Canadian town plagued by a mystery hum: MPs complain to Justin Trudeau about the 'Windsor Hum' - a strange vibrating sound that has lasted seven years

Canadian MPs have called on Justin Trudeau to do something about a mysterious vibrating noise heard across an Ontario city over the past seven years.

The 'Windsor Hum' - a bizarre, persistent rumbling sound like trucks idling - was first recorded in 2011 when residents complained of stress and difficulty sleeping.

Those who suffer the noise in and around the city of Windsor, just across the river from Detroit, have said that one of its worst aspects is its unpredictability.

The sound is so distressing that MPs have appealed to the government to intervene.
