While the Biden administration plans to let COVID-19 public health emergency measures expire in May, proof of vaccination for non-U.S. citizens could still be in effect when crossing the border into America.

The Canadian Trucking Alliance (CTA) is urging the U.S. government to end its vaccine mandate for non-American truck drivers traveling back and forth from Canada. 

CTA officials said the border vaccine mandate affects thousands of unvaccinated truck drivers in Canada and Mexico by preventing them from entering the U.S. The United States began its vaccine border mandate for foreign drivers in January 2022.

"Once the announcement of the removal of these COVID-19 emergencies was made, there was optimism that the U.S. border vaccine restrictions would also be removed at this time," Lak Shoan, director of CTA's policy and industry awareness programs, told FreightWaves. "So far, we don't have any confirmation about whether this will occur or not."  

Last week, President Joe Biden announced the COVID-19 public health emergency will end in the U.S. on May 11. The termination of the emergency declaration will bring about policy changes and signal a new chapter in the government's pandemic response.

It's unclear if the border vaccine requirements will end May 11. The Biden administration's proclamation to rescind the COVID emergency did not mention ending the vaccine mandate for non-U.S. citizens at the border.
