Iroquois Falls' primary industry was a large mill producing newsprint and commercial printing papers.

The background of the town's name varies depending on the source, attributing it to invasions by the Iroquois on Huron or Ojibway villages.

Anson had been influenced by the garden city movement of urban planning, and was committed to building an elaborate town.

A Chicago architectural firm was hired to design the landscaping and houses, and work crews began clearing land in 1913.

A large church was built, the first English Catholic Parish in Northern Ontario, and today remains a historic landmark.

[citation needed] The paper mill created a dramatic change to the area, and people migrated to the community for work.

An area known first as "The Wye" (because the rail tracks split at this point) grew to the south, and was at first a ramshackle collection of cabins and shacks.

In contrast to Iroquois Falls, Ansonville had little town planning, and no water, sewer, or electrical service.

The paper mill, then called Abitibi-Price, merged with Stone-Consolidated, and then with Donohue Forest Products, and finally with Bowater to create Abitibi-Bowater.

[12] Resolute Forest Products announced the permanent closure of its mill in Iroquois Falls on 5 December 2014, eliminating 180 jobs.

"[4] In 2015, the Town of Iroquois Falls entered into an agreement with Resolute Forest Products, and Riverside Developments, regarding redeveloping the former mill site into a multi-use industrial facility, commercial-industrial park, or possibly a greenhouse complex.

'MusicMusicMusic' was an annual live event on the second weekend of August, and featured local musicians raising funds for community charities.
