Flights were delayed at Alberta airports because of a software glitch.
Some flights were delayed more than two hours on Saturday morning when traffic control officials had to begin manually inputting some flight path data.
The problem was fixed and flight times returned to normal by Saturday afternoon.
Ron Singer, spokesman with Nav Canada, said an investigation is ongoing.
“The problem did occur (this morning) while we were installing a software upgrade to our automatic flight data management system,” he said.
“We have reverted to our backup system.”
However, Singer said the technical problems, while inconvenient, did not affect passenger safety.
