Shannon is situated approximately 15 miles north, twenty minutes by car, of Quebec City, along the banks of the Jacques-Cartier River.
The first inhabitants that settled here were of Irish descent who came here in the pre-famine era, seeking a better life. These people became farmers and lumbermen, driving logs along the Jacques-Cartier River. Till now, many inhabitants have Irish roots, and Shannon is one of the strongest Irish communities in Quebec.
The municipality of Shannon was created in 1846, when citizens of the community decided to leave St. Catherine-de-Portneuf in protest against the municipal taxes. For a long time the exploitation of wood bound for the shipyards of Quebec was the most important activity here. The McCloskey Barn, built in the 19th century, stands as a historic reminder of the Irish pioneers who opened up this land. Shannon is located near Valcartier, an important Canadian military base.
Today hundreds of present and past citizens of Shannon are engaged in a class-action suit against the federal government. They allege that the chemical trichloroethylene - TCE seeped into the town's water supply.
TCE is a manufactured chemical mainly used as a solvent to remove grease from metal parts in the automotive and metals industries. Besides, it's used as an ingredient in adhesives, paint removers, typewriter correction fluids, spot removers, a chemical building block to make other chemicals, etc…
