Proposal of new scenarios for operations during restricted operating hours - Citizen consultation


ADM is launching a citizen consultation on the proposal of new scenarios for operations during restricted operating hours at YUL.

Reducing operations outside of operating hours is a priority for ADM. Over the past two years, ADM has been working on the development of new operating scenarios based on certified noise levels rather than aircraft weight. This is one of the key actions of the Soundscape Action Plan.

Montréal-Trudeau is the first airport in North America to propose this type of scenario. This forward-thinking initiative, based on international best practices, aims to provide more flexibility to certified quieter aircraft while reducing the noise impact on surrounding communities. This revision takes into account the technological evolution of the industry and the improvement of the acoustic performance of aircraft.

Your participation is crucial in shaping these solutions and ensuring a sustainable future for the airport and the surrounding community.

As part of this consultation, ADM held an open house event on May 9, from 2:30 p.m. to 7 p.m., in the conference rooms on the 2nd floor of the YUL Montréal-Trudeau terminal. See the Soundscape Newsletter for more information on this event.


Air Movements and Passengers

The significant increase in passenger numbers does not translate into an increase in the number of air movements. Over the past 20 years, air movements have remained relatively stable despite a continued increase in passenger numbers. This is due to a higher load factor and the use of larger capacity aircraft.



2011 vs 2023:



This effective management underscores our commitment to responsible airport operations, maximizing efficiency while reducing environmental impact.


Restricted Hours of Operation - Present Situation




  • YUL operates 24/7: light aircraft (less than 45,000 kg) can take off and land at any time.
  • Night restrictions – aircraft over 45,000 kg: no take-off between midnight and 7 a.m. and no landing between 1 a.m. and 7 a.m., with some exceptions.
  • ADM can grant exemptions for medical emergencies, delays beyond the carrier's control, adverse weather conditions and for some scheduled flights.
  • Strict policy to minimize exemptions.
  • These measures are essential to reduce the noise impact at night while preserving the operational capacity of the airport.


Restricted Hours of Operation - Proposed New Scenarios

Basic Principles

Period without scheduled flights: Introduction of a time slot with no scheduled flight activities. No flights except for emergencies and for one-off exemptions (e.g. medical emergencies, weather conditions, mechanical checks).

Summer/winter scenarios: Adaptation to seasonal variations, taking advantage of conditions with windows closed in winter for better sound insulation.

Restriction of pre-approved exemptions: The new scenarios limit the pre-approved exemption process. Currently, some flights have pre-approved exemptions. For example, some flights making a double rotation to a southern destination in winter have a scheduled departure between 6 a.m. and 7 a.m.

Categorization of aircraft according to their noise footprint: Implementation of restrictions based on the certified noise level of aircraft according to ICAO (International Civil Aviation Organization) standards.


Aircraft Categories

Classification of aircraft into five categories: Based on ICAO Certified Noise Level (EPNdB), with specific aircraft types for each category.  



*Assigned categories will be determined based on the certification of each aircraft based on its characteristics and configuration.


Rigorous Noise Measurement: Performed at specific points during takeoff and approach and adjusted for the tone and duration of recorded sounds, expressed in EPNdB for increased accuracy compared to standard dB(A) measurements.  

For more information on the ICAO certification process, see Q4 of the Soundscape FAQs.


Proposed New Restricted Hours of Operation  




Hours of operation based on noise footprint: The noisiest aircraft (Category 5) are already restricted at YUL, the restriction period will be increased to between 11 p.m. and 8 a.m. Then, restrictions apply depending on the season and the categories of aircraft. For example, Category 4 aircraft are restricted in the summer between 11 p.m. and 7 a.m. and in the winter between midnight and 7 a.m. Finally, the most efficient aircraft can operate from 6 a.m. to 1 a.m.

Period with no scheduled flights: From 1 a.m. to 6 a.m., no scheduled operations are permitted except in cases of emergency, or due to delays beyond the carrier's control. This includes general aviation flights.

Gradual start of morning operations: Starting at 6 a.m. for categories 1 to 3, at 7 a.m. for category 4 and at 8 a.m. for category 5 aircraft.


Next Steps

Following the consultation process with citizens and airport aviation stakeholders, Transport Canada will be seized of the file in order to approve the scenarios that will then be published in the Canada Air Pilot (CAP). The new scenarios could be implemented from 2026.



The scenarios that are proposed today are built on technological advances, designed to accommodate a generation of acoustically efficient aircraft.

With a forward-looking perspective, we aim to:

  1. Welcome the quietest aircraft at YUL.
  2. Reduce greenhouse gas emissions, taking an active part in the fight against climate change.
  3. Establish a period without scheduled flights.
  4. Adapt our operations to seasonal variations with distinct summer and winter scenarios, reflecting changing needs throughout the year.

The consultation closed on June 15, 2024. We thank participants for their contribution.



Master Plans 2023-2043



1.  Why is ADM Aéroports de Montréal holding a public consultation?

ADM Aéroports de Montréal, the airport authority for the Greater Montréal area, is responsible for the management, operation and development of YUL Montréal-Trudeau International Airport and YMX International Aerocity of Mirabel under a lease signed with Transport Canada in 1992 that expires in 2072. As a not-for-profit, community-based corporation, ADM values public engagement. The views of citizens and airport users will help create a long-term strategy that will serve as a framework for future planning and development activities, while maintaining the flexibility needed to respond to changing conditions in our industry.


2.  What are the stages of the public consultation process?

ADM will roll out this public consultation process in four phases over the next few years. Here are the main stages:

  1. Public consultation specifically focused on the future of YUL via an online platform available now;
  2. Publication of a reflection document on the major development challenges facing YUL Montréal-Trudeau International Airport and YMX International Aerocity of Mirabel, and stakeholder consultations for each site;
  3. Development of two preliminary Master Plans and validating them with stakeholders;
  4. Submission of final Master Plans and approval by the relevant authorities.


3. What is a Master Plan and what are its objectives?

A Master Plan sets out the airport's long-term vision and major development directions. A number of development and modernization projects are derived from these major directions. Its objectives include:
