Land borders were shut in March in response to the outbreak and have been repeatedly extended since then, with the most recent closure extension scheduled to lapse on Oct. 21. The closure doesn't affect air travel or apply to people providing essential services.
"The U.S. and Mexican governments further recognize critical services such as food, fuel, healthcare and life-saving medicines must reach people on both sides of the border every day. Essential travel must therefore continue unimpeded during this time."
Canada’s public safety minister said that the earliest the border will reopen is now Nov. 21.
The land border closure extension comes as parts of the United States experience surges in CCP virus cases. On Oct. 16, health officials reported more than 70,000 new infections, making it the highest single-day increase in the United States since late July.
"In each of our countries, we are encouraging people to exercise caution by avoiding unnecessary contact with others," DHS said on its website. "This collaborative and reciprocal measure is an extension of that prudent approach," the agency said, referring to land border closures.
