Ottawa, July 15 (TIWN) Canada and the United States have agreed to keep the border between the two countries closed to non-essential travel until August 21, CTV News reported.

The agreement, which has to be reviewed each month, was set to expire on July 21. It's now being renewed for the fourth time since the border closed to non-essential traffic on March 21.

News of the extension was first reported by Reuters.

The extension comes after Prime Minister Justin Trudeau and U.S. President Donald Trump spoke on the phone Monday about a range of issues that included the border closure.
