Health risks from repetitive intrusive noise and fine particulate matter from low-altitude jet engine emissions, such as those that occur within the runway 24L/R approach path over Toronto, are of primary concern.
Noise deltas between ambient noise and over-flying jets cause sleep interruption and loss of focus in children at school.
– many shools are located under the Runway 24 flight path.
Quality of life and property enjoyment are also known impacts.
These are dramatic character alterations in neighbourhoods where residents want to escape city noise in their backyards.

Toronto commentary from Montreal excerpt (see link below)
Noise making Montrealers sick, study shows
Montreal levels are similar to those in other big cities, including Toronto.
“There’s a link between exposure to noise and our health,” said Richard Massé, director of the Montreal public health department. Pregnant women, seniors and people with chronic diseases are most susceptible.
Noise has three key adverse effects, Massé noted.
They are: annoyance (inability to concentrate, occasionally being awoken, difficulty carrying on conversations); sleep disturbance (frequent waking, which can affect health); and, most seriously, cardiovascular disease, especially high blood pressure, which increases as people are exposed to noise.
The department is monitoring noise at 200 locations across Montreal, and collecting data about the health of people who live nearby, Massé said.
The results, due later this year, are to be used by a committee the city of Montreal is creating. The noise-management committee is to include railways, Transport Quebec, Trudeau airport and the Port of Montreal.
Transport Quebec, which operates highways in Montreal, only looks into noise complaints when the noise level is 65 decibels or higher — 10 decibels more than the WHO guideline.
Asked about the Transport Quebec threshold, Massé would not comment directly but said 65 decibels“certainly has an impact on people who live nearby.
- If Montreal is taking action about this issue,what are the governments of Toronto and Ontario doing about this issue that is affecting the health of the residents of Toronto?
- What will these governments do to get the issue addressed by the Minister of Transport and the Ontario Health ministry?
Impacts to Children:
Cornell University – impact study on children: March 1998
Research indicates that fine particulate matter is of particular concern for children whose lungs are developing and have the potential for scarring from these fine particles. Properties of fine particulate matter have been documented as having a greater tendency to adhere to the lining of the lungs as this particulate matter is inhaled.
Studies have shown that emissions from aircraft can extend a significant distance (from a few kilometres to up to 15 kilometres) behind aircraft in the pattern. Busy downwind flight paths only add to this concentration and exposure.
