The Canadian government has warned travelers, particularly retirees heading to the U.S., about increased border scrutiny and a new mandatory registration rule. Starting in April 2025, those staying over 30 days must file with the Department of Homeland Security or face severe penalties.

The April 2025 DHS Alien Registration mandate

Beginning in April 2025, the United States government will require Canadians who spend 30 days or more in the U.S. to register with the Department of Homeland Security using an Alien Registration Form. According to the report, failure to complete this registration or provide proof of it upon entry could lead to fines or imprisonment.. While the registration itself is free, the process may involve indirect costs and requires significant advance planning to avoid border delays.

This new requirement adds a layer of bureaucracy to a journey once defined by ease. U.S. customs agents already possess the authority to search electronic devices and phones at border crossings, and this new registration rule suggests a shift toward more stringent tracking of Canadian nationals residing temporarily in the States.

The 183-day threshold and Form 8840

Tax obligations for Canadians in the U.S. are governed by a complex "substantial presence" formula. As the report says, snowbirds who spend more than 182 days in the U.S., based on a three-year rolling average, can be classified and taxed as U .S. citizens. To avoid this, those who fall under the 183-day count but are deemed "substantially present" must file Form 8840, known as the Closer Connection Exemption Statement, to prove their primary ties remain in Canada.

The risks of miscalculating these dates are high. Kim Moody,CEO of Moodys Tax in Calgary, warns that Canadians with outdated tax filings or those who overstay their immigration status risk being labeled "illegal aliens." Such a designation can lead to a permanent ban from entering the United States, transforming a seasonal vacation into a lifelong legal exile.

Privacy Commissioner warnings over 2016 data sharing

A 2014 information-sharing agreement between the Canada Revenue Agency (CRA) and the U.S. Internal Revenue Service (IRS) has created a pipeline of sensitive data. This agreement allows the IRS to access personal details including the location of permanent homes,business activities, and family members. In 2016, Canada's Privacy Commissioner expressed concern that this sharing could extend to highly personal data, such as religious affiliations, political leanings, and voting records.

The Privacy Commissioner recommended that the CRA notify individuals when their data is handed over to the IRS. However, exemptions under the Privacy Act often allow these disclosures to happen without explicit consent. Currently, Canadians must contact the CRA diretly to discover what specific information has been shared with U.S. authorities.

The 2008 real estate crash and the US$1.10 exchange rate

The current climate of scrutiny is rooted in economic shifts from over a decade ago. Kim Moody of Moodys Tax suggests the information-sharing pact was likely triggered by a surge in Canadians purchasing U.S. rental properties following the 2008 real estate crash. During that era, high oil prices drove the Canadian dollar to a peak of over US$1.10, significantly increasing the buying power of Canadians in the U.S . market.

This trend of property ownership persists today. A 2023 report from snowbirdadvisor.ca indicates that approximately half of all Canadian snowbirds in the U.S. own real estate. This ownership creates a permanent financial footprint that the IRS can easily track,making the "substantial presence" test even more critical for property owners.

Why snowbird numbers dropped by 20 per cent

The Canadian Snowbird Association estimates that while one million retirees typically travel south, that number has recently declined by 15 to 20 per cent. The Association attributes this drop to a perception that the United States has become "hostile" toward Canadians. This sentiment is likely fueled by the combination of aggressive tax audits and the looming April 2025 registration requirement.

Despite these warnings, several critical details remain unclear. The source does not specify the exact "indirect costs" associated with the DHS registration, nor does it clarify if there are exemptions for those with specific visa types. Furthermore, while the report mentions the Privacy Commissioner's 2016 concerns, it remains unverified whether the CRA has since implemented the recommended notification system for impacted citizens.
