Here's a question I'm trying to answer.  Here in the north, we always hear Cree flights who are cleared to fly Victor 37 from Timmins to Moosonnee.  The clearance is read back as Moosonee via Timmins Victor 37 or Moosonnee VOR via Timmins direct.  Is there a technical difference of the flight's route direction?  I know the VOR is a distance and radial from a fixed spot on the ground, just not sure if the heading to the VOR is the same as the Victor airway.  

Does this apply to flights who are cleared to smaller airports to the airport's NDB or Beacon?  Again, here we  have Bearskin flights to Kapuskasing who are cleared via Victor 5 or, to the Kaysing (K-sing) beacon via direct.

I think the procedures are a little different in Canada but generally flights in the US are cleared along published airways or radials when a preferred departure routing is available for the fix pairs.

These routings are either contained in Facility directives, Letters of Agreement (LOA) or result from NAS/ARTCC routings.

Aircraft may indeed receive a clearance direct between two fixes which are joined by an airway, (ex. cleared to Moosonee via direct Timmons direct) and the absense of a published airway (Victor 37) may be the result of requested altitude or how the flight plan was filed.
