U.S. government won't say why it allows Canadians to fly to U.S. despite border closure

It's a quirky rule that has confounded many people: whilethe Canada-U.S. land border is closedto non-essential traffic due to the COVID-19 pandemic, Canadians can still fly to the United States for leisure travel.

"It's like having your front door lockedbut your back door wide open," said U.S. immigration lawyer Len Saunders, whose office sits close to the Canadian border in Blaine, Wash.

"It just doesn't make sense."

To add to the confusion, theflying rule isn't reciprocal: Canada bars American travellersfrom entering by any mode of transport, unless they get a special exemption.

Saunders said he has been bombarded with calls from Canadians during the border closureinquiring about flying to the U.S.

"People are still calling me saying, 'I just want to clarify that this is OK. And why can I fly, but I can't drive?'"

CBC News asked the U.S. government that same question, but didn't get a response.

Foreign relations expertEdward Alden suggests the reason why Canadians can still fly to the U.S.may be rooted in the fact that, compared to Canada, the U.S. hasless stringent travel restrictions for air passengers.

"The measures in the United States are just across the board far more relaxed," said Alden, a professor of U.S.-Canada economic relations at Western Washington University in Bellingham, Wash.

"[It's] certainly one of the reasons we have higher [COVID-19] case numbers."

'I could have walked'

To help stop the spread of COVID-19, Canada and the U.S. agreed in late March to close their shared land border to non-essential travel.

Since then, many Canadians have flown to the U.S, after discovering that it's still allowed.

But theflying exemption has also sparked bewilderment.

Birgit Heinbach lives in Surrey, B.C., just seven kilometres from her American husband's home across the border in Blaine, Wash.

Because she can currently only fly to the U.S., Heinbach said it took seven hours and two flights from Vancouver to Seattle and then Seattle to Bellingham to get to her husband's home when she visited him in July.

"The whole thing was ridiculous," she said. "I could have walked in my own little shoes in 45 minutes to my husband's house."

Canadian snowbirdTamara Carmichael lives in a non-winterized mobile home in Leduc, Alta., in the summer. Her winter home sits in an RV park in Yuma, Ariz.

Although Carmichael can still fly to the U.S. this winter, she said that's not an option because she needs her truck to get around in Yuma, and can't afford the fee upwards of $1,500 to ship it.

She argues the U.S. flying exemption is nonsensicalbecause driving is a safer way to travel during the pandemic.

"Sticking everybody on an airplane is not a solution," said Carmichael. "You're packed into a tin can with a bunch of other people."

According to a U.S. government document, it sanctioned the land border closure because "non-essential travel between the United States and Canada poses additional risk of [COVID-19] transmission."

CBC News asked several U.S. government departments and agencies why the government still welcomes Canadian air passengers. The Department of Transportation and Customs and Border Protection (CBP) referred CBC to the Department of Homeland Security's main office. That office and the Centers for Disease Control and Prevention referred CBC to CBP.

No one provided an answer, despite repeated inquiries.

Experts offer theories

Alden theorizesthat Canada which has strict travel restrictions prompted the land border closure, and that while the U.S. agreed, it had no desire to take it further.

Canada has restricted most foreigners from entering the country by any mode of travel during the pandemic. But foreigners can still fly to the U.S. as long as they haven't visited Brazil, China, Iran, Ireland, the U.K. or 26 European countries in the Schengen Area 14 days prior.

Canada was never added to that no-fly list. Neither was Mexico, even though Mexico and the U.S. have also agreed to close their shared land border to non-essential travel.

"Generally, the United States has a much looser regime in terms of trying to keep out travellers," said Alden. "They don't see casual travellers asmuch of a threat, because they're worried about drugs and illegal migrants and terrorism."

U.S. President Donald Trump returned to the White House still infected with the coronavirus and removed his mask on the balcony before going inside. He then tweeted a video of himself telling Americans not to be afraid of coronavirus or let it take over their lives.

Alden also said that the U.S. may have reasoned it would be too cumbersome for the country's airlines to weed out the non-essential travellers if the country expanded its land border bans to air passengers.

"If you were going to make distinctions between essential and non-essential travellers, the airlines were going to have to be involved in some way."

LawyerSaunders said he spoke this week with a senior U.S. CBP official who believes the U.S. still welcomes Canadian air passengers due to pressure from U.S.airlines to keep flights in operation.

"He said the airline industries would have lobbied hard when they were drafting this border closure," said Saunders.

But the actual reason why Canadians can fly to the U.S. remains a mystery until and unlessits government offersan explanation.
