The MacKenzie and Mann years continued and the community took on the characteristics of a booming town. It was gradually changing its form and style and even its name. At a mass meeting called by the first manager of the MacKenzie and Mann IR&C Company, J.L. Brass, it was decided that this bustling community should take on an identity of its own. Previously named Broad Cove Shean, Sithean, Broad Cove Coal Mines, Loch Leven, and Broad Cove Shore, J.L. Brass expressed the need that since most of the citizens were from Scotland they should adopt a Scottish name in honour of their homeland. Since many had emigrated from Inverness-shire the name chosen was Inverness, a name close to their hearts.

On April 6, 1904 the town was incorporated with a vote of 164-12 (Appendix F). The new town celebrated with parades, concerts, and much fanfare. The people took to the streets wearing their finest clothes and hopeful of a prosperous future. The Central Avenue Bandstand was the focal point for the many bands celebrating a new beginning. The town was proud, stable, and were administered by a competent and energetic Mayor and Council. These included: Mayor Dan R. MacLean (great-grandson of Roderick MacLean, one of the first settlers, 1811). Councillors James MacIsaac, Donald MacLeod, Hugh G. Cameron, John J. Rankin, John E. Beaton, and Archie J, MacIsaac, Clerk and Treasurer William D. Lawrence. Stipendiary Magistrate and Solicitor Frank MacEachern, Chief of Police A.D. Fraser.

The new town soon had a competent Fire Department, an impressive Federal Building constructed by the Dominion Government of Canada which served as a Post Office, Custom House, and Telegraph Office. It boasted six school buildings, two churches, multiple halls built by private organizations, elaborate commercial district, three hotels, many boarding houses and a Gentleman's Club. The three hotels were significant architectural structures and included the Inverness, Grand Central, and Imperial. The town was a vibrant place and open for business.
