Many human activities result in the creation of noise, which makes it a challenge to control in a dense and growing city like Toronto. Common source of noise include transportation (aircraft, road vehicles and, rail cars), construction and landscaping equipment, household appliances, power tools and sound systems.

Exposure to high levels of sound can result in adverse effects to humans, including:

  • Hearing problems.
  • Heart disease
  • Memory and mental function problems
  • Sleep disturbance
  • Annoyance/stress

Toronto Public Health addresses concerns due to noise by reviewing proposals and providing advice on major initiatives.
