to obtain this information. The agency has been increasing its efforts to collect data on digital currency transactions directly from third parties, including cryptocurrency exchanges operating in Canada. This significantly narrows the gap between what taxpayers report and what the CRA can verify independently.

What this means for you: Do not assume that cryptocurrency transactions are invisible to the CRA. If you have bought, sold, traded, or used cryptocurrency in the past year, those transactions need to be accounted for. The records you are required to keep include dates, transaction values in Canadian dollars at the time of each transaction, and the gain or loss on each disposal.

3. Gig Economy and Platform-Based Income

If you earned income in 2025 through platforms such as Uber, DoorDash, Airbnb, Etsy, Fiverr, or any other gig or marketplace platform, that income is taxable, and the CRA expects it to be reported.

The obligation to declare income from self-employment and online platforms has always existed under Canadian tax law. What has changed is the CRA’s visibility into this income. Under rules that have been expanding in recent years, digital platforms are increasingly required to share information about payments made to Canadian sellers and service providers directly with the CRA.

The result is that unreported gig income is much easier to identify than it once was. The CRA can now compare what a platform reports paying you against what you reported on your return.

What this means for you: If you have side income from any platform, even a small amount, it should be included in your tax return. Self-employed individuals must also be aware of their obligations to collect and remit HST once their income exceeds the $30,000 threshold, and to report business expenses accurately and with proper documentation.

4. Real Estate Transactions and Principal Residence Claims

Property-related tax issues continue to be a top area of CRA focus, particularly around two specific situations: the flipping of newly built properties and the misuse of the principal residence exemption.

The CRA is paying close attention to cases where a taxpayer builds a new home and then sells it shortly after, while claiming the property as their principal residence to shelter the gain from tax. The principal residence exemption is a legitimate and valuable part of Canadian tax law, but it is designed for properties that a taxpayer genuinely occupies as their home, not properties that are bought or built with the primary intention of resale.

Since 2023, Canada has also had an anti-flipping rule in place: residential properties sold within 12 months of acquisition are generally treated as business income rather than capital gains, with no access to the principal residence exemption.

In addition to the flipping issue, the CRA has strengthened oversight of real estate transactions generally, using land registry data, property assessment records, and other sources to identify patterns that may indicate unreported income or improperly claimed exemptions.

What this means for you: If you sold a property in 2025, ensure that you have properly reported the transaction on your return. Even if the gain is fully sheltered by the principal residence exemption, CRA now requires the sale to be reported. Failing to report the disposition, even if you owe no tax, can result in penalties.

Why CRA Audits Are More Data-Driven Than Ever

It is worth understanding the broader context for why these four areas are drawing attention now.

The CRA’s enforcement capabilities have expanded substantially in recent years. The agency’s 2025-2026 departmental plan outlines a continued commitment to deploying advanced data analytics, AI-based tools, and third-party data sharing to identify non-compliance. Revenue mismatches, unusual expense patterns, and inconsistencies between what a taxpayer reports and what third parties report are now flagged automatically before a human auditor ever reviews the file.

Proposed legislative changes would also give the CRA additional tools to compel taxpayers to respond to information requests during audits, with potential daily penalties for non-compliance.

The takeaway is straightforward: the CRA has more tools, more, and more enforcement resources than ever before. Filing accurately and keeping thorough records is not optional, it is the foundation of staying on the right side of a review.
