Transition to ICAO NOTAM format and new NOTAM Series
In the fall of 2019, NAV CANADA will transition to the ICAO NOTAM format. As a result, NAV CANADA will distribute all Canadian domestic NOTAMs using this format and international NOTAMs under new NOTAM Series.
Runway Surface Condition (RSC) reports will remain unchanged until they are transitioned to ICAO format in the fall of 2020.
New retrieval guidelines will be provided closer to the transition date.
The changes and new NOTAM format are described in the Briefing on the Transition to ICAO NOTAM Format and new NOTAM Series.
