Canada, US and Mexico extend border restrictions to July 21.

The U.S., Canada and Mexico have agreed to extend their agreements to keep their shared borders closed to non-essential travel to July 21 during the coronavirus pandemic

Canadian Prime Minister Justin Trudeau said Tuesday's agreement extends the closure by another 30 days. The restrictions were announced on March 18 and were extended in April and May.

"This is a decision that will protect people on both sides of the border as we continue to fight COVID-19,” Trudeau said.

Many Canadians fear a reopening. The novel coronavirus has sickened more than 2 million people in the U.S. and killed more than 115,000, according to Johns Hopkins University. It has sickened more than 99,000 and killed 8,175 in Canada.

Americans who are returning to the U.S. and Canadians who are returning to Canada are exempted from the border closure. Immediate family members of Canadians are also allowed entry into Canada, but must quarantine for 14 days.

Canada sends 75% of its exports to the U.S. and about 18% of American exports go to Canada. The U.S.-Canada border is world’s longest between two nations.

“Canada is open to it so long as it is OK by the local health authorities,” he said.
