NAV CANADA has discontinued AIR 5099 Alaska Highway VNC. The chart will be permanently removed from availability on March 19, 2026. Existing aeronautical and topographic information previously shown on AIR 5099 will continue to be depicted on other VNCs.
NAV CANADA aeronautical study recommends increasing the dimensions of the Saskatoon (CYXE) Control Zone to a 7 NM radius with a cut-out to exclude Richter Field Aerodrome (CRF5), and designating the control zone as Class C. The modified control zone description will be published in the Designated Airspace Handbook (TP 1820E).
NAV CANADA assessed airspace near Foremost, AB and is changing the activation period (designation time) for Class F restricted areas CYR 234, 235, and 236. The Designated Airspace Handbook (TP 1820E) operating procedures will also explicitly state that access shall be granted to aircraft conducting aerial application for agricultural purposes upon request.
NAV CANADA AIC highlights that civilian specialty air combat training (SACT)—aggressive manoeuvring/close proximity operations—cannot be conducted safely in shared airspace, and notes restrictions put in place under Aeronautics Act s.5.1 effective 19 Dec 2025. The excerpt provided includes definitions used for the notice (built-up, sparsely settled, remote areas; SACT operations; tactical navigation training; close formation). Specific geographic/airspace restrictions and conditions are not included in the provided excerpt.
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.
