The United States’ borders with Mexico and Canada will remain closed for non-essential travel through February 21, the Department of Homeland Security announced this week.

The land borders have largely remained closed since March at the onset of the COVID-19 pandemic. Air traffic between the countries is still permitted, but significantly curtailed due to the virus. For instance, those traveling to Canada are required to quarantine for 14 days upon arrival, and must be traveling for an essential purpose.

Air travel between the US and Mexico is continuing with more minimal interruptions.

The borders remain open for essential purposes, such as trade and for transporting goods.
