PILOT PROGRAM NOW MORE THAN A MONTH OLD

More than a month ago, the Alberta and Canadian governments entered into a pilot program aimed at testing an alternative to the 14-day quarantine requirement for Canadian citizens returning from abroad.

Under the agreement, which came into force on Nov. 2, COVID-19 testing is being conducted on all Canadians returning to the country at the Coutts, Alta. land crossing and at Calgary International Airport.

All passengers who are part of the pilot program are ordered to go into self-isolation for 14 days immediately upon arrival. If the tests come back negative, those passengers are allowed to leave quarantine provided they commit to a second test at least six or seven days after arrival.

Health Canada says the pilot project's aim is to gather important information needed to guide its strategies to combat the COVID-19 pandemic.

"(It) will ensure changes to public health measures are informed by strong scientific evidence," it wrote in a statement to CTV News.

CTV News has reached out to the Alberta government and WestJet Airlines for an update on the pilot project.
