Berfore the end of September 2026, Nav Canada will begin the transition to a new and updated aeronautical data processing system (ADPS), resulting in lengthy but temporary reduced capacity to process regulatory, advisory, and operations aeronautical data submissions. The most significant constraints are anticipated during the April 15, 2027 and June 10, 2027&nbsp;aeronautical information regulation and control (AIRAC) 56-day cycles. Capacity will gradually increase cycle by cycle until normal operations resume by third quarter 2027,&nbsp;with full capacity expected for the March 16, 2028&nbsp;AIRAC cycle. During the transition period regulatory and safety-critical updates will be prioritized. Non-essential changes may be deferred to later AIRAC cycles. The format, content, and scheduled release of all cyclic publications—including AIRAC, Canada Flight Supplement, Canada Air Pilot, and en route charts—will remain unchanged throughout this transition. This modernization is necessary to support evolving regulatory requirements and international data exchange standards.
