What is the purpose of an “engine run”?
An Aircraft Maintenance Run (or engine run) is the operation of the engine(s) of a fixed or rotary wing aircraft to conduct maintenance or correct faults.
These runs can be categorized under the following three types:
Power Run: Running an engine with the engine power setting advanced above idle power.
Idle Run: Running of an engine at idle power.
Propeller Governor Overspeed Check: A post-landing check completed from time to time by some aircraft to verify propeller safety system functionality. This run is usually under one minute.
These runs are critical to ensuring the safety of all passengers onboard aircraft arriving and departing from Billy Bishop Toronto City Airport.
What is the airport doing to prevent noise in the surrounding community caused by the airport?
PortsToronto is continually working to minimize the noise impact of the airport. Maintaining the strict noise contours (NEF 25) and aircraft noise limitations that exist today are important in that objective, as is the existing curfew that prohibits all aircraft from taking off and landing between 11 p.m. and 6:45 a.m., except for medevac services and emergencies.
The addition of the Ground Run-Up Enclosure (GRE) in 2017 represented a key new component in the airport’s Noise Mitigation Program as the acoustically and aerodynamically designed facility, constructed by Blast Deflectors Inc. (BDI), dampens the impact of ground engine run-ups that are mandated by Transport Canada following engine maintenance to ensure safety. The GRE will significantly reduce the acoustic impact of engine run-ups on the surrounding community. The enclosure effectively absorbs noise with specialized acoustic panels that line the interior of the three walls which feature vents for optimal aerodynamic performance.
In addition, PortsToronto also launched a noise monitoring website, WebTrak, in fall 2014 that allows the community to track each flight operating from the airport.
PortsToronto implemented a Noise Management Office and installed sophisticated flight tracking software in 2011 for the purposes of monitoring and identifying aircraft noise sources, and has been actively investigating and responding to public enquiries within the prescribed time limits. On the PortsToronto website all statistics are available and shared publicly.

What hours of the day are engine runs permitted to take place?
Most engine runs are scheduled to take place during daylight hours. While it is rare and avoided whenever possible, there are times when an engine run may take place after 10 p.m. on weekdays or prior to 8 a.m. on weekends. Engine runs are only completed outside of these times in urgent situations involving unforeseen and unavoidable circumstances, and Billy Bishop Airport will explore all other options before allowing an engine run to occur beyond these times.
What policies are in place to ensure engine run restrictions are followed? What are the consequences if these restrictions are violated?
PortsToronto Airport Management has Maintenance Run Procedures in place to ensure that maintenance runs are conducted not only in a safe manner but also to minimize noise impacts on the surrounding community. This procedure applies to all operators conducting maintenance runs on all airport property at Billy Bishop Toronto City Airport (BBTCA), including leased lands.
The aircraft crew and ultimately the owner/operator are responsible and liable for any and all injury to persons or damage to property resulting from their maintenance run activity.
