Canada updated its US travel advisory again with ominous warnings: 'You could be detained'

Canada has just updated its travel advisory for the United States once again, and the guidance now comes with even more dire warnings for Canadians travelling to the U.S.

The latest update issued by the Government of Canada on Friday includes fresh warnings about how border officials are handling arrivals, and it suggests that travellers might want to brace for extra screening.

If you've got a trip planned — especially in light of recent political tensions between the two countries — this update is worth checking out before you pack your bags.

According to the updated Canada travel advisory, posted on April 4, Canadians should now "expect scrutiny at ports of entry, including of electronic devices."

The government says U.S. authorities are stepping up their enforcement at the border and that travellers should be ready to "comply and be forthcoming in all interactions with border authorities."

The advisory warns that if you're denied entry, "you could be detained while awaiting deportation."

This new round of updates also includes a heads-up about documentation, warning that "authorities may request proof of legal status in the U.S. at any time." So even after you've made it through the border, you should be prepared to show evidence of your legal presence anytime during your stay in the country.

On top of that, the revised advisory now emphasizes that U.S. border agents have wide discretion when deciding who gets in — and that discretion is being exercised more strictly. Electronic devices like phones and laptops can be searched without reason, and agents are allowed to ask for passwords. Refusing could mean losing your device or even being denied entry altogether.

This is just the latest shift in what's been a rolling series of changes to Canada's travel warnings for the U.S. amid heightened tensions between the two countries and a U.S. crackdown on "aliens" entering the country.

Back in March, the Canadian government issued an advisory warning of a new registration rule for visitors staying more than 30 days, following an executive order by U.S. President Donald Trump. That rule takes effect this week on April 11, and anyone planning a longer trip is expected to register with the U.S. government — or risk fines and other penalties.

Meanwhile, Friday's update also included information on updated visa application rules. The advisory notes that "in February 2025, U.S. authorities made changes to some of the instructions on how to fill out visa applications," and urges Canadians to double-check the current requirements if they need a visa for any reason.

With rising friction between Ottawa and Washington — including a simmering trade feud and tense political jabs — the advisory updates seem to be part of a broader pattern. Canadian travellers, especially snowbirds and frequent cross-border visitors, are being told to stay informed and prepared, as what used to be a quick border crossing might not be so simple anymore.
