Nav Canada warns to expect flight delays at Vancouver International Airport

The agency that provides air traffic control for Canada’s airports is warning travellers at Vancouver’s airport of flight delays over what it says are “resource constraints.”Nav Canada says in a social media post that passengers need to check the status of their flights with their airlines before they head to Vancouver International Airport.The agency said earlier this year that there was a severe shortage of air traffic controllers who help manage 18 million square kilometres of Canadian airspace.
