DHS commences pilot project to collect DNA from certain travellers

The Department of Homeland Security (DHS) recently announced a pilot project to collect DNA samples from certain travellers, which commenced on January 6, 2020.
This announcement has prompted questions from Canadians (and other foreign nationals), who are concerned that they may be required to provide a sample of their DNA when travelling to the United States. Although privacy advocates are concerned about this mandatory collection of DNA, the pilot project, as it presently stands, may not be a significant departure from current practices.
