Two Canadian provincial premiers and the leaders of three American states are calling for the reopening of the border between the two countries.
Saskatchewan Premier Scott Moe, his Alberta counterpart Jason Kenney and the governors of North Dakota, Montana and Idaho have written to the leaders of their two countries to request the move.
The letter says the time has come for citizens to be able to cross the border freely to resume trade and tourism.
He says the current restrictions are unnecessary delays and that states and provinces are managing their COVID-19 infections.
Canada has said it will start easing American entry on August 9, while the United States has said it will wait until at least August 21.
