The strange humming sound that has raised the ire of residents in the Windsor, Ont., area has made its way to the U.S. capital.
Windsor-West MP Brian Masse brought up the issue during a business trip in Washington, D.C., this week, where he met with Michigan Congressman John Dingell.
The noise, which sounds like an idling semi truck, started in February 2011.
Government officials and a consultant hired by the city of River Rouge, Mich., admitted late last year the rumbles and vibrations are an airborne sound wave originating from the vicinity of Zug Island, which is home to several industries on the U.S. side of the Detroit River.
Masse said government officials on both sides of the border agreed to exchange information about the low-frequency rumble, in the hopes of trying to "find a solution."
The New Democrat MP said he hopes Ottawa will get involved with diplomatic efforts to "get the wheels moving."
Although the hum is believed to be coming from Zug Island, the mayor of Red Rouge has said there's no money to investigate the matter further.
Windsor held a telephone town hall on the mysterious noise last week, which drew 23,000 area residents. One suggestion discussed at the meeting was to launch a class-action lawsuit against companies operating on the island.
Mass said last month he had written to Environment Minister Peter Kent, Canada's ambassador to the U.S. Gary Doer and the U.S. ambassador to Canada, David Jacobson, about the issue.
