YELLOWKNIFE - A northern air carrier behind the popular TV show "Ice Pilots" has been grounded.

Transport Canada says it has suspended the operating licence for Yellowknife's Buffalo Airways over what it calls the carrier's poor safety record.

The suspension took effect Tuesday morning.

Buffalo Airways, with its fleet of Second World War era DC-3 airplanes, was the subject of a long-running reality TV show on the History Canada channel.

"Ice Pilots" ran for six seasons until last December.

A spokesman from the carrier could not immediately be reached for comment.
