Several Canadian airports I've been at have a FSS on the field. Their
facility looks like a tower cab, but not up on a tower, and they are the
ones you talk to (you say "St. Catherines Radio" instead of "St.
Catherines Traffic" or they get upset with you), but they tell you the
wind an altimeter settings, tell you if anybody else is in the pattern,
but they don't clear you for anything.

You only talk to Flight Service Centre or Flight Service Station at airports
with a Mandatory Frequency. Airports that have a MF require that you
contact the appropriate Remote Aerodrome Advisory Service on the MF. That
will be a an FSS or FIC who will then advise traffic and field conditions.
Subsequent calls are sort of made to local traffic and the RAAS. (ie.
London Radio N-XXX is turning final Muskoka".) Note that the RAAS / FSS
isn't usually anywhere near the field.
