What Canadians Should Know If They’re Travelling Now

Where do I have to quarantine within Canada?

Non‑residents arriving in Manitoba, Yukon, Northwest Territories and Nova Scotia have to self‑isolate for 14 days (unless, in Nova Scotia’s case, they’re coming from elsewhere in Atlantic Canada). Non‑residents heading to Nunavut must quarantine for two weeks outside of the territory – in Ottawa, Winnipeg, Edmonton or Yellowknife – and have their travel approved by the chief public health officer. Residents from outside Atlantic Canada travelling to Newfoundland and Labrador, New Brunswick and P.E.I will also have to quarantine – if, that is, they’re permitted entry, which only happens in extenuating family and medical circumstances.

What happened to the Atlantic bubble?

Regrettably, the bubble has burst. In early July, the four Atlantic provinces agreed to let residents travel freely within their borders without quarantining first. But in late November, with Covid‑19 cases rising, Newfoundland and Labrador and P.E.I. pulled out of the arrangement, suspending non‑essential travel and requiring self‑isolation.

What should I do if I’m returning home from outside of Canada?

You need to get acquainted with the ArriveCAN app. The Government of Canada requires everyone entering the country to download ArriveCAN before their flight and provide travel and contact information, a self‑assessment for Covid‑19 symptoms and a 14‑day quarantine plan (which includes where you’ll be staying, how many people will be there, and whether you can have food and necessities delivered). After you land, you need to confirm you’re in isolation and complete daily self‑assessments until the two weeks are up. (If you don’t have or can’t use a smart phone, alternative arrangements can be made.)

Okay: how likely am I to catch Covid on a plane, really?

“The overall sense is that airplanes are not as important a means of spreading Covid‑19,” says Dr. Susy Hota, medical director for infection prevention and control at University Health Network in Toronto. The virus primarily spreads through respiratory droplets and smaller aerosols generated when an infected person coughs, sneezes or talks. Planes have high‑efficiency filters and ventilation systems designed to scoop up these particles, cycle air out of the cabin and filter it at a much higher rate than indoor spaces like offices and restaurants. In fact, a U.S. Defense Department study conducted this summer found that a plane’s air‑filtration system removed the virus 15 times faster than in a typical home.

Masks also play an important role in blocking your respiratory droplets from getting out and, to a lesser extent, other people’s droplets from getting in – which is why in‑flight masking is now mandatory. In September, infectious disease experts from the University of Alabama at Birmingham looked at five flights, each at least eight hours long, with rigid masking policies. A total of 58 passengers tested positive for Covid‑19 on arrival, but when the other 1,500‑plus passengers were swabbed two weeks later, none of them appear to have been infected.

When it comes to Covid‑19, no activity is 100 percent safe. Mask effectiveness can vary: Health Canada says three layers are best, though you can make your own filter to slip between two layers. You probably want to skip the in‑flight snack, beer or anything else that means removing your mask. Definitely keep the sanitizer handy. “But there’s enough evidence out there to suggest planes are probably safer than people initially thought,” Hota says. “Initially, people said, oh no, how is it different than a cruise ship? It’s actually quite different from a cruise ship.”

And remember to take steps to keep yourself safe off the plane, as well. “I think the biggest risk within airports is the issue of congregation,” Hota says. Maintain physical distance in customs lines and baggage claims, apply hand sanitizer before and after using any high‑touch screens, and keep that mask firmly in place.

What should I do when I land somewhere outside of Canada?

Restrictions vary from country to country; consulting the Canadian government’s travel advisories can help. At least 120 countries require travellers to present proof of a negative Covid‑19 test before arrival, generally within 72 hours of the date of departure. Depending on where you live and the testing criteria, though, this might be tricky: provinces like Ontario, Alberta and Nova Scotia won’t test individuals who haven’t been exposed to Covid or aren’t exhibiting symptoms.

Let’s say I get a rapid test at an airport – do I still need to quarantine for 14 days?

Airports that offer rapid tests on arrival – like in Istanbul, Munich and Havana – generally mean a shortened quarantine for people who test negative, whether that’s a few days or even a few hours. Most airports use a throat swab or a saliva swab to detect the presence of the virus. But there are some important caveats, Hota says. One is that these point‑of‑care tests aren’t the most sensitive, catching only high amounts of the virus – which means that minimally symptomatic or asymptomatic people will be missed. Another is that “your test result reflects your status at the very moment you’re tested, but we’re dealing with a virus that has an incubation period of up to 14 days,” she says. “So you might test negative at day two of being exposed but still be transmitting to other people.”

Are there better tests in the works?

Yup. In September, McMaster Health Labs, in partnership with Air Canada and the Greater Toronto Airports Authority, began testing roughly 16,000 international travellers at Pearson Airport. Each volunteer self‑administered a high‑sensitivity oral and nasal polymerase chain reaction (PCR) test, “which is the gold standard throughout Canada,” says Dr. Marek Smieja, scientific director at McMaster Health Labs. The self‑collected PCR swabs were then repeated, in quarantine, at day 7 and day 14, and robotic‑based laboratory testing turned results around in under 24 hours.

The good news: 99 percent of travellers tested negative for Covid‑19, and the vast majority of positive cases were caught on arrival. A quarter of cases were identified at day 7, but fewer than one in 1,000 people tested positive on day 14. “That’s the second good news, because the argument for shortening quarantine is that there are very few or no cases after day 7,” Smieja says. The study will deliver its final results in January, but “we like to think we’ve demonstrated the feasibility of testing large numbers of people more efficiently than anything we can currently offer in my clinical laboratory,” Smieja says. “I can see in the future there could be a similar regimen for international and domestic travellers.”
