Porter Airlines said due to Canadian quarantine laws, the continued closure of the Canada-U.S. border and the Atlantic Canada travel bubble the airline has decided to extend the service suspension to Nov. 12.

"Unfortunately, the layers of travel restrictions are serving to keep most people at home and show no signs of easing," Porter president and CEO Michael Deluce said.

Porter chief executive Michael Deluce says the ability to successfully relaunch service is directly tied to the lifting of travel restrictions.

Chief executive Michael Deluce says the ongoing uncertainty due to government travel restrictions, including border closures, is impacting the airline's ability to operate flights.

"While there are many promising signs about how COVID-19 is being contained, it is also clear that the current border restrictions, regional stay-at-home orders and limits on large gatherings will remain in place for many regions through much of May and into June," the airline said.

The airline said in a release it hopes to resume service June 1.

A judge turned down Tuesday a motion by Air Canada, Porter Airlines Inc. and 14 other carriers to freeze the traveller protections while the appeal is being dealt with.

The cancellation of Via Rail services due to blockades has left thousands of travellers in Toronto and the surrounding GTA stranded.

The Air Passenger Protection Regulations set out minimum standards for all carriers to follow and requirements to help the public understand their rights.

WestJet, Air Canada, Porter Airlines and Air Transat were all hit with penalties in August.
