(CNN) — Freedom of movement at the world’s longest land border diminished on Wednesday when President Donald Trump announced restrictions on travel between the United States and Canada.
“We will be, by mutual consent, temporarily closing our Northern Border with Canada to non-essential traffic. Trade will not be affected. Details to follow!” Trump tweeted.
In some cases, employers, organizations and even government agencies are limiting nonessential travel.
That leaves many wondering what qualifies as nonessential travel. The answer, it turns out, is not always straightforward or even easily enforceable.

In a news briefing on March 18, a reporter asked President Trump to define nonessential travel between the United States and Canada.
“Well I think essential is medical, we have military working together, we have industry working together, and again, it’s not affecting trade, so things like that,” said President Trump. “But just leisurely ‘let’s go to a restaurant and have dinner,’ which a lot of people do … we have ended on a temporary basis.”
His reply underscored the lack of official clarity around the term.
In Ottawa on the morning of March 18, Canadian Prime Minister Justin Trudeau emphasized that both governments see supply chains as essential. “These supply chains ensure that food, fuel and lifesaving medicines reach people on both sides of the border,” Trudeau said, noting that trucking would not be affected.
“We’re telling our citizens not to visit their neighbors if they don’t absolutely have to,” said Prime Minister Trudeau at his press conference. “These measures will last in place as long as we feel they need to last.” Enforcement details are yet to be made public.
Restrictions for the rest of the world

Despite the gravity of the advisory, the US Centers for Disease Control and Prevention still leaves it up to the individual to interpret what is, and what isn’t, essential travel.
And when it comes to restricting or recommending against nonessential travel, government decisions have varied widely.
In recent days, travelers have reported being turned back at the borders of the EU when their journeys were deemed nonessential.
What is a lockdown?
New Yorkers who are 70 and over must stay inside, aside from exercising outside while alone; they’re also asked to screen their visitors’ temperatures and avoid households with multiple people.
It’s the United States’ first taste of the sweeping lockdowns that have been put in place in Italy, France and Spain.
Rules can vary by city, region or country.

In the United States, it remains to be seen whether stringent shelter-in-place orders will become more widespread.
