✈️ NAV CANADA AIC Alerts

NAV CANADA advises modifications to several Standard Terminal Arrival Routes (STARs) serving Vancouver International Airport (CYVR), effective 27 November 2025. Changes include adjusted lateral routing (wider downwind legs), revised altitude and speed constraints, and the introduction of vertical guidance to support Continuous Descent Operations (CDO) and alignment with future RNP-AR and Established on RNP (EoR) initiatives. A new CYPRESS arrival is introduced. The LIONN ARR will be NOTAM’d unauthorized until 22 January 2026, with CANUCK ARR used instead for aircraft otherwise required to file LIONN.

NAV CANADA is discontinuing the AIR 5099 Alaska Highway VNC. The 38th edition, effective 26 December 2024, will be the final publication. Information previously shown on AIR 5099 will continue to be depicted on surrounding VNC charts.

Transport Canada will establish “RPAS Restricted Airspace” under Aeronautics Act s.5.1 to prohibit/restrict remotely piloted aircraft (RPA/RPAS) operations over/near certain facilities and infrastructure where RPAS pose unacceptable safety/security/public risk. These restrictions will be published in a new DAH section, implemented via AIRAC cycles, and shown in NAV CANADA’s NAV Drone app; they will generally not appear in traditional pilot-focused aeronautical publications.

A trial of a proposed amended Preferential Runway System (PRS) at Toronto/Lester B. Pearson (CYYZ) begins 27 Feb 2020 at 0000 local and replaces the existing PRS used nightly 0000–0629 local. The amended PRS changes how preferential runways are applied by using runway pairings (arrival/departure configurations) rather than separate ranked lists.

NAV CANADA advises that all published horizontal geographical coordinates (latitude/longitude) in NAV CANADA aeronautical information/data products will be expressed in the World Geodetic System–1984 (WGS‑84) datum. This aligns with ICAO Annex 15 and Transport Canada TP 312 Ed. 5, and replaces the current AIP CANADA GEN 1.7 statement that Canada uses NAD83 (while acknowledging NAD83/WGS‑84 equivalency for aeronautical purposes).

NAV CANADA advises of temporary changes to airspace structure and special operating rules/procedures in the vicinity of Kananaskis, Alberta, associated with the Government of Canada hosting the G7 Summit on June 16–17, 2025. The measures apply June 10–17, 2025 and include airspace restrictions plus specific operating, flight planning, and authorization procedures.

NAV CANADA advises that ILS Special Authorization (SA) CAT II approaches are being introduced in Canada. These procedures can allow operations to decision heights as low as 100 ft and RVR as low as 1200 ft under certain conditions, and differ from conventional CAT II in that they may use approach/runway lighting intended for CAT I. The first Canadian ILS SA CAT II approach is planned for publication in the Canada Air Pilot on 02 Oct 2025 for Ottawa/Macdonald-Cartier Intl (CYOW) RWY 07.

This AIC provides AIRAC 2025–2026 key dates and guidance for Canadian originators submitting aeronautical information/data changes to NAV CANADA (AIS Provider), emphasizing required lead times—especially for changes affecting instrument flight procedures.

This AIC describes how Transport Canada (on behalf of the Minister of Transport) assesses threats to flight operations related to conflict zones and how related Canadian airspace notifications are issued and published (including by NOTAM when time-critical). It replaces AIC 012/2025. The provided excerpt does not include the list of current conflict-zone notifications, if any.

NAV CANADA will implement a national policy where Trigger NOTAM—used only to advise that an AIP Supplement (AIP SUP) has been published—will be issued for 14 days (rather than remaining published for the full duration of the AIP SUP, as was done when Trigger NOTAMs were introduced in Oct 2023). Trigger NOTAM contain only basic information and do not replace other NOTAM that may be required in conjunction with the AIP SUP.
