Update to the previous Gander OCR Procedure update.

Gander (CDQX) FIR Domestic ATC will issue oceanic route clearances and amendments via VHF voice communications instead of CPDLC loadable Route Clearance uplink messaging before an aircraft reaches its Oceanic Entry Point (OEP). This is expected to continue through May 31, 2026, according to AIP Canada Supplement 130/25. Refer to NOTAMS and other relevant documents for updates.

Other OCR procedures, including Oceanic flight planning, RCL submission requirements and timing, and CPDLC route conformance monitoring, will continue unchanged. Route changes issued to aircraft after passing the OEP will continue to be issued via CPDLC or HF communications.

For voice RCL requests or issues with an RCL rejection message, pilots should contact ATC on the assigned (current) control frequency.
