Nav Canada says systems operating normally after U.S. orders ground stop

OTTAWA — Nav Canada says its systems are operating normally and there is no impact on operations after the U.S. Federal Aviation Administration grounded all flights nationwide.

Nav Canada, which operates Canada’s civil air navigation system, says it continues to support the safe movement of air traffic in Canada’s airspace, including any aircraft that may be diverted.

Krista Kealey, spokesperson for the Ottawa International Airport Authority, says U.S. arrivals and departures are being affected at the airport.

She says the airport is expecting diversions, although it understands that international flights bound for the U.S. will be handled on a case-by-case basis.

Several airports, including the Montreal Trudeau International Airport and the Toronto Pearson International Airport, report that all flights to and from the United States are suspended.

The U.S. Federal Aviation Administration grounded all flights nationwide Friday afternoon, citing communications problems at regional air traffic control centres.
