Have a doctor's note ready if you're trying to get on a plane without a face covering. Wearing masks at airports in Canada is mandatory and now the government has closed a loophole that allowed people to not wear them. You could be denied boarding because of this.\nTransport Canada issued an interim order on August 7 about requirements when it comes to air travel throughout the country because of COVID-19.\nIt closed a loophole that allowed people to get around the mandatory face-covering rule at airports.\nWith this order, a person doesn't have to wear a mask if there is a medical reason as to why they can't do so.\nHowever, people now have to actually prove that.\nThey'll only be allowed to not wear a mask if they can show a medical certificate that confirms they aren't able to wear one because of a medical reason.\nSo people basically have to provide a doctor's note at Canadian airports if they want to travel without covering their faces.\nInfants, people who can't remove their mask without assistance and others are exempt from the rule along with those who can prove there's a medical reason to not wear one.\nView this post on Instagram The new YVR health and safety program, YVR TAKEcare, reflects the latest health, safety and cleaning measures outlined by government agencies and health industry experts.

While we miss seeing all the different aircraft and liveries, we miss our community more. Being a healthy airport is about more than installing plexiglass and cleaning more frequently - it's about staying connected with our community throughout this time of change.
