Key moments
On October 18, 2025, Kevin Larson, a 68-year-old retired nuclear power plant employee from Canada, was held for three hours at the Blue Water Bridge border crossing in Sarnia, Ontario. During this time, he was compelled to provide a DNA sample by U.S. Customs and Border Protection (CBP) officials, a situation that has sparked outrage and concern over privacy rights.
Larson was attempting to enter the United States to attend a rally in Port Huron, Michigan, when he was denied entry due to what officials described as “insufficient evidence” for his intended purpose. Despite possessing a valid Canadian passport, Larson was told that he could face charges if he refused to comply with the DNA collection request, which he ultimately did to avoid a longer-term ban from entering the U.S.
The incident has drawn attention to a directive issued in 2025, which mandates that CBP collects DNA samples from individuals arrested on federal charges. This directive has raised questions about the legal and ethical implications of such practices, particularly in cases where individuals are not formally charged with any crime.
U.S. Representative Debbie Dingell expressed her outrage over the incident, stating, “This kind of hostile and arbitrary treatment at the border could further damage one of our most important bilateral relationships.” She highlighted that there was no evidence of any pending warrants or criminal history against Larson, emphasizing the lack of justification for the DNA request.
In a statement, Larson expressed his discomfort with the situation, saying, “I said, ‘No, I consider that a privacy thing. I’m not going to do it.'” He described feeling rattled by the experience and indicated that he complied with the request primarily to avoid complications that could arise from refusing.
Dingell, along with fellow lawmaker Jamie Raskin, has since sent a letter to CBP seeking clarification on the legal basis for taking Larson’s DNA. As of now, they have not received any responses regarding the incident, leaving many questions unanswered.
In light of this experience, Larson has stated that he plans to avoid future trips to the U.S. until there is a change in the administration, reflecting a growing concern among citizens regarding the treatment of travelers at the border. The relationship between the U.S. and Canada has been strained in recent years, particularly due to policies enacted during the Trump administration, which have raised issues related to border security and civil rights.
Details remain unconfirmed regarding the broader implications of this incident on U.S.-Canada relations and the enforcement of border policies. However, the situation underscores the ongoing debate over privacy rights and the extent of government authority in the context of border security.
