NAV Canada response to M.P. John Carmichael

NAV CANADA to Carmichael MP Jan 17-2013

Letter to Minister Lebel – No more night flights please

The attached letter is in regards to residents concerned for their quiet enjoyment of their homes, neighbourhoods. This relates to sleep interruption caused by increased business demands of Pearson airport and the flight pattern changes as of Feb. 9th, affecting a number of wards in Toronto.

If you are interested in objecting to the increased night flights proposed by GTAA, this letter should be printed, signed, and mailed to Minister Lebel. Air Traffic and Night Flights_Letter_March15 SR finalThank you for you support.

NAV Canada changes affecting residents

To all residents living in Ward 22 and 25, specifically ratepayer associations for:
Davisville Village, Sherwood Park, Bennington Heights, Leaside, Don Mills, Hogg’s Hollow, ACREA

On Feb. 9, 2012, NAV Canada made changes to their arrivals flight path over our neighbourhoods. The north edge of the previous flight path was flying over Lawrence Park. It has now moved south by 1.8km. The net result that has been observed over Davisville Village is a dramatic increase in arrivals traffic in the evenings till approx. 12:30 a.m. In addition, this is causing increased noise over our homes and neighbourhoods.

In addition, NAV Canada has implemented a new arrivals corridor over North Toronto for preferential runways – used between 12:30 a.m. and 6:30 a.m. Aircraft fly over North Toronto during these night time hours at altitudes between 6000 and 9000 feet ASL (above sea level). This corridor routes these arrivals aircraft towards south Mississauga before turning east to land at Pearson airport. Preferential runways are only used when wind direction and strength permits. In the winter time, historically, winds are at greater strength and do not always allow for optimal usage of these runways, therefore causing arrivals to land in a westerly direction and bringing the flights lower over North Toronto at 3000 feet ASL (minimum).

Lastly, Pearson airport is pursuing a major hub strategy, which coincides with a night flight budget increase filing to the Minister of Transport. This will have additional negative effects on night time sleep and disturbances.

I urge you to complain to your local councillor and make them aware of this impact.  In addition, you may write directly to the following individuals to voice your concerns:

GTAA – Toby Lennox – VP Public Affairs:
NAV Canada – Sam Ghobrial:
Minister of Transport – The Honourable Denis Lebel:

This letter was mailed to Chuck Strahl, Minister of Transport in early October 2010. Copies were sent to local and federal politicians, and local rate payer groups.

Lawrence Park traffic study

GTAA traffic study for Lawrence Park and Davisville Village

GTAA aviation sound level readings – Arrivals

The following sound level readings were taken on the evening of March 31st, at two locations in North Toronto.
It took at least one year of complaints to get GTAA to come out to these neighbourhoods and take sound- level readings with portable instrumentation.

GTAA sound level readings – arrivals

Location #1 (Davisville Village) sound readings were taken from after 9:00 p.m. till appox. 10:00 p.m. Due to traffic noise from Mt. Pleasant Rd. and the flight patterns, these readings were inconclusive to demonstrate the noise from arrival aircraft.
Location #2 (Mt. Pleasant and Lawrence area) had sound level readins taken from approx. 10:00 p.m. till 11:00 p.m. All readings were taken by GTAA Noise Mgmt. office staff, using a dBA scale meter. The only signigicant factor, aside from the excessive traffic in the evening over the resident’s home, is that the loudest reading for an arrival (A320) was 65 dBA at 3600 feet ASL. The lowest ambient noise reading during this monitoring period was 50 dBA.

Therefore, it has been proved the worst case is a 15dBA delta – a noticeable difference experienced by the residents while attempting to retire for the evening.

GTAA has advised they have taken readings for departure traffic in Location #1 – Davisville Village. These results have not been produced at time of writing. A note to Tim Kendall (GTAA Mgr. Airside Operations – Noise Mgmt. office) will be sent for follow-up.

GTAA expansion history

Dr. Lloyd McCoomb was very involved in the planning and expansion of Pearson airport prior to his appointment as CEO and president of GTAA.

While his planning has been beneficial for the surrounding airport business and passenger experience as compared to prior to airport expansion, these same plans obviously have had an impact on our neighbourhoods with aviation traffic.
See attached:

Feb 1, 2007 – appointed President and CEO
2006 – Pearson airport handled in excess of 30 million passengers
1996 – joined GTAA
1994 – Airport General Manager
1991 -1992 – he managed a major project for the planning, preliminary design and
                     environmental assessment for three new runways at Toronto Pearson
1989 – Director General, Safety and Technical Services
1986 – Transport Canada, Director General, Airports Marketing
1983 – Transport Canada: Director, Statistics and Forecasts

Before these career positions, he worked for American Airlines as Airport General Manager.

Business Excellence Online article text from an interview with Dr. Lloyd McCoomb:

Moving onto environmental stewardship and sustainability, which are listed in the company’s mission statement, I ask McCoomb how an airport can hope to be environmentally friendly given the current publicity about emissions and the popularity of carbon offsetting schemes, not to mention noise. “Every way imaginable,” he says. “First we have to recognize right up front that we have a significant impact on the community around us. Don’t deny it. Airport noise is a huge issue and deserves our undivided attention, and it gets it.”

Toronto Pearson has a program that monitors aircraft noise. “The airport has a radar system that tracks the aircraft, and we have standard departure procedures that we insist the aircrew follow. They must obtain a certain elevation before they start to turn, and we have monitoring stations that measure the noise and we track it continuously; Transport Canada has punitive fines for cowboys who play fast and loose with our noise rules.” There is also a noise management committee for the community to participate in decision making that impacts their noise. “We’ve secured from that a wonderful agreement with the surrounding communities in the airport operating area,” says McCoomb.

1. Mr. McCoomb has no idea what impact he has caused the residents of Lawrence
     Park, South Eglinton, Sherwood Park, and the York Mills/Leslie areas. He does
     not personally experience the noise impacts or the impact to these quiet
     communities that contain vibrant neighbourhoods and many urban
     parks/forests/green space.
2. If there is undivided attention from the GTAA, why does the CENAC committee
     appear toothless and ineffective when dealing with the impacts of constant flight
     traffic over our neighbourhoods – every 30-90 seconds! The traffic prevents
     residents from going to sleep at night, wakes us up in the middle of the night
     –  thank you FedEx with your B727 hush-kit equipped noisy jets
3. Why has it taken in excess of over one year to get FedEx to change their aircraft
     to quieter B757-manufactured  Chapter-3. By the time there is complete fleet
     conversion, the time line is probably closer to 3-plus years or even longer!
4. The operating agreement mentioned certainly didn’t include the City of Toronto
     for noisy night-flight departure traffic or residents being prevented from sleeping
     in on Sunday mornings past 6:30 a.m. when residents experience over 16 flights
      in approx. 30 mins. when NAV Canada is using runway 06 for east-bound
5. If GTAA was serious about noise monitoring within their operating area, there would
     have been additional monitoring stations placed in the respective neighbourhoods
     that experience the noisy departure traffic and the high-volume arrivals traffic.
6. Residents in the above neighbourhoods have indicated a noticeable increase in
     Pearson aviation traffic in the past 1-3 yrs. In addition, residents of East York
     are now noticing increased commercial aviation traffic to/from Pearson airport,
     since 2009.
The noise impact continues.

GTAA-Area Of Responsibility

GTAA area of responsibility is 10 nautical miles. This radius extends to slightly eastward, beyond Lawrence Park Ratepayer Association boundary and South Eglinton Residents and Ratepayer Association boundary
– to Rumsey Rd. in Leaside.

Research indicates that departure aircraft frm runway 06 transit this area at speeds of approx. 250 kts (knots) – expected to be a lower/quieter power setting, and at approx. 9 to 10 nautical miles from Pearson airport, pilots set the aircraft flight director to climb power, a higher/noisier power setting.


Noise tracking log – Davisville Village

This log GTAA-log-Davisville Village is from a single resident in Davisville Village.
As can be seen, there are numerous impacts over this person’s home; evenings, weekend mornings, and sometimes the middle of the night.
The resident was not aware they would purchase their home in a flight
path. GTAA advises no change in procedure, but will admit to change in volume. All times in the log are expressed in 24-hr format.

Lawrence Park residents have noticed increased Pearson traffic
over their neighbourhood in the past 1-3 years. Sherwood Park
residents experience high volumes of aircraft over their neighbourhood
as well, especially noticed on Easter Monday 2010 in the afternoon,
children playing in Sherwood Park and a bombardment of jet traffic overhead!
Flight arrival/departure frequency can be as often as every 30-90 secs.

All complaints have been registered using the GTAA complaints form.
Every complaint registered requested a telephone response. When there
are multiple complaints within a 2 hr. period, GTAA registers this as a single complaint with multiple sub-complaints.

The net effect of this is controlled statistical reporting, and does not show
a correct representation of actual neighbourhood impact.

This noise issue has been raised with various levels of government,
and is now actively under review by various ratepayer groups in
North Toronto.

Noise complaint – Lawrence Park

Subject: FW:
Date: Sat, 21 Nov 2009 01:03:18 +0000

Dear Sirs,
I would like to lodge a noise complaint regarding the flight path over my house that has been ongoing since at least this summer. There is a steady stream of planes that are flying directly over my house and there is little relief between the frequency, often not more that one minute. This is very prominent at night when I get home and it goes on until after midnight. These planes are extremely loud and I am not able to relax or get any sleep. I am not getting any relief. They then start again in the morning relentlessly bombarding me with loud thunderous noise.
I am a teacher and a mother and I haven’t been able to get any rest or sleep and the noise is accumulative, repeating every few minutes. This is a quiet residential area and there are  many young children and many of the neighbours are complaining. We thought this was only temporary.
If you could please help me I would be extremely grateful.

Yours sincerely,

Lawrence Park resident.
