Cossack,
Yes, I've seen the term used at other airports, such as CYUL (Montreal Trudeau/Dorval).
And don't worry, Staple, the first time I saw it, it surprised me too.
Transport Canada's "Glossary for Pilots and Air Traffic Controllers" defines it this way:
- - shuttle procedure: A manoeuvre involving a descent or a climb in a pattern resembling a holding pattern. Fr: procédure de navette
Just like FFF said.
