montreal public health has been recommending for a decade that montreal establish a noise monitoring system, or noise observatory, he said. “if we compare it to air pollution, we have a very good air quality monitoring system. but there’s nothing comparable for noise.”
cities in europe are required by the european union to systematically monitor noise data and have noise action plans, kaiser said. in canada, “there’s no overarching noise control at the federal or provincial or municipal level. it’s still something we feel is a necessity in montreal.”
in the absence of a noise oversight body, it’s up to citizens to become “squeaky wheels” to get the volume turned down.
the courts became a front in the citizen war against airplane noise in quebec more than a decade ago.
and now in côte st-luc, citizens are taking steps to file a complaint with the canadian transportation agency about noise from canadian pacific railway’s st. luc yard.
“since november, the noise got tremendously bad,” said charles guérin, who has lived on merrimac rd., near an entrance to the rail yard, for seven years. he and his neighbours, who are used to a certain level of noise, are now being woken up by train idling and activity in the yard between 2:30 a.m. and 5:30 a.m., he said.
“we know when there are trains there. the whole house shakes.”
cp opened a new 118,000-square-foot multi-commodity transloading facility with 11 truck loading docks inside the yard in october.
residents find the complaint process long, however. the federal transportation agency, which is a quasi-judicial tribunal dealing with complaints about railway noise and vibration, won’t conduct an investigation or a hearing until the parties exhaust all steps for what it calls “collaborative complaint resolution.”
guérin said residents so far haven’t been able to talk directly with cp. the company communicated only with municipal officials in côte st-luc.
the official word from cp is that the company has not made changes to operations that would account for an increase in noise levels around the st. luc yard.
the number and length of trains that pass on cp’s network is “strictly a function of the amount of traffic that customers tender for movement, and therefore fluctuates with the economy,” stacy patenaude, cp’s manager for government affairs and communication, said in an email, adding that the st. luc yard must operate 24 hours a day. she said the company wouldn’t comment further when asked whether the new facility has increased activity in the yard.
the company’s promotional video for the new facility in the st. luc yard says it was intended to grow traffic.
as well, cp reported that it had broken multiple carload, revenue and tonnage records in its first quarter operating results for 2021.
therein lies the paradox of environmental noise: the more there is, the better it seems to be for the economy. and many will argue what’s good for business is good for society, even if some neighbourhoods must absorb the sounds of trucks rumbling across pavement, workers banging at construction sites, airplanes tearing through the sky and trains emitting a bone-rattling screech as they come to a halt.
but the flip side to that is the economic cost of noise pollution. and there is a cost, asserts the who and quebec public health.
in a 2015 report on environmental sound, quebec’s institut national de santé publique said a conservative estimate pegged the cost of noise pollution to the province at $680 million in 2013 alone. one well-documented economic consequence is lower property values on homes affected by transportation noise, it said. there’s also the financial cost tied to the negative health consequences of excess noise.
the city of montreal doesn’t have data on the number of people upset about transportation noise because it doesn’t track the type or location when it receives complaints, city spokesperson karla duval said in an email. in fact, the city’s website tells residents to contact adm or the railway companies about air or rail transport noise. mayor valérie plante’s office referred questions to the city’s communications office.
most people don’t know where to complain, or they’re too exasperated to wait on hold, said bill mavridis, an entrepreneur who created a mobile app in 2018 to make it easier to complain instantly about aircraft noise under trudeau airport flight paths.
when he moved to ahuntsic-cartierville borough in 2004, about 250 planes a day were flying overhead, he said. it soon became 600 a day.
mavridis said he created the aeroplainte app after adm reported receiving just 543 noise complaints in 2017. other major airports in canada were reporting thousands of noise complaints per year.
“i said there’s no way there’s no problem,” he said. “so i said how are we going to track data better? let’s give people a tool to file a complaint.”
in 2019, adm suddenly reported 48,273 complaints — two-thirds of them, it said, were transmitted through aeroplainte.
“they didn’t skyrocket,” mavridis said of the number. “they were finally representative.”
adm, which modernized its complaint management system in 2019, explained that its old system used to register multiple complaints from one person per day as one complaint.
even in the quiet of the pandemic, more people have downloaded his app, mavridis said. “i was surprised, but i figured it was because people were working from home.”
the argument of “why did you move next to the airport?” doesn’t hold, he added. the boroughs of rosemont—la petite-patrie and villeray—st-michel—parc-extension and the duvernay district of laval — all 10 to 15 kilometres from the airport — were among the top generators of complaints before the pandemic, mavridis said. none of adm’s seven fixed sound measuring stations are in ahuntsic, parc-extension or rosemont, even though they’re under flight paths, he noted. adm has one mobile station.
now, mavridis is building a citizen-based noise observatory with 40 airplane noise sensors, known as a noisys, from california tech company getnoisy. mavridis said he acquired a dozen of the noisys specifically for ahuntsic, with funding from the borough.
the airports contend they’re working on noise abatement.
“soundscape management is, and always has been, a priority for adm,” anne-sophie hamel, adm’s director of corporate affairs and media relations, said in an email. the airport authority “continues to put in sustained efforts to ensure a balance between air operations and cohabitation with the community.” in 2020, for example, adm held an online consultation on its updated soundscape management action plan.
even if the number of passengers was rising sharply before the pandemic, hamel said, the number of takeoffs and landings at trudeau airport remained relatively stable. planes are bigger and can carry more travellers, she said. as well, technological developments have led each new generation of aircraft to be less noisy than the previous one, hamel said.
st-hubert airport’s foyle said the airport has restricted times in the summer when its tenant flight schools can do “touch-and-gos” — touchdowns and immediate takeoffs, which generate a constant buzzing sound, she said. as well, tenants must install a muffler system on their fleets to cut noise, foyle said.
but mavridis said the noise problem starts at the federal level, where regulations are weak or non-existent.
for example, the federal government requires every airport to have a soundscape committee, with industry representatives, transport canada, elected officials and citizens. mavridis calls it “the lamest thing out there, but it meets the minimum requirements of the federal government.”
he also pointed out that a helicopter flying at 1,500 or 2,000 feet “is a very loud animal.”
but “there’s no law in canada that says you can’t make more than x level of noise over the city,” mavridis said.
under canadian aviation regulations, an airplane can fly no lower than 1,000 feet above the highest obstacle within a horizontal distance of 2,000 feet. a helicopter can fly no lower than 1,000 feet above the highest obstacle that’s 500 feet away. no regulation limits the number of aircraft on a route within a time period.
thierry dugrippe, general manager of collège air richelieu, a large flight school at st-hubert airport, says it would be nonsense to call the 10 daily sightseeing tours his company is flying over the island a nuisance for a city like montreal.
“it’s not 10 per hour,” he said. “we’re talking 10 by day.” it was three to five tours a day before the pandemic, he said. “yes, there’s an increase, but (not) a tidal wave.”
dugrippe recalled that complaints about airplane noise around st-hubert airport rose years ago even though the airport’s traffic had dropped since the 1980s. the population had aged and more people were staying at home, he said.
the pandemic is creating a similar effect, dugrippe said.
“what will happen is really simple,” he said. “when things return to normal with large planes, people will forget the small planes.”
they might not forget for long, however.
dugrippe said the industry anticipates a shortage of pilots in the next two years — so he’s expecting an “explosion” of registrations at flight schools.
st-hubert airport, meanwhile, has plans to develop commercial activity and attract low-cost and sun destination passenger flights from plattsburgh international airport’s market, foyle said.
and adm has plans, albeit on hold due to the pandemic, to build a new terminal to add capacity at trudeau airport.
back in westmount, mazza said he’s frustrated enough with the constant buzzing of flying lawn mowers that he’s considering moving away from montreal.
“i’m happy their business has doubled, but why make other people suffer?” he asked, referring to the helicopter company flying sightseers over the island.
“everybody should be happy and a winner. i don’t believe that one sector should be winning and because they’re winning, other people have to pay for it.”
nearly two-thirds of montrealers live in neighbourhoods where outdoor noise levels exceed world health organization guidelines and are loud enough to have long-term impacts on their health, says david kaiser, a physician responsible for environmental health for montreal public health.
“one of the concerning things about long-term exposure to noise is your body doesn’t get habituated,” kaiser said. “you can be in a noisy environment for 25 years, and your body doesn’t react less.”
montreal public health has been preoccupied by the health impact of environmental noise for 15 years, he said, adding that it was sparked by complaints about plane noise around trudeau airport.
according to the world health organization, environmental noise has negative effects on health, including annoyance, sleep disturbance and cardiovascular illnesses, notably hypertension, strokes and heart attacks. annoyance caused by environmental noise can lead to symptoms of anxiety and depression and reduce quality of life and well-being, it says.
sound levels, or intensities, are measured in decibels. experts use a-weighted decibels, or dbas, when describing sound level recommendations.
according to who guidelines, noise outside homes should not exceed an average of 55 dbas during the day, and 40 dbas at night. but given the difficulty of staying within the latter limit in an urban environment, the who recommends 55 dbas as the upper limit at night.
however, research by montreal public health, quebec’s institut national de santé publique and university researchers found that more than 60 per cent of the island’s population is exposed to higher than 55 dbas — even at night.
as well, one in five montreal adults reported sleep disturbances caused by environmental noise.
there’s a socioeconomic dimension to montreal’s outdoor noise problem, kaiser said: poorer neighbourhoods are more exposed to unhealthy levels of noise.
it’s “the same pattern we see for other environmental exposures,” he said. “that is, people in lower-income neighbourhoods are more exposed to noise, especially traffic noise. the most vulnerable are the most exposed.”
