While it's no real secret that Canada has been more cautious than the United States when it comes to travel during COVID-19, a look at the skies reveals the true contrast of each country's individual approach.

Flightradar24 is an app that allows users to view the planes that are travelling above them at any given moment. 

An image taken from the app on Wednesday, July 29 at 6.20 p.m.(ET) shows heavy flight traffic south of the border. 

Flightradar24 shows the difference in the volume of flights between the U.S. and Canada.

The density of planes flying in the south is a clear demonstration of the U.S.'s more relaxed attitude toward travel. 

Since the beginning of the pandemic, Canada has been running a restricted portion of flights related to essential travel only.

Air traffic north of the border appears to be heaviest near Toronto's airports, followed by Calgary, Vancouver and Montreal. 

The Government of Canada has advised the public to avoid all non-essential travel outside of Canada until further notice. 

Travel to Canada is also currently being restricted for all foreign nationals coming from any country. 

The restrictions currently prohibit foreign nationals, including U.S. nationals, from entering Canada for non-essential travel. 

The government's Emergency Order under the Quarantine Act requires persons entering Canada by air, sea or land to isolate for 14 days in order to limit the spread of COVID-19.

The U.S. government does not have similar national measures in place at present but some states do require mandatory 14-day self-quarantines for travellers.
