On March 14, 2026, Tania Warner, a Canadian citizen holding a valid U.S. work visa, was detained along with her seven-year-old daughter Ayla at an interior immigration checkpoint near Sarita, Texas, while driving home from a baby shower. Despite presenting proper documentation — including her work visa, Canadian passport, and proof of her five-year residence in the United States — Warner and her daughter were taken into custody by CBP officers at the checkpoint and subsequently transferred to ICE.
The pair were moved to the South Texas Family Residential Center in Dilley, Texas, one of ICE's largest family detention facilities. Warner's husband, a U.S. citizen, learned of the detention hours later and immediately contacted immigration attorneys and Canadian consular officials. Ayla, who had been diagnosed with autism spectrum disorder, was described by her father as "terrified and unable to understand what was happening," with the disruption in her routine causing severe distress.
The case drew intense media coverage in Canada, where it became a symbol of the indiscriminate nature of the Trump administration's immigration enforcement apparatus. Canadian Prime Minister Mark Carney raised the case directly with the State Department, and the Canadian consul in Houston visited the Dilley facility. Immigration attorneys representing Warner said that CBP officers at the Sarita checkpoint had questioned the validity of her work visa and placed her in custody pending "verification" — a process that, under normal circumstances, could be resolved in minutes through database checks.
The detention highlighted the expanding reach of interior immigration checkpoints, where even individuals with valid immigration status faced the risk of prolonged custody. Warner's case was one of several involving Canadian, European, and other allied-nation citizens detained at checkpoints or during routine ICE operations despite holding valid visas or legal permanent resident status — incidents that immigrant rights organizations described as evidence that the enforcement system had become so aggressive that it was consuming its own legal framework.
