NAVAID Modernization Program

Our approach

The objective of the NAVAID Modernization Program (NMP) is to define a network of ground-based navigation aids to supplement a fully-implemented, satellite-based ANS, through the largest navigation realignment undertaken in Canada to date.

We are taking a phased approach to ensure it is completed in the safest and most efficient manner. To find out which NAVAIDs have been decommissioned and which ones are scheduled, see the lists below.

Given the project’s size, complexity and long implementation timeline, NAV CANADA is committed to ongoing coordination with impacted users based on the change schedule and its implications. The time frame for each phase will be based on an Aeronautical Information Regulation and Control (AIRAC) cycle with a submission and review every five months. The completion date of the project is planned for May 2024.
