Canada and the U.S. will extend for 30 days the restrictions that closed their shared border to most travelers, Prime Minister Justin Trudeau said.

Separately, the White House said President Donald Trump spoke with his Mexican counterpart about the need for continued border restrictions on the southern U.S. frontier.

Canada and the U.S. agreed to close the border to non-essential travelers in March. Saturday’s agreement extends the measures to May 20. It has the same terms as before and allows essential goods and services to move between countries, Trudeau said at a news conference in Ottawa

The measures will keep people on both sides of the border safe, Trudeau said.

During the press conference, Trudeau also said Canada has received two plane shipments of personal protective equipment, which countries across the world are struggling to obtain due to increased demand. Last week, Trump reversed an earlier announcement that he would not allow the export of N95 protective masks, carving out exemptions for Canada and other jurisdictions.

Trump spoke Friday with President Andres Manuel Lopez Obrador of Mexico about the Covid-19 pandemic and other matters, White House spokesman Judd Deere said in a readout.

The pair discussed the need to maintain restrictions on land border crossings for non-essential reasons “while ensuring cross-border activities that are critical to commerce, health security, supply security, and other essential industries remain unimpeded,” Deere said.

Trump during the call offered additional resources to Mexico’s government to support its health care system. The president tweeted on Saturday that he had a “very gold” conversation with AMLO.

Trump said at a White House news conference on Saturday that he had offered Mexico U.S.-made ventilators to combat its own Covid-19 outbreak.

“They desperately, in Mexico, need ventilators,” Trump said. “We’re building, now, thousands a week.”

In his own readout, sent Friday, AMLO said Trump had offered 1,000 ventilators by the end of the month, as well as other intensive-care medical equipemtn.

The U.S. has over 700,000 confirmed coronavirus cases and more than 37,000 deaths, far more than its Nafta neighbors. Cases in Canada are approaching 33,000 with over 1,300 deaths. Confirmed cases in Mexico are over 6,870 with over 500 fatalities.
