to provide the service in a particular case is not subject to question, nor need it
be communicated to the pilot.
Within radar coverage, a radar-derived traffic information, navigation or position
information service may be provided to VFR flights. Pilots wishing to use radar services
must be in direct VHF communications with ATC and be equipped with
a serviceable transponder. Flights using the service will not be allocated a specific
transponder code except when the ATC intends to provide an ongoing service.

CLASS E AIRSPACE
Pilots of VFR flights receiving a Radar Information Service (RIS) in Class E airspace will
be provided with information about radar observed traffic. However, due to the nature
and type of radar coverage, not all aircraft will be observed on radar. Consequently,
traffic information provided by ATC may be incomplete.
Pilots must comply with the see-and-avoid requirements of CAR163A.
On initial contact, pilots must advise position, level and intentions and advise the radar
service required. ATC will respond by identifying the aircraft, and notifying the pilot
that the aircraft has been “IDENTIFIED” prior to the commencement of traffic
information, position information, or navigational assistance. ATC may also assign a
specific transponder code prior to, or during the provision of, radar services. ATC must
be advised of any attention to change track or level.
When ATC is unable to provide radar services, the pilot will be advised
“RADAR SERVICE NOT AVAILABLE”. Requests for emergency assistance should be
prefixed by “MAYDAY” (three times) or “PAN PAN” (three times), and will receive
priority.
Radar services may be terminated at any time by the controller or by pilot request.
When services are terminated, ATC will advise "RADAR SERVICES TERMINATED”
(see Note 2 below). If a specific transponder code has not been allocated, ATC will
advise "SQUAWK CODE 1200”.
Note 1:Navigational guidance is advisory in nature and the responsibility
for the safe operation of the aircraft remains with the pilot.
Terrain clearance, aircraft-to-aircraft separation, and obtaining
clearances into controlled airspace remain pilot responsibilities.
Note 2:When radar services to VFR flights are terminated, pilots should
monitor an ATS frequency appropriate to their area of operation.
